Many Errors

**Woody619** · July 16th, 2010, 05:24 PM

I am doing a Parking Ticket Simulator for a Java class.

I am using NetBeans 6.8 and I keep getting error messages in my code. The two most prominent error messages are: '{' is expected and "non-static variable this cannot be referenced from a static context".

I have e-mailed my instructor, but I have not got any word back yet. If anyone could help me, it would be greatly appreciated.

Note: I did put "static" before class, but I have read from numerous sites that no output will be displayed.

Here is my code thus far, also if see any other errors or nuances that may pop up, please let me know.

Thank you for your help!

The warning and errors you receive should be pretty concise as to where the errors are occurring, so I suggest you read them carefully. Just by glancing at the code there are a couple obvious ones, for instance:

public static class ParkedCar(){
...
}

Is not a proper statement (hint: parenthesis).

**helloworld922** · July 16th, 2010, 05:47 PM

You can only use static with classes declared inside another class.

Also, when declaring classes, you don't put parenthesis after the class declaration

public class ParkedCar() // << wrong
{}
 
public class ParkedCar // << right
{}

Also, how do you you have your files organized? In Java, the name of the main "item" in that file (either a class, enum, or interface) must match the name of that file. Additionally, you can only have one top level item per java source file.

Look at the the error messages you are getting. Most of the time, they will provide great insite into what is wrong syntactically about the code (Java is much better at this than many languages).

Thank you guys for the help! I've redone my classes to where I am not receiving the '{' is expected error.

However, I am still receiving the static context message. I'm a beginner in Java and I am not quite sure what that message means.

I have looked online, but maybe I am over thinking the solution or I am blind to it.

**Woody619** · July 16th, 2010, 05:56 PM

PS- It seems I accidentally chopped off the top bit of my code. Maybe this can give you guys some more insight:

package parkingticketsimulator;
 
/**
 *
 * @author Wood Family
 */
public class Main {
 
    /**
     * @param args the command line arguments
     */
    public static void main(String[] args) {
        ParkedCar car = new ParkedCar("Ford", "1968", "Blue", "BR459", 125);
 
        ParkingMeter meter = new ParkingMeter(60);
 
        PoliceOfficer officer = new PoliceOfficer("John McClane", "8986");
 
        ParkingTicket ticket = officer.patrol(car, meter);
 
        if(ticket != null)
            System.out.println(ticket);
        else
            System.out.println("No Ticket is Needed!");
    }

Please surround your code with [highlight=Java]code goes here[/highlight]. It makes it much easier to read the code.

You are trying to statically access fields of an instance variable.

You need to have an instance before you can access those fields.

Here's an example of something similar to what you're doing, and a simple way to fix this problem. I'll let you fix your code accordingly.

public class MyClass
{
    public String name;
 
// wrong
    public String getNameAbbreviation()
    {
        // String is the class name, not the object we want to get the first character of
        return String.charAt(0);
    }
 
// right
    public string getName()
    {
        return name.charAt(0);
    }
}

Code tags in the future please.

Ok, wow, we have some issues here.

First of all, we need a main. So add something like this to your code (change the classname to whatever you want):

public class FileOpen
{
	public static void main(String args[])
	{
	}
...
}

The main will be what actually runs when the program is executed.

Now here is the code with some syntax issues fixed. I have commented out what is unnecessary and bolded what needed to be added:

public class FileOpen
{
	public static void main(String args[])
	{
	}
 
	public static class ParkedCar//()
	{
		private String make;
		private String model;
		private String color;
		private String license;
		private int minutesParked;
 
		public ParkedCar(String make, String model, String color, String license, int minutesParked) 
		{
			this.make = make;
			this.model = model;
			this.color = color;
			this.license = license;
			this.minutesParked = minutes;
		}
 
		public ParkedCar(FileOpen car2)
		{
			make = car2.make;
			model= car2.model;
			color = car2.color;
			license = car2.license;
			minutesParked = car2.minutesParked;
		}
 
		public String getColor() 
		{
			return color;
		}
 
		public void setColor(String color) 
		{
			this.color = color;
		}
 
		public String getLicense() 
		{
			return license;
		}
 
		public void setLicense(String license) 
		{
			this.license = license;
		}
 
		public String getMake() 
		{
			return make;
		}
 
		public void setMake(String make) 
		{
			this.make = make;
		}
 
		public int getMinutesParked() 
		{
			return minutesParked;
		}
 
		public void setMinutes(int minutesParked) 
		{
			this.minutesParked = minutesParked;
		}
 
		public String getModel() 
		{
			return model;
		}
 
		public void setModel(String model) 
		{
			this.model = model;
		}
 
		@Override
		public String toString()
		{
			String string = "Car Data: \n Make: " + make + "\n Model: " + model +
			"\n Color: " + color + "\n License Plate: " + license +
			"\n Minutes Parked: " + minutesParked;
			return string;
		}
	}
 
	public static class ParkingMeter//()
	{
		private int minutesPurchased;
 
		public ParkingMeter(int minutesPurchased) 
		{
			this.minutesPurchased = minutesPurchased;
		}
 
		public void setMinutesPurchased(int minutesPurchased)
		{
			minutesPurchased = minutesPurchased;
		}
 
		public int getMinutesPurchased()
		{
			return minutesPurchased;
		}
	}
 
	public static class ParkingTicket//()
	{
		private ParkedCar car;
		private PoliceOfficer officer;
		private double fine;
		private int minutes;
		double BASE_FINE = 25.0;
		double HOURLY_FINE = 10.0;
 
		public ParkingTicket(ParkedCar car, PoliceOfficer officer, double fine, int minutes) 
		{
			this.car = car;
			this.officer = officer;
			this.fine = fine;
			this.minutes = minutes;
		}
 
		public ParkingTicket(ParkingTicket ticket2)
		{
			car = ticket2.car;
			officer = ticket2.officer;
			fine = ticket2.fine;
			minutes = ticket2.minutes;
		}
 
		public void calculateFine()
		{
			if(ParkedCar.minutesParked - ParkingMeter.minutesPurchased <= 60)
				fine = BASE_FINE;
			else
				fine = BASE_FINE + (HOURLY_FINE * ((ParkedCar.minutesParked - ParkingMeter.minutesPurchased) / 60 ));
		}
 
		public double getBASE_FINE() 
		{
			return BASE_FINE;
		}
 
		public void setBASE_FINE(double BASE_FINE) 
		{
			this.BASE_FINE = BASE_FINE;
		}
 
		public double getHOURLY_FINE() 
		{
			return HOURLY_FINE;
		}
 
		public void setHOURLY_FINE(double HOURLY_FINE) 
		{
			this.HOURLY_FINE = HOURLY_FINE;
		}
 
		public ParkedCar getCar() 
		{
			return car;
		}
 
		public void setCar(ParkedCar car) 
		{
			this.car = car;
		}
 
		public double getFine() 
		{
			return fine;
		}
 
		public void setFine(double fine) 
		{
			this.fine = fine;
		}
 
		public int getMinutes() 
		{
			return minutes;
		}
 
		public void setMinutes(int minutes) 
		{
			this.minutes = minutes;
		}
 
		public PoliceOfficer getOfficer() 
		{
			return officer;
		}
 
		public void setOfficer(PoliceOfficer officer) 
		{
			this.officer = officer;
		}
 
	}
 
	public static class PoliceOfficer//()
	{
		private String name;
		private String badgeNumber;
 
		public PoliceOfficer(String name, String badgeNumber) 
		{
			this.name = name;
			this.badgeNumber = badgeNumber;
		}
 
		public PoliceOfficer(PoliceOfficer officer2)
		{
			name = officer2.name;
			badgeNumber = officer2.badgeNumber;
		}
 
		public void Patrol(ParkedCar car, ParkingMeter meter)
		{
			ParkingTicket();
		}
 
		@Override
		public String toString()
		{
			String string = "Officer Data: \n Name: " + name + "\n Badge Number: " + badgeNumber +
			"\n Minutes Illegally Parked: " + (ParkedCar.minutesParked - ParkingMeter.minutesPurchased) +
			"Fine: $" + ParkingTicket.fine;
			return string;
		} 
	[B]}[/B]
}

Now, we arent done, we still have some major structural issues. So, here we go:

1st issue. The variable minutes doesnt exist. I believe you attempted to send it minutesParked. Even so, this is an ill advised way of doing this.

public static class ParkedCar
{
	private String make;
	private String model;
	private String color;
	private String license;
	private int minutesParked;
 
	public ParkedCar(String make, String model, String color, String license, int minutesParked) 
	{
		this.make = make;
		this.model = model;
		this.color = color;
		this.license = license;
		[B]this.minutesParked = minutes;[/B]
	}
...
}

Here is what I would do:

public static class ParkedCar
{
	private String make;
	private String model;
	private String color;
	private String license;
	private int minutesParked;
 
	public ParkedCar(String make, String model, String color, String license, int [B]minutes[/B]) 
	{
		make = make;
		model = model;
		color = color;
		license = license;
		minutesParked = minutes;
	}
...
}

I can see what your trying to do, but it is unnecessary. By saying this.variable or object.variable it means you are trying to reference a variable, which you are, but you are referencing a variable that is part of your class, so you can just say variable1 = variable2 where variable1 is a class variable and variable2 is a constructor variable.

2nd issue. Non-static variables. The class that contains the calculateFine() method is static. Because of this, any variable you reference must also be static. But, the minutesParked and minutesPurchased methods have not been declared static.

public void calculateFine()
{
	if(ParkedCar.minutesParked - ParkingMeter.minutesPurchased <= 60)
		fine = BASE_FINE;
	else
		fine = BASE_FINE + (HOURLY_FINE * ((ParkedCar.minutesParked - ParkingMeter.minutesPurchased) / 60 ));
}

So, go to the ParkedCar and ParkingMeter classes and set these variables as static:

public static class ParkingMeter
{
	private [B]static [/B]int minutesPurchased;
...
}
 
public static class ParkedCar//()
{
	private String make;
	private String model;
	private String color;
	private String license;
	private [B]static [/B]int minutesParked;
...
}

You also have this issue later on with the variable fine:

public static class PoliceOfficer
{
...
	@Override
	public String toString()
	{
		String string = "Officer Data: \n Name: " + name + "\n Badge Number: " + badgeNumber +
		"\n Minutes Illegally Parked: " + (ParkedCar.minutesParked - ParkingMeter.minutesPurchased) +
		"Fine: $" + ParkingTicket.[B]fine[/B];
		return string;
	} 
}

So we need to set the fine variable as static:

public static class ParkingTicket
{
	private ParkedCar car;
	private PoliceOfficer officer;
	private [B]static [/B]double fine;
	private int minutes;
	double BASE_FINE = 25.0;
	double HOURLY_FINE = 10.0;
...
}

3rd issue. I'm not entirely sure what you are trying to do here, and neither is the complier:

public Patrol(ParkedCar car, ParkingMeter meter)
{
	ParkingTicket();
}

What this is saying is that you are creating the constructor for a Patrol object, which you havent made a class for. It is also saying that you are attempting to call a method "ParkingTicket()", which also doesnt exist in this class.
I think what you are trying to do is create a ParkingTicket object. Unfortunately, you dont have a constructor for ParkingTicket that has no constructors AND you have the declare the object as "new". I am also going to assume you want this to be a void method (doesnt return anything). So here is what that would look like:

public void Patrol(ParkedCar car, ParkingMeter meter)
{
	new ParkingTicket(car,this,0.0,0);
}

I would lastly advise removing all the unnecessary this.variable calls and setting method variables that are differently named than the class variables. This will prevent any mistaken mix-ups in variable changes.

Here is my suggested final code:

 
public class FileOpen
{
	public static void main(String args[])
	{
	}
 
	public static class ParkedCar
	{
		private String make;
		private String model;

A great thanks to everyone! Thank you for taking time out to help a n00b!

I apologize if I didn't seem to "get it", but I'm just a beginner and hoping to become proficient in this language, as well as many others.

I also want to add that I was using a UML and maybe I was not reading it properly, but under certain classes it said "setters and getters omitted".

I took that as being they omitted them from printing for the sake of brevity in the UML, so I was just hitting ALT + Insert to put in the setters and getters for each class that stated they were omitted.

Once again, thank you all so much for your help!

Sorry to bug you guys again. I need the patrol (ParkingTicket object) to return a value.

I have fixed everything else you all have helped me with and this seems to be the one loose string. Below is my main class and method and the ParkingTicket object that was created.

 
public class Main {
 
    /**
     * @param args the command line arguments
     */
    public static void main(String[] args) {
        ParkedCar car = new ParkedCar("Ford", "1968", "Blue", "BR459", 125);
 
        ParkingMeter meter = new ParkingMeter(60);
 
        PoliceOfficer officer = new PoliceOfficer("John McClane", "8986");
 
        ParkingTicket ticket = officer.patrol(car, meter);
 
        if(ticket != null)
            System.out.println(ticket);
        else
            System.out.println("No Ticket is Needed!");
    }

I feel I may be on the right track, but all I am doing is taking the calculateFine() method and applying to here as well.

For further guidance, this is what it states for the Police Officer class (which the ParkingTicket/patrol object is at)

Police Officer Class:This class should simulate a cop inspecting parked cars. The responsibilities of the class are as follows:

To know the cop's name and badge number.

To examine a ParkedCar object and a ParkingMeter object, and determine whether the parking time of the car has expired.

To issue a parking ticket -- generate a ParkingTicket object-- if the time of the car has expired.

 
private ParkingTicket patrol(ParkedCar carv, ParkingMeter meterv){
                    double ticket;
                    if(ParkedCar.minutesParked > ParkingMeter.minutesPurchased)
                        if(ParkedCar.minutesParked - ParkingMeter.minutesPurchased <= 60)
                            ticket = 25.0;
                        else
                            ticket = 25.0 + (10.0 * ((ParkedCar.minutesParked - ParkingMeter.minutesPurchased) / 60));
                        return ticket; ;
 
		}

Once again, thank you for all your help!

private ParkingTicket patrol(ParkedCar carv, ParkingMeter meterv)
{
                    double ticket;
                    if(ParkedCar.minutesParked > ParkingMeter.minutesPurchased)
                        if(ParkedCar.minutesParked - ParkingMeter.minutesPurchased <= 60)
                            ticket = 25.0;
                        else
                            ticket = 25.0 + (10.0 * ((ParkedCar.minutesParked - ParkingMeter.minutesPurchased) / 60));
                        return ticket; ;
}

Ok, well first off, you are wanting to return a ParkingTicket but you have declared ticket to be a double. So, in order to return a ParkingTicket, we have to make a ParkingTicket. Which means, we need a ParkedCar, a PoliceOfficer, a fine, and a minutes variable in order to create a ParkingTicket. Now, I would assume what the ticket variable in this code is supposed to be is the fine variable. And I would assume the minutes variable would be minutesParked - minutesPurchased ?

We also want to reference the variables of the objects we sent, not just the class variables. So, instead of ParkedCar.minutesParked, we want carv.minutesParked because that gets the minutesParked variable of our carv object.

If so, here is what you want:

private ParkingTicket patrol(ParkedCar carv, ParkingMeter meterv)
{
                    double ticket;
                    if(carv.minutesParked > meterv.minutesPurchased)
                    {
                        if(carv.minutesParked - meterv.minutesPurchased <= 60)
                            ticket = 25.0;
                        else
                            ticket = 25.0 + (10.0 * ((carv.minutesParked - meterv.minutesPurchased) / 60));
                     }
                     return new ParkingTicket(carv,meterv,ticket, minutesParked - minutesPurchased);
}

You may have the change that a bit if your calculations are wrong or if I'm incorrect with my assumptions.

Also, on a side note, when you have multiple if/else statements, it never hurts to include brackets. I'm not entirely sure, but I think the way you had it indicated the else being with the first if, where you actually wanted it with the second. By putting the brackets around your if/else statement, you are making sure that the intentions behind the if/else statements are not confused by the JVM.
