Printing arrays

**polop050505** · April 25th, 2013, 08:55 PM

I'm trying to print an array of objects.
Also numOfVehicles seems to be incrementing because when I initialize it to anything above 8, it prints the number plus 8. If numOfVehicles is not initialized of initialized to something less than 9, it gives an ArrayIndexOutOfBoundsException.
When I'm able to print with out a run-time error, the array just prints null. How do I print the entire array?
I also have a toString method in the Vehicle class. I have a FleetApp class as well.
Here's whats in the input files.

How is the code executed for testing? I don't see a main() method

**polop050505** · April 26th, 2013, 12:13 PM

Sorry, I forgot to post that.

public class FleetApp
{
	public static void main(String[] args)
	{
		Fleet flt = new Fleet();
		File input1 = new File("CarFleet.txt");
		File input2 = new File("SUVFleet.txt");
		flt.read(input1, input2);
	}
}

**Norm** · April 26th, 2013, 12:26 PM

Also the code is missing the import statements and class definitions needed to compile the code.

Also copy the full contents of the console window from when the code is executed and paste it here.

**polop050505** · April 26th, 2013, 12:46 PM

import java.io.File;
 
public class FleetApp
{
	public static void main(String[] args)
	{
		Fleet flt = new Fleet();
		File input1 = new File("CarFleet.txt");
		File input2 = new File("SUVFleet.txt");
		flt.read(input1, input2);
	}
}

When numOfVehicles is initialized to 0.

Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException: 0
at Fleet.read(Fleet.java:80)
at FleetApp.main(FleetApp.java:32)

When numOfVehicles is initialized to 10.

null
18

--- Update ---

I also have the import statements in the Vehicle class.

**Norm** · April 26th, 2013, 12:54 PM

Still need the Vehicle class to compile and test.
What are the contents of each of the files the program reads?

The Scanner class needs an import.

Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException: 0
at Fleet.read(Fleet.java:80)

The error happened at line 80 in the Fleet class, but the Fleet class is less than 80 lines long????

**polop050505** · April 26th, 2013, 01:34 PM

ok, here's all 3 updated classes. I have the contents of the files in my original post.
The error in the fleet class is System.out.println(vhcl[i]);
(I know the comments are off, I haven't worked on them yet)

What are the contents of each of the files the program reads?

			System.out.println(vhcl[i]);
			System.out.println(numOfVehicles);

What do you expect to be printed by these two statements?
What is the variable: numOfVehicles supposed to contain?
If you initialize it to 10, then it's value will reflect that starting value.

**polop050505** · April 26th, 2013, 02:41 PM

I expect it to print out exactly the way it come in. So like this:

numOfVehicles is the number of vehicles that I read from the 2 files, or the number of objects in the array. So it should be 8 after it reads the files.
I realize that initializing numOfVehicles to ten means that is the starting value, I'm just confused on how if I initialize it to 0, it will increment, but I still get the java.lang.ArrayIndexOutOfBoundsException: 0 error.

--- Update ---

Actually, shouldn't it be using the toString method from the Vehicle class?

**Norm** · April 26th, 2013, 02:58 PM

			System.out.println(vhcl[i]);    //????? What is in this slot in the array?
			System.out.println(numOfVehicles);

What do you expect to be printed by these two statements?
What is the variable: numOfVehicles supposed to contain?
If you initialize it to 10, then it's value will reflect that starting value.

numOfVehicles is the number of vehicles that I read from the 2 files, or the number of objects in the array. So it should be 8 after it reads the files.

It does not start at 0:

private int numOfVehicles = 10;

If you define the array to be much larger that all the number of objects that are put into it, there won't be an ArrayIndexOutOfBoundsException. Say 300 or 1000.
Use the numOfVehicles to count the number of objects that have been put into the array and later to control all array references that search through the array.

**polop050505** · April 26th, 2013, 03:20 PM

System.out.println(vhcl[i]);

Honestly, I don't really know what it in that slot in the array, I think the last index the scanner reads. I realize now that I am trying to use the toString method in the Vehicle class to print the contents of the array, and I'm not sure how to do it.

private int numOfVehicles = 10;

Ok, say I initialize numOfVehicles to 0. Why is there an error if I am incrementing numOfVehicles after it reads one in? Shouldn't that set the array to hold 8 objects?

**Norm** · April 26th, 2013, 03:28 PM

Post the new version of the code. It should define a large enough array and use the numOfVehicles variable to count the Vehicles as they are added.

how to do it.

For testing use an index of 0 to show the first object in the array:

System.out.println(vhcl[0]);

**polop050505** · April 26th, 2013, 03:59 PM

Do you mean just to initialize it to ten or something like that? Because then numOfVehicles will print as 18 when it should be 8.

Why is it not printing with the assigned values from the files it reads?

**Norm** · April 26th, 2013, 04:15 PM

Do you mean just to initialize it to ten or something like that?

No. Initialize numOfVehicles to 0
Define the Vehicle array with enough slots to hold the most possible data: 300 or 1000. This is a problem with arrays that will go away when you learn to use ArrayLists

VIN: null
Make: null
Model: null
Year: 0 Value: 0.0 Miles Driven: 0.0 Last Oil Change: 0.0 Type:

Look at the Vehicle class to see why the class variables do not get assigned values.

**polop050505** · April 26th, 2013, 04:42 PM

I defined the array to hold 100 in the constructor in the Fleet class. Is that right? It works correctly.
I the Vehicle class I set the parameters equal to the variables and that worked also.

Here's what it prints:

VIN: 1256BB03457
Make: Hyundai
Model: Santa Fe
Year: 2011 Value: 18556.0 Miles Driven: 31195.0 Last Oil Change: 27301.0 Type: c
8

One last question. Do I have to do this:

System.out.println(vhcl[0]);
System.out.println(vhcl[1]);
System.out.println(vhcl[2]);
System.out.println(vhcl[3]);
System.out.println(vhcl[4]);
System.out.println(vhcl[5]);
System.out.println(vhcl[6]);
System.out.println(vhcl[7]);

to print every object?

Look at all those statements that have an index goes from 0 to 7. That looks like the code should use a for loop and have the code use the loop's variable as an index into the array. The loop should use the value of the numOfVehicles variable to know when to stop looping.

I did that and it works.
Thank you very much, you were very helpful.
