Thread: Lab 14

Here's what I need to do for Lab 14:

 
The StreetAddress class has this constructor:
 
StreetAddress( String street, String city,
               String state, String zip );
 
and the following methods:
 
void setStreet( String street ); and String getStreet();
 
void setCity( String city); and String getCity();
 
void setState( String state ); and String getState();
 
void setZIP( String zip ); and String getZIP();
 
String mailingLabel();.
 
The last of these returns the mailing address on two lines in the following form:
 
street
city, state zip
 
Use the following code segment to experiment with the behavior of this class — click the Run button and see what happens; change the code and click the Run button again to see the effect of your changes; repeat as often as you like.
 
 
 
Run
Write a definition for the StreetAddress class in the code area below.

Here is my code:

public class StreetAddress (String street, String city,String state,String zip) 
{
 
public void setStreetAddress(String Street, String City, String, State, String Zip){
    street = Street;
    city = City;
    state = State;
    zip = Zip;
} 
 
public String getStreet(){
    return street; 
}
 
public String getCity(){
    return city;
}
 
pubilc String getState(){
    return Zip;
}
}

Thx!

I'm actually making some progress. I'm glad its happening in such a short amount of time.

public class StreetAddress ()
    {
        public StreetAddress(){
 
        private String number;
        private String Street;
        private String city;
        private String zip;
 
        }
        public getStreet(){
            streetName = " ";
        }
        public getNumber(){
            StreetNumber = " ";
        }
        public getCity(){
            city = " ";
        }
        public String zip(){
            zip = " ";
        }
 
 
        public void AddressGetter(String YourStreetIs) {
            StreetNumber += YourStreetIs;
        }
 
        public void findAddress(double number){
            SteetNumber -= YourStreetIs;
        }
 
        public String returnStreet(){
            return street;   
        }
    }

How's that for a start? Haha, it's not a good start is it?

--- Update ---

Oh yeah, one more editation:

public class StreetAddress ()
    {
        public StreetAddress(){
 
        private String number;
        private String Street;
        private String city;
        private String zip;
 
        }
        public getStreet(){
            streetName = " ";
        }
        public getNumber(){
            StreetNumber = " ";
        }
        public getCity(){
            city = " ";
        }
        public String zip(){
            zip = " ";
        }
 
 
        public void AddressGetter(String YourStreetIs) {
            StreetNumber += YourStreetIs;
        }
 
        public void findAddress(double number){
            SteetNumber -= YourStreetIs;
        }
 
        public String returnStreet(){
            return street;   
        }
    }

I'll stop now, as I'm posting a little to much and it might get a little annoying. Sorry about that. Didn't mean to spam.

It's not annoying that you keep posting - that's what a forum is for. It is annoying or frustrating that we've told you repeatedly what getter/accessor and setter/mutator methods are, shown you examples, corrected your attempts, told you what's wrong and right with what you've done, and still you can't get it right. You are unable to grasp and apply the basic concept that getters/accessors return a value (hence the word "get") and setters/mutators set or change a value (hence the word "set"). In fact, as the code added to your last post shows, you can't even write a method that conforms to basic Java requirements. Why is that? You tell us what point there is to helping you when you don't apply what we tell you, and you continue to write nonsense like this (one example of several blatant syntax and concept errors in your code):

public getNumber(){
    StreetNumber = " ";
}

and then ask us what we think. What I wonder is why nothing we've told you over and over again has sunk in, and then I think that helping you is a complete waste of time. Show me I'm wrong.

I knew most of it was titled wrong, because I was sort of not focused on the titles. I actually tried to copy this guy's programming:

Accessors and mutators in Java - YouTube

I think that was a bad idea.

--- Update ---

Lol. like this?

public class StreetAddress
    {
        public StreetAddress(){
 
        private String number;
        private String Street;
        private String city;
        private String zip;
 
        }
        public String getStreet(){
            return Street;
        }
        public String getNumber(){
            return number;
        }
        public String GetCity(){
            return city;
        }
        public String GetZipCode(){
            return zip;
        } 
    }
 
Address firstAddress = new StreetAddress ("16", " 5th Street", " New York", " 89215");

I think everything there is a little better, except for the constructor.

I think I'm starting to get some of it.

--- Update ---

Wait, I edited an earlier post. I think I'll post it here:

   public String street;
 
    public String city;
 
    public String state;
 
    public String zip;
 
 
 
    public StreetAddress(){
 
        street = findStreet;
 
        city = findCity;
 
        state = findState;
 
        zip = findZip;
 
    }
 
 
 
   public int getStreet() {
 
      return street;
 
   }
 
   public void setStreet(int newStreet) {
 
      street = newStreet'
 
   }
 
 
 
   public int getcity() {
 
      return city;
 
   }
 
  public void setcity(int newCity) {
 
     city = newCity;
 
 
 
  }
 
 
 
   public int getState() {
 
      return state;
 
   }
 
  public void setState(int newState) {
 
     state = newState;
 
 
 
  }
 
 
 
  public int getZIP() {
 
      return zip;
 
   }
 
  public void setZip(int newZip) {
 
     zip = newZip;
 
 
 
  }
 
 
 
  }
 
 
 
}

--- Update ---

I'm just saving my code:

public class StreetAddress{
 
 
 
    public String street;
 
    public String city;
 
    public String state;
 
    public String zip;
 
 
 
    public StreetAddress(){
 
        street = findStreet;
 
        city = findCity;
 
        state = findState;
 
        zip = findZip;
 
    }
 
 
 
   public int getStreet() {
 
      return street;
 
   }
 
   public void setStreet(int newStreet) {
 
      street = newStreet;
 
   }
 
 
 
   public int getcity() {
 
      return city;
 
   }
 
  public void setcity(int newCity) {
 
     city = newCity;
 
 
 
  }
 
 
 
   public int getState() {
 
      return state;
 
   }
 
  public void setState(int newState) {
 
     state = newState;
 
 
 
  }
 
 
 
  public int getZIP() {
 
      return zip;
 
   }
 
  public void setZip(int newZip) {
 
     zip = newZip;
 
 
 
  }
 
 
 
}
 
  public String mailinglabel(){
 
      System.out.print(street);
 
      System.out.println(city + " " + zip);
 
  }
 
}

You've made no progress that I can see. What are findStreet, findCity, findState, and findZip? And how will this work:

public void setStreet(int newStreet) {
 
      street = newStreet;
 
   }

if 'street' is a String?

Example Construtor:

public class Name{
private String fName;
private String lname;
public Name(String fN, String lN)
{
fName = fN;
lName = lN;
}
}

}
}

I thought that you didn't declare fields variables in a constructor.

--- Update ---

@GregBrannon

I just sort of thought that a constructor looked like this per-say:

   public Bicycle(int startCadence, int startSpeed, int startGear) {
        gear = startGear;
        cadence = startCadence;
        speed = startSpeed;
    }

I couldn't see much difference between that, which I copied from a tutorial and what I did. I made the "find" variables as sort of like the "start" variables in the constructor in the tutorial I found. I'll give you a link so you can relate.

Classes (The Java™ Tutorials > Learning the Java Language > Classes and Objects)

That tutorial is where I got the idea from.

--- Update ---

Wait, is it because I didn't put parameter in mine like the tutorial did?

Why are you collecting programming 'ideas' from multiple sources? Some of those ideas may be good, others not so good, but you've demonstrated that you can't tell the difference or that you can't combine and apply the ideas, good or bad, into valid code. Stop jumping from video to tutorial to who-knows-what, collecting bits of code that you don't really understand and combining them without really thinking about or understanding the result. Fall back, regroup, and concentrate on one source, your textbook, if you have one, and any class notes you took or were given.

Your last post shows that you don't know what "declare a variable" means. Look that up. The constructor copied from the Oracle tutorials in post #12 and the one you posted in post #9 are clearly different, and my questions about post #9 addresses variable in the constructor that did not exist anywhere else in the class. That won't work.

You are nearly hopelessly confused and lost at this point, and if you don't find some way to ground yourself to truth and reality and start afresh from there, you won't survive this class.

I thought that declaring a variable essentially meant:

int five = 5;

It would store the number "5" in the data space, represented by 5, which is an integer. That's what my understanding is.

--- Update ---

Declaring the variable means assigning it the type "int."

As where is I declared it as "double" that would be a different declaration.

--- Update ---

Not the first part of being represented by "5."

So there are two parts to the first statement you posted, declaration and initialization. Take that thought and go back to your first statement in post #12, reread, rethink.

Okay, so how's this for a start:

 
public class StreetAddress{
 
 
 
   public String street;
 
   public String city;
 
   public String state;
 
   public String zip;
 
 
 
   public StreetAddress(String findStreet, String findCity,String findState,String findZIP){
 
       street = findStreet;
 
       city = findCity;
 
       state = findState;
 
       zip = findZIP;
 
   }
 
 
 
public String getStreet() {
 
   return street;
 
}
 
 
 
 
 
public String getcity() {
 
   return city;
 
}
 
 
 
 
 
public String getState(){
 
    return state; 
 
}
 
 
 
 
 
public String getZip() {
 
   return zip;
 
}
 
 
 
}
 
}

--- Update ---

I know that not everything is on there, but just to begin with. When the constructor and the getters get better, I'm going for the setters. I'm hoping that my constructors are getting just a tiny bit better because I'm going crazy doing this lol.

Well, you're way beyond the starting line - that's a good thing - and you're finally showing some progress. Except for inconsistent capitalization (not wrong, just annoying), random code indentation and spacing, and some odd or non-standard variable/method names, you've pretty much correctly written a class, its constructor with parameters, and getters/accessor methods.

Since you've been all over the map from where you started, you might want to look back at post #1 or review the assignment to make sure you're still on track.

Whatever conventions/standards you adopt for naming, capitalizing, code indenting, etc., be consistent. If you want to show your code to others, choose conventions and standards that are generally accepted by the community in which you show your work so they don't cringe at the mere sight of your code, but consistency is mostly for your own benefit. After you've written enough code and simply "know" what correct code looks like, even subtle inconsistencies will jump out at you as being suspect and potentially incorrect. Right now, most all of your code has those inconsistencies that indicate there might be problems, but it's getting better.

So now, hopefully I can get some setters working. Thanks.

Alright so, as always, my mutators don't work. Here's my code:

public class StreetAddress
 
{
 
 
 
    public String street;
 
    public String city;
 
    public String state;
 
    public String zip;
 
 
 
   public StreetAddress(String findStreet, String findCity,String findState,String findZIP){
 
 
 
    street = findStreet;
 
    city = findCity;
 
    state = findState;
 
    zip = findZIP;
 
   }
 
 
 
  public String getStreet() {
 
     return street;
 
  }
 
 
 
  public void makeStreet(String street){
 
      this.street = street;
 
  }
 
 
 
  public String getcity() {
 
     return city;
 
 
 
  }
 
 
 
  public void makeCity(String city){
 
      this.city = city;
 
  }
 
 
 
 
 
  public String getState(){
 
     return state;
 
  }
 
 
 
  public void makeState(String state){
 
      this.state = state;
 
  }
 
 
 
 
 
public String getZip() {
 
     return zip;
 
 
 
 
 
public void makeZip(String zip){
 
      this.zip = zip;
 
}
 
 
 
}
 
}
 
}

I want to emphasize anbin's point: a getter method to obtain the variable this' value is called getThis and a setter method to store a value in the variable 'this' is called setThis(). The naming is not debatable or a time to be original. There's a reason (probably several) for the naming convention. Conventions are conventions for a reason.
