    Cool accessor and modifier method exercise; exercise 100

    Non-editable code:

     
    public class APPoint 
      { 
        private double myX; 
        private double myY; 
     
        public APPoint( double x, double y ) 
        { 
          myX = x; 
          myY = y; 
        } 
     
        public void move( double x, double y ) 
        { 
          myX += x; 
          myY += y; 
        } 
     
        public double getX()  
        { 
          return myX; 
        } 
     
        public void setX( double x ) 
        { 
          myX = x; 
        } 
     
        public double getY() 
        { 
          return myY; 
        }

    Here's my code:

     
    public double setY(){
        return myY = y;   
    }

    Here is the continuing, non editable code:

      } 
     
      public static void main( String[] args ) 
      { 
        APPoint a = new APPoint( 15.0, 4.0 ); 
        APPoint b = new APPoint( -4.0, 8.2 ); 
     
        a.setX( 0.0 ); 
        b.setY( a.getY() ); 
     
        System.out.println( "a is (" + a.getX() + "," + a.getY() + ")" ); 
        System.out.println( "b is (" + b.getX() + "," + b.getY() + ")" ); 
      }

    I'm looking up tutorials on how to do this stuff myself, but I'm just asking in case I happen to stumble upon something that might work. I'm just looking for suggestions on tutorials, articles, etc that may help. I'm not looking for specific help yet. I mean, since I want to try to figure this stuff out on my own but I thought that getting suggestions from a forum might help. I'm using youtube and google already. Lol.

    How's this different from your other thread?

    It's a different part of the code to complete. Maybe I should look at my old thread. Thanks, haha. I didn't notice that.

    --- Update ---

    made it work:

    public double setY(double y){
        myY = y;
        return y;
    }

    Why return the value of the arg passed in the method call?
    settor methods don't normally return a value.
    If you don't understand my answer, don't ignore it, ask a question.

    Alright. Good point. It still worked though. Your saying part of that was unneeded? Ok. It gave me an error because it wouldn't return any value. It said "no return type." That's all. It wouldn't work until I returned y. Does that mean something's still wrong?

    Settors are not intended to return a value. They are normally defined to return void.
