Thread: My fleet of squares doesnt work (simple high school work)

Hi guys I wasted my entire day today trying to figure out and I just can't. I lost all my hope.

Square:

package assignment1;
 
 
import java.awt.*;
 
public class Square  
{   
   private double x,y;      // Current position of the square.
 
   private Color color;     // The color of the square.
 
   private int side;   // The side of the square
 
   public Square() // constructor
   {
      x = 100;
      y = 100;
      side = 5;
	  color = Color.orange;
   }
 
 
   public void draw(Graphics g) 
   {
      // Draw the square in the graphics context g.  Note: The drawing color
      // in g is changed to the color of the square.
      g.setColor(color);
      g.fillRect( (int)(x), (int)(y), (int)(side), (int)(side) );
   }
 
   public void setSide(int r)
   {
       side = r;
   }
 
   public int getSide()
   {
       return side;
   }
 
   public int getX()
   {
        return (int) x;
   }
 
   public int getY()
   {
        return (int) y;
   }
 
   public void setX(int xIn)
   {
       x = xIn;
   }
 
   public void setY(int setY)
   {
       y = setY;
   }
}  // end class Square

This is the square class, it draws an orange square that moves around in the applet viewer, works fine and as it supposed to do.

Ship:

package assignment1;
 
import java.awt.*;
 
public class Ship
{
    private Square[] fleetMembers; // declare fleetMembers as an array of Square
    private int total = 5; // Max number of squares in fleet
    private double x,y; 
    Ship() // Constructor
    {
        x = 100;
        y = 100;
        fleetMembers = new Square[total]; // create an empty array with 5 "locations"
        for (int i = 0; i < total; i++) // loop: carry on whilst i is less than 5, add 1 each cycle
        {
            fleetMembers[i] = new Square();  // create a Square object for location [i] in the array
            fleetMembers[i].setX (i * 10); // multiply i by 10, and pass this to the setX method
            fleetMembers[i].setY (i * 10); // multiply i by 10, and pass this to the setY method
        }
    }
 
    public void draw(Graphics g)
    {
        for (int i = 0; i < total; i++) // loop: carry on whilst i is less than 5, add 1 each cycle
        {
            fleetMembers[i].draw(g);    // ask fleetMember[i] to draw itself
        }
    }
 
    public void goSouth(int howFar)
    {
        for (int i = 0; i < total; i++) // loop: carry on whilst i is less than 5, add 1 each cycle
        {
            // ask fleetMember[i] for its current Y position
            // then add howFar (howFar to go south) to it
            // then pass this to the setY method 
            fleetMembers[i].setY (fleetMembers[i].getY() + howFar); 
        }
    }    
 
   public int getX()
   {
        return (int) x;
   }
 
   public int getY()
   {
        return (int) y;
   }
 
   public void setX(int xIn)
   {
       x = xIn;
   }
 
   public void setY(int setY)
   {
       y = setY;
   }
 
 
}

This is my ship class, it is basically a set of 5 squares that move around together, works fine as well.

The problem begins here:

package assignment1;
 
import java.awt.*;
 
public class FleetOfShips
{
    private Ship[] fleetMembers; // declare fleetMembers as an array of Ship
    private int total = 5; // Max number of Ships in fleet
    private double x,y; 
    FleetOfShips() // Constructor
    {
        x = 100;
        y = 100;
        fleetMembers = new Ship[total]; // create an empty array with 5 "locations"
        for (int i = 0; i < total; i++) // loop: carry on whilst i is less than 5, add 1 each cycle
        {
            fleetMembers[i] = new Ship();  // create a Ship object for location [i] in the array
            fleetMembers[i].setX (i * 50); // multiply i by 10, and pass this to the setX method
        }
    }
 
    public void draw(Graphics g)
    {
        for (int i = 0; i < total; i++) // loop: carry on whilst i is less than 5, add 1 each cycle
        {
            fleetMembers[i].draw(g);    // ask fleetMember[i] to draw itself
        }
    }
 
    public void goSouth(int howFar)
    {
        for (int i = 0; i < total; i++) // loop: carry on whilst i is less than 5, add 1 each cycle
        {
            // ask fleetMember[i] for its current Y position
            // then add howFar (howFar to go south) to it
            // then pass this to the setY method 
            fleetMembers[i].setY (fleetMembers[i].getY() + howFar); 
        }
    }    
 
   public int getX()
   {
        return (int) x;
   }
 
   public int getY()
   {
        return (int) y;
   }
 
   public void setX(int xIn)
   {
       x = xIn;
   }
 
   public void setY(int setY)
   {
       y = setY;
   }
 
 
}

This is my FleetOfShips code. It is supposed to be a set of ships moving around together, but for unknown to me reasons it doesn't work. It does compile without any problems but when I run the applet it doesn't do anything.

Guys please help me, the deadline is for tomorrow and I spent last 7 hours trying to figure this out. I lost all my hope.

It shows just a single fleet of the squares (5 squares) in a shape defined in the "Ship" class and it doesn't move when I click it.

I got UML as an example of how to do it that I can paste here but it doesn't really help me. :/

Sorry man I am really new to java, we started it recently in school and I am not the best at it. Sorry for all the problems.

I decided to start over because my previous project was a massive mess, but it displays an error:

http://puu.sh/73C9h.png

this is the actual code for Square and Ship classes:

package assignment1;
 
import java.awt.*;
 
public class Square  
{   
   private double x,y;    
 
   private Color color;    
 
   private int side;
 
   public Square()
   {
      x = 100;
      y = 100;
      side = 5;
	  color = Color.orange;
   }
 
 
   public void draw(Graphics g) 
   {
      g.setColor(color);
      g.fillRect( (int)(x), (int)(y), (int)(2*side), (int)(2*side) );
   }
 
   public void setSide(int s)
   {
       side = s;
   }
 
   public int getSide()
   {
       return side;
   }
 
   public int getX()
   {
        return (int) x;
   }
 
   public int getY()
   {
        return (int) y;
   }
 
   public void setX(int xIn)
   {
       x = xIn;
   }
 
   public void setY(int setY)
   {
       y = setY;
   }
}

package assignment1;
 
 
public class Ship extends Square  
{   
 
   public Ship()
   {
      Square();
   }
 
   public void draw() 
   {
      int side = SuperClass.getSide();
      int x = SuperClass.getX();
      int y = SuperClass.getY();
 
 
      g.setColor(color);
      g.fillRect( (int)(x), (int)(y), (int)(2*side), (int)(2*side) );
 
      g.setColor(color);
      g.fillRect( (int)(x), (int)(y - side), (int)(2*side), (int)(2*side) );
 
      g.setColor(color);
      g.fillRect( (int)(x - side), (int)(y - side), (int)(2*side), (int)(2*side) );
 
      g.setColor(color);
      g.fillRect( (int)(x + side), (int)(y - side), (int)(2*side), (int)(2*side) );
 
      g.setColor(color);
      g.fillRect( (int)(x), (int)(y - (2*side)), (int)(2*side), (int)(2*side) );
   }
 
}

Basically I need to have a square class that draws a square in the applet, then a ship class that draws 5 squares in a cross shape.

I really appreciate your help

Thanks man, I managed to make it work, i wouldn't be able to do it without your help. Really, thanks <3
