needs help making battleship in java

[aznkid1221]

I have to make a battleship in java for school, i got some of the codes tats already came with the project. Can someone tell me what other classes i need, and what methods i need to write in them?

import javax.swing.*;
import java.awt.*;
import java.awt.event.*;

public class BattleScreen extends JFrame {

private BattlePanel bp;

public BattleScreen(){
super("Battle On");
bp = new BattlePanel(10);
getContentPane().add(bp);
setSize(800,400);
setDefaultCloseOperation(EXIT_ON_CLOSE);
}





public static void main(String [] args){
new BattleScreen().show();
}

}

public class Coor {

int x,y;

public Coor(int x, int y){
this.x = x;
this.y = y;

}

public int x(){
return x;
}

public int y(){
return y;
}

public boolean equals(Object o){
if (o instanceof Coor){
return x == ((Coor)o).x && y == ((Coor)o).y;
}

return false;
}

public String toString(){
return x+" , "+y;
}
}

Didn't that sound strange as you were typing it?

[Fubarable]

If you ask for our suggestions without first trying to do it yourself, you'll be cheating yourself out of a valuabe experience. Why not give it a go first, and then if your ideas don't work out come on back and we can look at your code. Much luck.

i have tried, made 4 prototypes, 2 of which i use those codes above and trying to fill in the missing ones, and another 2 i tried making a new battleship project from beginning

[aznkid1221]

this is what i have so far

 public class BattleScreen {
	public static void main(String [] args){
	int[][]myfield = new int [10][10];
	int[][]compfield = new int [10][10];
	int[][]pos = new int [10][10];
	Board board = new Board(myfield);
	Board comboard = new Board(compfield);
	int hit =0;
	int comphit=0;
	
	Ship boat = new Ship(2,"Boat");
	boat.placeShip(myfield);
	boat.placeShip(compfield);
	
	Ship cruise = new Ship(3,"Cruise");
	cruise.placeShip(myfield);
	cruise.placeShip(compfield);
	
	Ship sub = new Ship(4,"SubMarine");
	sub.placeShip(myfield);
	sub.placeShip(compfield);
	
	Ship battle = new Ship(5,"BattleShip");
	battle.placeShip(myfield);
	battle.placeShip(compfield);
	
	Ship air = new Ship(6,"AirCraftCarrier");
	air.placeShip(myfield);
	air.placeShip(compfield);
	
	while (hit <20 && comphit<20){
	board.displayField(myfield);
	comboard.displayField(compfield);
	run.attack(pos,compfield);
	run.attack(pos,myfield);
	}

I have no idea what to do next

Does it compile? Does it run correctly? If not what's the problem and where are you stuck with coming up with a solution?

[aznkid1221]

when i try to run it, nothing happens.
