Using candidates as objects

[jhamill]

Hey so for my lab we were given this code and told to fix it so that each candidate's information is printed on the appropriately colored background. The voting space for sarah is supposed to be on a green background, and the voting space for joe is supposed to be on a red back ground. My new code which DOES NOT WORK is listed after the old, given code that we start with.

}

ALSO this is the candidate class that these applets are referencing

import java.awt.Color;
import java.awt.Graphics;


public class Candidate {
	private Color color;
    protected String name;
    protected int votes;
    private int x, y, width, height;
    public Candidate(Color c, String name, int x, int y, int width, int height) {
            votes = 0;
            this.name = name;
            color = c;
            this.x = x;
            this.y = y;
            this.width = width;
            this.height = height;
    }
	public void paint(Graphics g) {
		// TODO Auto-generated method stub
	}
	public void registerVote() {
		// TODO Auto-generated method stub
		
	}
}

Can you be more specific about your problem.
If all your paint() methods are drawing on the same Graphics context, you need to pass each of them the bounds of the box that they can draw in.
Your Candidate's paint method needs code to fill in the color and draw the name.
