Random Line Colors? noob needs helppppp :(((

Question

How do you make a program with random line colors heres my program:
import java.awt.*;
import java.applet.*;
import java.util.*;
import java.util.Random;
public class Lab6 extends Applet
     public void paint(Graphics g)      
          g.drawLine(0,300,800,300);
          g.drawLine(400,0,400,600);
          Random rand = new Random(12345);
          for(int x=0;x<=100;x=x+1)
          g.drawLine(rand.nextInt(400),rand.nextInt(300),rand.nextInt(400),rand.nextInt(300));
rand.setSeed(12345);
          for(int x=0;x<=100;x=x+1)
          g.drawLine((rand.nextInt(400) + 400),rand.nextInt(300),(rand.nextInt(400) + 400),rand.nextInt(300));
i need to make random line colors for the second loop and i dont get how. i can only set the lines for the second loop to one color. please help! i'm a real noob. =(

Answer 1

This gets the color with a hex integer. You can use
new Color(seed.nextInt(256), ...
import java.applet.*;
import java.awt.*;
import java.awt.event.*;
import java.util.Random;
public class Lab6 extends Applet
    Random rand = new Random(12345);
    Random seed = new Random();
    public void paint(Graphics g)
        super.paint(g);
        g.drawLine(0,300,800,300);
        g.drawLine(400,0,400,600);
        for(int x=0;x<=100;x=x+1)
            g.drawLine(rand.nextInt(400),rand.nextInt(300),
                       rand.nextInt(400),rand.nextInt(300));
        rand.setSeed(12345);
        for(int x=0;x<=100;x=x+1)
            g.setColor(getColor());
            g.drawLine((rand.nextInt(400) + 400),rand.nextInt(300),
                       (rand.nextInt(400) + 400),rand.nextInt(300));
    private Color getColor()
        return new Color(seed.nextInt(0xffffff));
    static WindowListener closer = new WindowAdapter()
        public void windowClosing(WindowEvent e)
            System.exit(0);
    public static void main(String[] args)
        Applet applet = new Lab6();
        Frame f = new Frame();
        f.addWindowListener(closer);
        f.add(applet);
        f.setSize(800,600);
        f.setLocation(50,50);
        applet.init();
        f.setVisible(true);
}
