Stuck and need help please

Question

I am a student and I am stuck. I need to draw 100 random lines using the method drawLine. I do not know how to incorporate the random number . I know how to draw a set number of lines (such as 7)...Below is the code I have so far.
import java.awt.*;
import javax.swing.*;
public class RandomLines extends JFrame {
//     constructor sets window's title bar string and dimensions
     public RandomLines()
          super("Random Line ScreenSaver");
          setSize( 475, 430 );
          setVisible( true );
//      display lines
public void paint (Graphics g)
     super.paint(g);     //call superclass's paint method
     int xValues[] = { 70, 90, 100, 80, 70, 65, 60 };
     int yValues[] = { 100, 100, 110, 110, 130, 110, 90};
     g.drawPolyline(xValues, yValues, 7);
//execute application
public static void main ( String args [])
     RandomLines application = new RandomLines();
     application.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
}

Here's enough to get you unstuck.import java.util.Random;
Random rand = new Random();
xValues[i] = rand.nextInt(width);
