A simple applet with a simple line

You see a simple line in between a rectangle from 200X200 pixels.

This line is drawn in the absolute way. The code is

public class Voorbeeld2 extends java.applet.Applet

{   double a = 1.5,b = 200.0,y3;
    int t,tmax=250,yi=150,youd;

public void init() 
      {    
	 y3 = -a*t+b;
	 youd = (int) y3;
      }
	
public void paint(Graphics g)
	{	
	init();
	for ( t=0; t < 300 ; t = t+1)
		{
		 y3 = - a * t + b;
		 yi = (int) y3; 
		 g.drawLine(t, youd, t+1, yi);
		 youd = yi;
		}
	}
}
