25. DDA LINE ALGORITHM

Code:

import java.io.*;

import java.awt.*;

import java.applet.*;

import java.util.*;

public class DDA extends Applet

{

public void paint(Graphics g)

{

double dx,dy,steps,x,y,k;

double xc,yc;

double x1=200,y1=500,x2=600,y2=200;

dx=x2-x1;

dy=y2-y1;

if(Math.abs(dx)>Math.abs(dy))

steps=Math.abs(dx);

else

steps=Math.abs(dy);

xc=(dx/steps);

yc=(dy/steps);

x=x1;

y=y1;

g.fillOval(200,500,5,5);

for(k=1;k<=steps;k++)

{

x=x+xc;

y=y+yc;

g.fillOval((int)x,(int)y,5,5);

}

}

}
