Hi All,
I am a new beginner in Java who gave myself an exercise which briefly
requires that I produce an applet which generates positive integers
(1,2,3,..) and displays each one, together with a suitable message, i.e.
"The number is : 2", at two-second intervals. Can anyone point out why my
program below doesn't produce the expected results when run please ?
/*an applet which generates positive integers (1,2,3...)and displays each
one, together
with a suitable message, at two-second intervals*/
import java.awt.*;
import java.awt.Font;
import java.awt.Color;
import java.awt.Graphics;
public class Integers extends java.applet.Applet
{
Font f = new Font ("Courier",Font.BOLD,24);
int num, value; // declare variables
public void init()
{
Font f = new Font("Courier",Font.BOLD,24);
}
public void run()
{
while (true)
{
for (num = 1; num >= 1; num = num++)
{
value = num;
repaint();
try {Thread.sleep(1000);}
catch (InterruptedException e){}
}
}
}
public void update(Graphics g)
{
paint(g);
}
public void paint (Graphics g)
{
g.setFont (f);
g.setColor(Color.red);
g.drawString("The number is : " + value, 10, 20);
}
}
Thanks
