My first attempt at a basic java applet failed. i can't figure out why the rectangle is not moving
public class Basics extends Applet{
int x = 0;
int y = 0;
public void init(){
setSize(500,500);
}
public void start(){
Thread a = new Thread();
a.start();
}
public void run(){
while(true){
x = 100;
y = 100;
repaint();
try{
Thread.sleep(18);
}
catch(InterruptedException e){}
}
public void paint(Graphics g){
g.setColor(Color.red);
g.fillRect(this.x,this.y,25,25);
}
}
Do not increment x and y and then redraw so the square can move

You have to increment your x and y values, now you only assign values to it. Change it like this:
public void run(){
while(true){
x += 100;
y += 100;
repaint();
try{
Thread.sleep(18);
}
catch(InterruptedException e){}
}

In your startup method, you don't increment X and Y, you set them.
Try to do
x += 100; y += 100;
I would use lower values, but I start at 1.
