x=0;
if(x>= 1180)
x=1180;
if(y <= 20)
y = 20;
if(y >= 780)
y = 780;


}
public void setXDirection(int xdir){
xDirection = xdir;

}

public void setYDirection(int ydir){
yDirection = ydir;
}

public class AL extends KeyAdapter{
public void keyPressed(KeyEvent e){
int Keycode = e.getKeyCode();
if(Keycode == e.VK_UP){
setYDirection(-1);

}
if(Keycode == e.VK_LEFT){
setXDirection(-1);

}
if(Keycode == e.VK_DOWN){
setYDirection(+1);

}

}

public void paintCopmponent(Graphics g){

g.fillRect(ob.x, ob.y, ob.width, ob.height);


g.setColor(Color.blue);
//draw player 1

g.fillRect(x, y,p1.width, p1.height);


if(p1.intersects(ob)){

}
//Collision












//paint it all
repaint();

Please Edit your post and wrap your code with[code=java]<YOUR CODE HERE>[/code] to get highlighting.

When you change the x and y values of the thing that is moving, you could test the new values to see if they will cause a collision.
