How can paintcomponent be called by us

[creativehacker]

I wrote a program where I should draw some stuff whenever a key is pressed.
The drawing is done whenever the key is pressed but can be seen only when i resize the window..

public void keyPressed(KeyEvent e)  {
Graphics2D g2 = image.createGraphics();
if(e.getKeyCode()==37) 
	{
	System.out.println("left is pressed");
	key=LEFT;
sp.SnakeMove(key);
	}
if(e.getKeyCode()==38) 
	{
	System.out.println("up is pressed");
key=UP;
sp.SnakeMove(key);
	}

if(e.getKeyCode()==39)
	System.out.println("right is pressed");

if(e.getKeyCode()==40)
	System.out.println("down is pressed");

}
});

.........
.......
public void SnakeMove(int key)
	{
	//revalidate();
	//repaint();
	int x1,y1;
	System.out.println("key=="+key);
	String str;
	 Graphics2D g2 = image.createGraphics();

switch(key){

case LEFT:
	str="--";
            g2.drawString(str, 40, 150);
			g2.drawRect(10,10,100,100);
			System.out.println("String drawn");
			revalidate();
			break;

case UP:
	str="|";
        g2.drawString(str, 45, 150);
	System.out.println("String drawn");
	revalidate();
			break;
			
}//end if switch
repaint();
	}//end of snakeMove function

You need to call repaint().
