Header information of any image file

Question

but i dont want to use the AWT package of java

Answer 1

I don't know any other way. I used the following -
public void paint(Graphics g){
     Toolkit kit = Toolkit.getDefaultToolkit();
     Image imageA = kit.getImage("c:\\\\javaproj\\javalab\\image.gif");
     g.drawImage(imageA, 555, 5, 50, 50, this);
