在paint（）中仅运行一次方法（Java）

Question

Im trying to run a method only once when I call it in the paint () method, but when I call it normally it just runs over and over. Example:

private void someMethod ()
{
 System.out.println ("Success");
}
@Override
public void paintComponent (Graphics g)
{
 someMethod ();
 repaint ();
}

This will output "Success" forever, I only can output it once.

I think you should write the same bridge

Try this:

public class someClass{
    private boolean hasDone = false;
    public void paintComponent(Graphics g){
        super.paintComponent(g);
        if(!hasDone){
            someMethod();
            hasDone = true;
        }
    }
}
