panel's size is also very big its,17040 pixel...what should i have to do avoid flickering

Answer 1

My crystalball tells me that you are painting the entire screen with each call to paint and your are also making a call to super.paintComponent(g) when you do so... hence much flickering exists with your application even though it's double buffered.
To avoid this problem do the following:
take 3 whole slottered chickens, put them in a bag and ... oh that was for array problems... let me see for flickering....
Well, you need to do offscreen rendering to an image and call repaint when done, but in your paintComponent(Graphics g) do this:
public void paintComponent(Graphics g){
  drawImage(myOffscreenImage4Rendering, 0, 0, this); //notice 1 liner--no other code needed or wanted here.
}I do this with 1600x1200 on an AMD 2GHz with 500+ objects being drawn and no flicker. I've had up to 10,000 objects with no flicker, but yes, the animation speed was severely impacted due to the number of objects being rendered each cycle.
