posted the new code. i want to display two rectangles as per the code.

HI Norm ,

Yes the first rectangle getting hide and another one is displaying for which i have used the different coordinates.

Output.jpg

sent you the screenshot

shridhar java.awt.Rectangle[x=0,y=0,width=624,height=444]

This is what i am getting on console after putting your statement in paintComponent function.

with the help of this FlowLayout both of the rectangles gone..... Nothing is there on frame now.
Can you please help me in compiling this at your end and help me in correcting the code if possible for you please.
