I used the Parent and Child Window to pass the value and searched the internet for a bunch of nonsense. I felt very uncomfortable. I studied it for a long time. It turned out to be very simple. The thread is also used in this example. You don't need to be more clear. Let's just move on to the code. note how to pass the value in the ///// Dialog Box package des; import java. AWT. color;
