解决方案
希望这对您有帮助:
任何事情之前:
单击面板1按钮_后:
当取消定义包含Panel 1的任务栏中JFrame的第二个图标时:
更新
新代码还具有最大化功能:
在按面板3上的
|-|按钮后在最大化的
panel 3上按_按钮后的面板3:

Why i am getting the errors in the abstract class.Earlier i thought there may be a class of the same so i have created a new package and created a class test but still i am getting the same error.Any Solutions to it.

解决方案
Hope this will help you with the idea:
Before anything:
After Panel 1 button _ is clicked:
When 2nd icon of JFrame in taskbar which contains Panel 1 is deiconified:
UPDATE
New code also has maximize function:
after pressing |-| button on panel 3:
after pressing _ button on maximized panel 3
panel 3:
