Outer class jframe is not hiding when calling the inner class jframe
- by user2909960
When i am calling the inner jframe, it is called, but outer jframe is not hiding. instead it gets overlapped. so what will be the solution for this.
Is there any way to get out of this. As i tried when i am calling the inner class frame, the outer class frame is also called, and it is not hidden.
