java.lang.ClassCastException: Can not cast javax.swing.JPanel to java.lang.Boolean

I get that error when executing JFrame in which Jpanel is located. Any idea I get why this occurs would be very helpful.

The fragment of error code ...

Can not cast javax.swing.JPanel to java.lang.Boolean

tells you that you are trying to "Castear" (Convert or pass data of one type, to another type of data) in this case a JPanel (visual element) to a boolean type (true or false) Which by logic is impossible.
