Answer

Your error tells you that there is a problem on line 211 that causes compilation to fail. That line is this:

jPanel2.setBorder(javax.swing.BorderFactory.createBevelBorder(???, java.awt.Color.red, java.awt.Color.black, java.awt.Color.blue, java.awt.Color.yellow));

You’ll notice ??? as the first argument, which is causing this compilation failure.

From the documentation the ‘???’ is in place of a type argument which should be either BevelBorder.LOWERED or BevelBorder.RAISED. So, maybe it will work if you change the above line to

jPanel2.setBorder(javax.swing.BorderFactory.createBevelBorder(BevelBorder.LOWERED, java.awt.Color.red, java.awt.Color.black, java.awt.Color.blue, java.awt.Color.yellow));
