Design Comment)
1. I've intentionally put actionPerformed method
inside Constructor, because I had seen many examples like this way.
Is it all right ?
2.

In the above method, I tried to read data1 or data2 by jComboBox2 and uesd getSelectedIndex()
method to count array (data[][])index.
I wonder if I successfully implemented.
Sincerely.
p.s ;
I feel sorry because I cross posted this message.

Don't get me started about those stupid light bulbs.
