Again, setText(""); does not work.
It produces a loop which locks the intended functionality.
When tc.setText(""); as stated abopve is compiles it continually
clears the Text Field to the point where the program is unresponsive.
Thank you for your help though, and I will make sure to indent from
now on...

Does anyone have other expertise which may negate this looping
mechanism caused by setText("")?

Thank you very much.

You don't generally want to use "==" to test string equality, unless you
make sure that you first INTERN the strings in question.  That is the
only way you are guaranteed to get a canonical object for a given
string.

Constant strings are interned automatically, but any that you get from
user input or new string creation would not be unless you explicitly
call the intern() method.
