There's also the subFlag condition (and ideally using the equals method 
for comparison as mentioned in <jsd9cf$hha$1@dont-email.me>), but 
another, significant problem is to do with your program's logic as you 
don't reset the state of the String, strng1, or output the computed value.

After an addition or subtraction operation, you need to reset your 
string so that you start building the next operand, not a concatenation 
of the first /and/ second operands. You also need to set the JTextField 
text to the (type-converted) value of operand1 when requesting the total.

Kind regards,
Mike
