Java program Calculator,help Please!?
i'm trying to build a calculator with the basic operations ( +, -, * ,/) and the root square as well as the decimal point
but when clicking on the form on the root square or the decimal point they're still not working as if it's concatenating the numbers although i did parse them
and i'm trying to do any operation for more than just 2 inputs and something is still wrong it also seems that the numbers or actually certain numbers are being concatenated instead of applying the operation on
so can you please help me?
thanks !

Your SqrtActionPerformed() method has a bad String append value. And, I'm not quite sure what your Equals action listener is trying to do. By the time you click equals, you should have a value assigned to input1 and input2, so there should be no double parsing. Double parsing should only be happening when a number is clicked.
