Can someone write this code for me really quick. Write a java code which acts as a calculator. I have two text fields. One where I enter in a expression and then I click the answer button and it calculates the expression and displays it in the second text field. For example I enter in 2+2-1 and it will display 3. The numbers can be two digit numbers as well I.e 22-5 and it will give 17. Also like I showed before it can be more than one operand. 2 + 2 - 1. Thanks!!
