Calculator

• This applet looks best in Netscape Navigator 4.5.
• I decided to implement the calculator applet for this assignment.
• The problem was to design a calculator that could perform addition on two integers that a user enters, and return that result in a TextField ( using the AWT ) on the visible applet.
• The calculator I implemented can perform addition, subtraction, multiplication, and division.
• Division by zero is not allowed.
• Only one operation can be performed at a time. For instance, if you add two numbers, and then you wish to subtract two other numbers you must first hit clear.
• After performing one operation, you cannot use the result in the next operation without hitting clear first and then reentering the result.
• I could have implemented the calculator to allow for this manipulation, but that would have made it exceedingly more difficult than the desired assignment.
• Using a combination of BorderLayout and GridLayout, I set up the design of the calculator.
• Using actionPerformed, I handled each case of operation, as well as the clear and equals buttons.
