Calculator Lab In JAVA jGrasp

Objective:

To understand GUI components and layout managers.

Part 1 Design the Calculator Interface

Design the interface for a simple four function calculator. Think about the different components that make up the interface and the layout managers you will need to use to achieve the desired look. Dont forget about the components that you cant see in the picture. Be creative. Customize the look of your calculator by changing the colors of the buttons, the font, or add images to the buttons.

Specification

Write 2 classes:

CalculatorDriver.java

This file should contain the main method and create the frame for your calculator. Remember to add the calculator panel to the frame and make your frame visible.

CalculatorPanel.java

Create CalculatorPanel to be a subclass of JPanel. Define each component that makes up the interface as an instance variable.

The constructor should create each component, set the appropriate layout managers, and customize any components (color, font, size, etc) .

Dont worry about getting the buttons to work yet. You are simply designing the interface.

Testing

Be sure to test resizing the frame of your calculator. How does resizing the frame affect the layout of your interface?

Part 2- Make your calculator functional. Get your 4 basic math operation buttons (+, -, x, /) to work like a real calculator. Think about how many listeners you need. You should add a clear button to your calculator.
