Note : This example using netbean v 7.4
Step By Step
- Create New Project Choose Java Application
- Rename Project Name to Calculator
- Delete file Calculator.java
- Add New JFrame Form under package calculator and change class Name to CalcMainUI
- Drag and drop java Swing controller into frame. Refer CalcMainUIbelow. ( Note : you can change the position of button as you like).
- Create Java class . calculateClass.java
CalcMainUI Code behind
package calculator;
