Creating a simple calculator in Java with UI labels can be done efficiently using Swing for a modern look or AWT for a lightweight approach. Below is an example using Java Swing with labels and buttons to perform basic arithmetic operations.
Steps to Build
1. Setup the Frame and Components
Use JFrame as the main window.
Add a JLabel or JTextField to display input/output.
Create JButton components for digits, operators, and control actions (C, =).
2. Layout Management
Use JPanel with GridLayout for buttons.
Place the display label at the top using BorderLayout.NORTH.
3. Event Handling
Implement ActionListener to capture button clicks.
Store operands and operator, then compute results when "=" is pressed.
