1. What is the Java Swing Calculator?

The Java Swing Calculator is a graphical user interface application that performs basic arithmetic operations. It follows the principle: Result = Operand1 Operator Operand2, where the operator can be addition (+), subtraction (-), multiplication (*), or division (/).

2. How Does the Calculator Work?

The calculator uses the basic arithmetic formula:

Where:

• \( Operand1 \) — First numerical input
• \( Operand2 \) — Second numerical input
• \( Operator \) — Mathematical operation (+, -, *, /)

Explanation: The calculator takes two numerical inputs and performs the selected arithmetic operation, displaying the result.

3. Importance of Arithmetic Operations

Details: Basic arithmetic operations are fundamental to all computing tasks. This calculator demonstrates how to implement these operations in a Java Swing application.

4. Using the Calculator

Tips: Enter numerical values for both operands, select an operator, and click Calculate. For division, ensure the second operand is not zero.

5. Frequently Asked Questions (FAQ)

Q1: What is Java Swing?
A: Java Swing is a GUI widget toolkit for Java that provides components for building graphical user interfaces.

Q2: What operations does this calculator support?
A: It supports basic arithmetic operations: addition, subtraction, multiplication, and division.

Q3: How does it handle division by zero?
A: The calculator will display "Undefined (division by zero)" if you attempt to divide by zero.

Q4: Can I use decimal numbers?
A: Yes, the calculator accepts and processes decimal numbers with up to 4 decimal places.

Q5: How would this be implemented in Java Swing?
A: In Java Swing, you would create JTextField for inputs, JComboBox for operator selection, JButton for calculation, and JLabel to display the result.
