Logical Calculator

This is a simple logical calculator implemented in Java using Swing for the GUI.

Features

  • Basic arithmetic operations: addition, subtraction, multiplication, division, and modulus.
  • Logical operations: AND, OR, XOR, NOT, NAND, NOR.
  • Radix conversion: Decimal, Binary, Hexadecimal.
  • Input and output in the specified radix.

Code Structure

The calculator is implemented as a Swing GUI application with the following key components:

  • Main Class: Calculator
  • GUI Components:
    • JTextField for displaying the current input/result.
    • JLabel for displaying the expression.
    • JButtons for numeric input, arithmetic/logical operations, and other functionalities.
    • JRadioButtons for selecting the radix (Decimal, Binary, Hexadecimal).
    • JPanel for organizing buttons in a grid layout.

Usage

  1. Run the application.
  2. Input numeric values and perform arithmetic or logical operations.
  3. Select the desired radix for input and output.

How to Use

  1. Numeric Input:

    • Use numeric buttons (0-9) and alphabetic buttons (A-F in hexadecimal mode).
    • Decimal point (.) is available for floating-point numbers.

  2. Arithmetic Operations:

    • Addition (+), Subtraction (-), Multiplication (*), Division (/), Modulus (%).
    • Change sign (+/-).

  3. Logical Operations:

    • AND (AND), OR (OR), XOR (XOR), NOT (NOT), NAND (NAND), NOR (NOR).

  4. Other Functions:

    • Clear Entry (CE): Clears the current input.
    • Delete (DEL): Removes the last character from the input.
    • Equals (=): Calculates and displays the result.

  5. Radix Selection:

    • Use radio buttons to switch between Decimal, Binary, and Hexadecimal input and output.

Example

Decimal Input:     Binary Output:
1 + 1 = 2           1 + 1 = 10
3 AND 1 = 1         11 AND 01 = 01

Dependencies

  • Java Swing
