Java Calculator Collection

This repository contains simple calculator programs written in Java. The calculators can perform basic arithmetic operations such as addition, subtraction, multiplication, and division. The current implementations use else if statements and switch cases to handle different arithmetic modes. More features and modes may be added in the future.

Features

• Addition: Adds two numbers.
• Subtraction: Subtracts the second number from the first number.
• Multiplication: Multiplies two numbers.
• Division: Divides the first number by the second number. Includes a check to prevent division by zero.

Programs

1. Switch Calculator (switch_calculator.java): Uses a switch statement to handle the selection of arithmetic operations.

2. Else If Calculator (Calculator_ElseIf.java): Uses else if statements to handle the selection of arithmetic operations.

3. Ternary Calculator (TernaryCalculator.java): Uses a nested ternary operator to perform arithmetic operations in a compact, single-line expression.

4. Function Calculator (Function_Calculator.java): Uses functions to handle the selection of arithmetic operations.

5. Birthday Calculator (Whats_my_birthday.java): Calculates a person's age and the number of days until their next birthday based on their birth date and the current date.
