README: Calculator Project

Purpose

This project is a simple calculator implemented in Java. It demonstrates basic input/output operations using the Scanner class, conditional statements for decision-making, and logical operators for evaluating expressions.

Learning Objectives

• Input/Output Operations:
  • Using the Scanner class to read user input from the console.
  • Formatting output using string concatenation and placeholders.
• Conditional Statements:
  • Employing if-else statements to make decisions based on conditions.
  • Utilizing nested if-else statements for more complex logic.
• Logical Operators:
  • Applying logical operators (AND, OR, NOT) to combine conditions.
  • Understanding the precedence of logical operators.

Usage

1. Compile the code:

   • Open a terminal or command prompt.
   • Navigate to the directory where the Java source code file (Calculator.java) is located.
   • Use the following command to compile the code:

     javac Calculator.java

2. Run the program:

   • Execute the compiled class file:

     java Calculator

   • The program will prompt you to enter two numbers and an operation.
   • Enter the desired values and the program will display the result.

Code Structure

The Calculator.java file contains the following:

• Import statement: Imports the Scanner class from the java.util package.
• Main method:
  • Creates a Scanner object to read user input.
  • Prompts the user to enter two numbers and an operation.
  • Uses conditional statements to determine the appropriate calculation based on the user's input.
  • Displays the result.

Additional Notes

• Error handling: Consider adding error handling to validate user input and handle invalid operations.
• Enhancements: You can extend this project by adding more operations, implementing a user-friendly interface, or using a loop to allow for multiple calculations.
• Learning resources: Refer to Java tutorials and documentation for further exploration of input/output, conditional statements, and logical operators.

By completing this project, you will have gained a solid understanding of fundamental Java concepts and be well-prepared to tackle more complex programming tasks.
