q2.java

// q2.java - Calculator Program
// Write a complete Java program that acts as a simple calculator

// Your program should:
// 1. Import the Scanner class
// 2. Create a class named 'q2'
// 3. Implement the main method
// 4. Get two numbers from the user
// 5. Perform arithmetic operations and display results
// 6. Demonstrate different types of operators (arithmetic, relational, logical)

// Write your complete solution below:
