Python type() Function

When learning Python, you will work with different types of data, such as numbers, text, decimal values, and Boolean values. Python provides several built-in functions to help you work with these data types. One of the most useful functions is the type() function . The type() function tells you the data type of a value or variable. It helps you understand what kind of data Python is working with and can make debugging your programs easier. For example, consider these variables: age = 20 price = 99.50 name = "Rahul" is_student = True Although all four variables store data, their data types are different. Python allows us to check these types using type() . Let's understand how it works with simple examples. 1. What Is the type() Function in Python? The type() function is a built-in Python function that returns information about the type of an object. In beginner-level programming, you can use it to check whether a value is an integer, a floating-point number, a string,...

Java Program: Simple Calculator

 Here’s a Java program for a simple calculator. 

It performs addition, subtraction, multiplication, and division using switch-case and user input.

🧮 Java Program: Simple Calculator

import java.util.Scanner;

public class SimpleCalculator {
    public static void main(String[] args) {
        Scanner sc = new Scanner(System.in);

        // Display menu
        System.out.println("=== Simple Calculator ===");
        System.out.print("Enter first number: ");
        double num1 = sc.nextDouble();

        System.out.print("Enter second number: ");
        double num2 = sc.nextDouble();

        // Show operation choices
        System.out.println("\nChoose an operation:");
        System.out.println("1. Addition (+)");
        System.out.println("2. Subtraction (-)");
        System.out.println("3. Multiplication (*)");
        System.out.println("4. Division (/)");

        System.out.print("Enter your choice (1-4): ");
        int choice = sc.nextInt();

        double result;

        // Perform calculation
        switch (choice) {
            case 1:
                result = num1 + num2;
                System.out.println("Result: " + result);
                break;
            case 2:
                result = num1 - num2;
                System.out.println("Result: " + result);
                break;
            case 3:
                result = num1 * num2;
                System.out.println("Result: " + result);
                break;
            case 4:
                if (num2 != 0) {
                    result = num1 / num2;
                    System.out.println("Result: " + result);
                } else {
                    System.out.println("Error! Division by zero is not allowed.");
                }
                break;
            default:
                System.out.println("Invalid choice! Please select 1–4.");
        }

        sc.close();
    }
}

📝 Explanation

  1. Scanner class is used to take input from the user.

  2. The user enters two numbers and selects an operation.

  3. Switch-case executes the correct arithmetic operation.

  4. A check prevents division by zero.

  5. Finally, the result is displayed on the console.

✅ Sample Output

=== Simple Calculator ===
Enter first number: 15
Enter second number: 5

Choose an operation:
1. Addition (+)
2. Subtraction (-)
3. Multiplication (*)
4. Division (/)
Enter your choice (1-4): 4

Result: 3.0

Understanding Comments in Java: A Beginner’s Guide

When learning Java programming, one of the first concepts you’ll come across is comments . Comments may not affect how a program runs, but they play a crucial role in making code more understandable, readable, and maintainable. Let’s dive deeper into what comments are, why they’re important, and the different types of comments in Java. What are Comments in Java? A comment in Java is a piece of text written within a program that is ignored by the compiler . In other words, comments are notes for humans, not instructions for machines. They help developers explain the purpose of code, describe logic, or temporarily disable certain lines of code without deleting them. Why are Comments Important? 📌 Readability – Comments make code easier to understand for you and others. 📌 Maintenance – When you revisit your code after months, comments remind you what you were doing. 📌 Collaboration – In team projects, comments explain code to fellow developers. 📌 Debugging – You c...

Java Program to Check Voting Eligibility

In this program, we’ll take the user’s age as input and check whether the person is eligible to vote or not. In India, the minimum age required to vote is 18 years . 💻 Program Code // Java Program to Check Voting Eligibility import java.util.Scanner; public class VotingEligibility { public static void main(String[] args) { // Create Scanner object to take input from user Scanner sc = new Scanner(System.in); // Ask user to enter age System.out.print("Enter your age: "); int age = sc.nextInt(); // Check eligibility if (age >= 18) { System.out.println("You are eligible to vote."); } else { System.out.println("You are not eligible to vote yet."); System.out.println("You can vote after " + (18 - age) + " year(s)."); } sc.close(); // Close the scanner } } 🧠 Explanation import java.util.Scanner; → Imp...
