🔢 1. Number Guessing Game

🎯 Difficulty: Easy
🧠 Concepts: Random numbers, loops, if/else, Scanner

What it does:
The program picks a random number (like 1–100), and the user tries to guess it.

Random rand = new Random();

int number = rand.nextInt(100) + 1;

Add features like:

• Limiting guesses

• Telling the user “higher” or “lower”

• Counting attempts

🔐 2. Password Login System

🎯 Difficulty: Easy – Medium
🧠 Concepts: Strings, conditionals, loops

What it does:
Asks the user for a username and password. If it matches your saved values, they "log in."

if (username.equals("admin") && password.equals("1234")) {
    System.out.println("Access granted");
}


🧮 3. Simple Calculator
🎯 Difficulty: Medium

🧠 Concepts: Switch case, Scanner, methods
What it does:

Lets the user choose +, −, ×, ÷ and enter numbers.

switch (operator) {
    case '+': result = num1 + num2; break;
}

Level it up:
    Make it loop until the user quits
    Use method like add(), subtract() etc.
