RockPaperScissors-Java

🪨🗞️✂️ Rock Paper Scissors Game - Java (Beginner Project)

Hi! This is a simple Rock, Paper, Scissors game I created in Java.
The game allows a human player to play against the computer (Jarvis) for 3 rounds, keeping track of scores and declaring the overall winner.

It's a fun and interactive way to practice Java basics like loops, conditionals, arrays, and user input.

🔧 How it Works

1. The game runs for 3 rounds.
2. For each round:
   • You enter your choice as a number:
     • 1 = Rock
     • 2 = Paper
     • 3 = Scissors
   • The computer randomly selects its choice.
3. The program compares your choice and the computer's:
   • If the choices are the same → it's a draw.
   • If your choice beats the computer → you win the round.
   • Otherwise → computer wins the round.
4. Scores are updated after each round.
5. After 3 rounds, the program displays:
   • Total score for you
   • Total score for Jarvis
   • Number of draws
   • Overall winner

🧠 What I Practiced in This Project

• Using arrays to store options (Rock, Paper, Scissors).
• Loops (for loop) for multiple rounds.
• Random number generation for computer choice.
• Input validation using while loops.
• Conditionals (if-else) to determine round winner.
• Formatted output using System.out.println.
