SwitchOperatedTextMenu Java Project

This project demonstrates a simple text-based menu in Java, where users can choose from multiple options using a switch statement. The program provides a menu, takes user input, and processes different commands accordingly. The menu allows users to choose between different menu items or quit the program.

Features

• Simple text menu with options.
• Switch-case structure for handling user choices.
• Validates user input to ensure it is a valid menu item.

How It Works

1. The program prints a menu with numbered options.
2. The user is prompted to choose a menu item (1, 2, or 0 to quit).
3. Based on the input, the corresponding case in the switch statement is executed.
4. The program continues to prompt the user until they choose to quit (option 0).

Example

1. Menu item #1
2. Menu item #2
0. Quit
Choose menu item: 1
You've chosen item #1

Code

import java.util.Scanner;

public class SwitchOperatedTextMenu {
    public static void main(String[] args) {
        Scanner in = new Scanner(System.in);
        // print menu
        for (int i = 1; i <= 2; i++)
            System.out.println(i + ". Menu item #" + i);
        System.out.println("0. Quit");
        // handle user commands
        boolean quit = false;
        int menuItem;
        do {
            System.out.print("Choose menu item: ");
            menuItem = in.nextInt();
            switch (menuItem) {
                case 1:
                    System.out.println("You've chosen item #1");
                    // do something...
                    break;
                case 2:
                    System.out.println("You've chosen item #2");
                    // do something...
                    break;
                case 0:
                    quit = true;
                    break;
                default:
                    System.out.println("Invalid choice.");
            }
        } while (!quit);
        System.out.println("Bye-bye!");
    }
}
