Switch Statement with Strings in Java

Ok, basically i want to know if this is possible and how to do it. I have a menu and i want this switch statement to recognize chars or a string that was entered by the user.

I have a little menu program that I am writing:

import java.util.*;
import java.io.*;
import java.io.File;
import java.io.FileReader;

public class Personnel
{
    // Instance Variables
    private static String empName;
    private static double wage;

    public static void main(String[] args) throws Exception
    {

        clearScreen();
        question();
        printMenu();
        exit();
    }

    public static void clearScreen()
    {
        System.out.println("\u001b[H\u001b[2J");
    }

    private static void exit()
    {
        System.exit(0);
    }

    private static void printMenu()
    {
        System.out.println("\t------------------------------------");
        System.out.println("\t|Commands: n - New employee        |");
        System.out.println("\t|          c - Compute paychecks   |");
        System.out.println("\t|          r - Raise wages         |");
        System.out.println("\t|          p - Print records       |");
        System.out.println("\t|          d - Download data       |");
        System.out.println("\t|          u - Upload data         |");
        System.out.println("\t|          q - Quit                |");
        System.out.println("\t------------------------------------");
        System.out.println("");
    }

    private static void question()
    {
        System.out.println("Enter command: ");
        Scanner q = new Scanner(System.in);
        // String input = q.nextLine();

        switch (q.nextLine())
        {
        case "n":
            System.out.println("Enter the name of new employee: ");
            Scanner stdin = new Scanner(System.in);
            System.out.println("Hourly (h) or salaried (s): ");
            Scanner stdin2 = new Scanner(System.in);
            if (stdin2.equals("h"))
            {
                System.out.println("Enter hourly wage: ");
                Scanner stdin3 = new Scanner(System.in);
            }
            else
            {
                System.out.println("Enter annual salary: ");
                Scanner stdin4 = new Scanner(System.in);
            }
            break;

        /*
         * case 9:
         *      System.out.println ("Please proceed."); 
         *      new InputMenu(); 
         *      break; 
         * default: 
         *      System.err.println ("Unrecognized option" ); break;
         */
        }
    }
}

What i am trying to do is make this menu work so that you can type in a command then i will write methods to run depending on what command was typed in. Is switch statement the best way to do this? After they enter in the info i need it to “break” back to the main menu. And anytime during the entire program, if they enter q then the program exits. I’m not sure the best way to go about doing this.

Thanks!

Using String in switch-case statements is supported in jdk 7. Please refer this link for an example: http://docs.oracle.com/javase/7/docs/technotes/guides/language/strings-switch.html

Hope this helps.
