Thread: runs once only

well idk what was wrong , but when i was messing around with the code i some how fixed it . i also changed how u have the select taxi number . cause when i first ran though it w/o really reading it , i put a name were it needed the number and just blew up XP , so its now a little different

package test;
 
//This program will provide a menu system for inputting
//data regards 3 taxi's
import java.util.Scanner;//importing the scanner utility
 
public class c22taxis {
	static int preference;
	static Scanner input = new Scanner(System.in);
	static String[] name = new String[3];
	static String[] dest = new String[3];
	static int tNo = 0;
 
	public static void main(String[] args) {
		menu();// calling the method /main menu
	}
 
	public static void menu(){
 
		// printing of the system menu on screen to user
		System.out.println("Welcome to C22 Taxis automated System");
		System.out.println("");// blank line
		System.out.println("Please select from a option below to continue.");
		System.out.println("");// blank line
		System.out.println(" 1. Enter/Change Driver Name.");
		System.out.println("");// blank line
		System.out.println(" 2. Enter/Change veichle booking status.");
		System.out.println("");// blank line
		System.out.println(" 3. Enter/Change veichle service status.");
		System.out.println("");// blank line
		System.out.println(" 4. List all veichle status");
		System.out.println("");// blank line
		System.out.println(" 5. Exit");// exit command for program
		System.out.println("");
		System.out.print("Please select a option: ");
		mainAsk();
	}
	public static void mainAsk(){
		preference = input.nextInt();
 
		if (preference == 1)// path of input from user
		{
			System.out.println('\f');
			// sub menu for driver change details
			System.out.println(" Driver name sub Menu");
			System.out.println("");
			System.out.println("");
			System.out.print("Please enter taxi number: ");
 
			String tNo2 = input.next();    // Changed so that if some1 puts in a non-int 
			if (tNo2.contains("1") || tNo2.contains("2") || tNo2.contains("3")){
				tNo = Integer.parseInt(tNo2);
			} else {
				tNo = 0;
			}
 
			switch (tNo) {
			case 1:
				System.out.print("Please enter drivers name: ");
				name[0] = input.next();
				break;
			case 2:
				System.out.print("Please enter drivers name: ");
				name[1] = input.next();
				break;
 
			case 3:
				System.out.print("Please enter drivers name: ");
				name[2] = input.next();
				break;
 
			// the default
			default:
				System.out.print("invalid entry return to menu.");
				break;
			}
			menu();
		} else if (preference == 2) {
			System.out.println('\f');
			// sub menu start for taxi status
			System.out.println(" Taxi status sub Menu");
			System.out.println("");
			System.out.println("");
			System.out.print("Please enter taxi number: ");
 
			String tNo2 = input.next();    // Changed so that if some1 puts in a non-int 
			if (tNo2.contains("1") || tNo2.contains("2") || tNo2.contains("3")){
				tNo = Integer.parseInt(tNo2);
			} else {
				tNo = 0;
			}
 
			if (tNo == 1) {
				System.out
						.print("Please enter taxi1 destination(if no destination enter NONE): ");
				dest[0] = input.next();
			} else if (tNo == 2) {
				System.out
						.print("Please enter taxi2 destination(if no destination enter NONE): ");
				dest[1] = input.next();
			} else if (tNo == 3) {
				System.out
						.print("Please enter taxi3 destination(if no destination enter NONE): ");
				dest[2] = input.next();
			} // else instruction at end giving invalid input for anything other
			else
				System.out.println("Invalid entry please restart");
				menu();
		}
 
		else
			System.out.println("end program");
			System.exit(0);
	}
}

i only changed a few things , but some things i would change if i hadn't got it to work so easily was change the long if else on the main menu to a case , and have each case call a method for it .

switch (preference) {
   case 1:
      this.changeName();
   ....
}
 
private void changeName(){
    the actions to change the name 
}

also , in future posts , please use the code tags . the button to auto add them is # ,then just paste the code between them
