Thread: help the noob pls

hi guys, i just started learning Java few days ago, so as u can guess i'm struggling. i wrote a small code but for some reason it aint working:

import java.util.Scanner;
public class Noob{
static Scanner userInput= new Scanner(System.in);
public static void main(String[] args){
System.out.print("whats the shape? ");
String a= userInput.nextLine();
if(a.equals("triangle")){
System.out.print("what's the length? ");
int x= userInput.nextInt();
System.out.print("what's the width? ");
int y= userInput.nextInt();
System.out.print("what u wanna know? ");
String b= userInput.nextLine();
if(b.equals("territory")){
triTerr(x,y);
}}}
public static void triTerr(int x, int y){
x= x*y/2;
System.out.println("territory of triangle is "+ x);
}}
so as u can see it supposed to ask u the shape (triangle), then the length and the width, what u wanna know(territory) and it supposed to calculate and give u the territory of triangle. but for some reason it stuck and doesn't let u answer for "what u wanna know?"... what am i doing wrong??
thnx for any help guys, it supposed to be a realy easy one.

To fix it, put a userInput.nextLine(); after "what you wanna know?"

Sorry i don't get it....can you type it?

System.out.print("what u wanna know? ");
userInput.nextLine();
String b = userInput.nextLine();
