    Default 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.

    EDIT: I realized that you are leaving the newline character in the buffer.

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

    sorry i missed ur answer, thnx. but i i didn't have to use "userInput.nextLine();" when dealing with String a, int x and int y, why do i have to use it with String b???
