Bluej Java - Quiz Help!!!

[Harblkipz]

Hey, I'm making a quiz in Bluej and I need help because I can't figure out how to change a input string into a int value. I have this half in terminal and half in dialogue boxes, if you can help make it all in dialogue boxes that will be helpful too. I have to put in 25 questions. I thank you in advance for your help. By the way, I used Hacker Dan's TUT for Swing for this. Not my oringinal work completely.

Here's my code.

code:

import javax.swing.*;    //import line to load the libray/package that import java.io.*;                         //has the swing GUI components. public class SwifhgfjfjdngGUI {                     public static void main(String[] args)     {            int x1,score;    x1=0;    score = 0;                   //This is the code to disply the msg box.         //JOptionPane.showMessageDialog(null, "This quiz is about Java, I hope you're prepared.", "JavaQuiz!", JOptionPane.WARNING_MESSAGE);         //The 1st argument for the dialog is for a parent component, when no parent component is used you put it as null         //The last argument is for the icon to be displayed with the dialog.         //Thess are the comanan icons used in Java:         //WARNING_MESSAGE         //ERROR_MESSAGE         //INFORMATION_MESSAGE         //PLAIN_MESSAGE         //QUESTION_MESSAGE                 /*Note: JOptionPane.showMessageDialog can be shorted to*/ JOptionPane.showMessageDialog(null,"This quiz is about Java, I hope you're prepared.");         //if no title or icon setings are whonted or needed.                 System.out.println("A. What is the library you import into Java,uasually, at the begining of the Program?");         System.out.println("1) java.oi.#");         System.out.println("2) java.io.&");         System.out.println("3) java.io.*");         System.out.println("4) java.io.#");             String uInput; //a varibale to store the users input                 //the JOptionPane.showInputDialog fuction returns a string of the users input         uInput = JOptionPane.showInputDialog(null, "Type your answer here.(1, 2, 3, or 4)", "Answer Box", JOptionPane.ERROR_MESSAGE);         //As with the msg Dialog the 1st argument is for a parent component and the last for         //an icon to go with the dialog. (see posable icons under msg dialog)         //The JOptionPane.showInputDialog fuction can be shortend to JOptionPane.showInputDialog("msg to show user")         //if no other arrments are needed.         //If the user hits Cancel insted of OK the return value will be null                 //Note: the string responce can be conveted to an other tpye if need         //i may add how to do this in an update of this tutorale latter.                 //uInput=Integer.parseInt(x1);                 if (uInput == 1)         {             score = score+0;                     }         else if (uInput == 2)         {             score = score+0;         }         else if (uInput == 3)         {             score = score+1;         }          else if (uInput == 4)         {             score = score+0;         }                 System.out.println(" ");         System.out.println("Next Question");         System.out.println(" ");             } }

It has some bad code sorry about that. Thanks!

with java 1.6:

code:

uInput=Integer.parseInt(x1); //this is wrong x1=Integer.parseInt(uInput); //this is right //hereafter, use x1 for comparison. You might also consider telling the user if they've used an invalid value(using a try/catch statement & JOptionPanel)

Thanks a lot! That literally solved my biggest problem with this code.
