basic Java help

My assignment is to make a program that will ask for a number then multiply it by 1-12. But not allow you to continue until you give the correct answer to each problem.(ie. i pick 1. 1*1=1, 1*2=2, 1*3=3...and so on.)
I got the first part, but I can't get the last part.
I have been working on this far to long. It probley is something easy that im just looking over now. So I'm asking a second pair of eyes to look over it for me.

PHP Code:

 import javax.swing.JOptionPane;

public class addloop {
  public static void main(String[] args) {

 int number2 = 1;

      String replyString;
//this is where you pick a number and it is turned into a string
     String numberString = JOptionPane.showInputDialog(null, "enter any number");
          int number1 = Integer.parseInt(numberString);
//while loop that does all the work
      while (number1==number1) {
             for (number2=1;number2<=12;number2++){
                   String answerString = JOptionPane.showInputDialog
                ("What is " + number1 + " X " + number2 + "?");
                   int answer = Integer.parseInt(answerString);
                    if (number1 * number2 != answer){};

                                 }
                               System.exit(0);
                           }

  }
} 


Thanks

I knew it was easy, just added that in at the end before the system.exit and got it working.

PHP Code:

while (number1 * number2 != answer){ String answer2String = JOptionPane.showInputDialog(null,"Try again " +  number1 +" X " +number2 +"?");
                      int answer2= Integer.parseInt(answer2String);
                        answer = answer2;}
                        if (number1 * number2 == answer){}
