Hello All

I am writing this program which:
- generates two random numbers
-ask user to multiply them
-checked users answer to see if its correct.
- if not correct, asked the user to guess again

I have everything working except the loop that is needed to have the user continue to guess if inputing the wrong answer.

As it stands right now, if the user answers correct, get a message saying "you answered correct.

If user is wrong, gets message saying "Guess Again". I need to figure out how to have the program loop back around to have user input a new answer until user gets it right


import java.io.*;
import java.util.Random;
public class math
{
//-----------------------------------------------------------------
// Generates random numbers
//-----------------------------------------------------------------
public static void main (String[] args)throws IOException
{
DataInputStream stdin = new DataInputStream (System.in);
Random generator = new Random();
int num1;
int num2;
int guess;
int answer;
String string1;

num1 = generator.nextInt(13); //Gets random num1

num2 = generator.nextInt(13); //Gets Random num2

System.out.println ("what is " + num1 + "*" + num2);


string1 = stdin.readLine();
guess = Integer.parseInt(string1);
answer = (num1 * num2);



if (guess == answer)
{ //Begin if bracket
System.out.println("Very good, the correct answer is " + answer);
} //End if Bracket
else
{ //Begin Else Brakcets
System.out.println("Guess again");
}
//End Else brackets
}

} //Close MAIN bracket


} //Close CLASS MATH bracket
