    import java.util.Random;
    import javax.swing.JOptionPane;

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

    //Declare
    Random generator = new Random();
    int num1;
    int num2;
    int answer;
    int guess1;
    String choice;
    boolean shouldLoopEnd = false;//boolean variable to determine if the loop should end

    //Input
    num1 = generator.nextInt(50); //Gets random num1
    num2 = generator.nextInt(50); //Gets Random num2

    //infinite loop begins...
    while (true)

    shouldLoopEnd = true;}

    if(shouldLoopEnd == true)
    { //Begin if bracket

    Hi Swiper.
    Firstly, please don't emphasise urgency in your thread names, your thread is no more important than anyone else's so stick to informative titles instead.
    Secondly, always surround your code in tags such as the ones found in my signature.
    And lastly, all you need to do is move
    num1 = generator.nextInt(50); //Gets random num1
    num2 = generator.nextInt(50); //Gets Random num2
    inside your while loop, and remove break from inside the winning if statement.

    Then add shouldLoopEnd = false; to the start of the while loop
    Move the number generation into the winning If statement.

    Move the number generation into the winning If statement.
    into the winning If statement
    winning If statement
    Initialise the original numbers before the while loop, then if the person guesses correctly, generate new numbers in the if block.
