    Angry Multiple Computations in 1 file

    having an issue with creating "choice" variable. I am trying to create a program which will ask you a math problem based upon selecting the type of problem.

    Here is the program:

    import java.util.Scanner;
    public class BasicfourLoop {
    public static void main(String[] args) {
    final int NUMBER_OF_QUESTIONS = 5;
    int correctCount = 0;
    int count = 0;
    int choice;
    choice = 4;
    long startTime = System.currentTimeMillis();
    String output = " ";
    Scanner input = new Scanner(System.in);

    while (count < NUMBER_OF_QUESTIONS) {
    int number1 = (int) (Math.random() * 100);
    int number2 = (int) (Math.random() * 100);

    if (number1 < number2) {
    int temp = number1;
    number1 = number2;
    number2 = temp;
    }

    System.out.println("Enter your Choice:");
    System.out.println("Enter 1 for Addition ");
    System.out.println("Enter 2 for Subtraction ");
    System.out.println("Enter 3 for Multiplication ");
    System.out.println("Enter 4 for Division");



    System.out.print("What is " + number1 + " + " + number2 + "? ");
    int answer = input.nextInt();

    if (number1 + number2 == answer) {
    System.out.println("You are One Smart Cookie!!!");
    correctCount++;
    }
    else
    System.out.println("Your answer is stupid.\n" + number1 + " + " + number2 + " should be " + (number1 + number2));
    System.out.print("What is " + number1 + " + " + number2 + "? ");

    count++;

    output += "\n" + number1 + "+" + number2 + "=" + answer + ((number1 + number2 == answer) ? " awesome" : " idiot");
    }

    long endTime = System.currentTimeMillis();
    long testTime = endTime - startTime;
    System.out.println("Correct count is " + correctCount + "\nTest time is " + testTime / 1000 + " seconds\n" + output);
    }
    }


    Please help!!!

    Please explain what problems you are having.

    Please edit your post and wrap your code with code tags:
    [code=java]
    <YOUR CODE HERE>
    [/code]
    to get highlighting and preserve formatting.
    If you don't understand my answer, don't ignore it, ask a question.

    That is part of it. Now the code needs to be formatted.
    Nested statements need to be indented 3-4 spaces to make the code easier to read and understand.
    All statements should NOT start in the first column.

    Can you explain what problems you are having?

    Thanx so much Norm

    I would like to create a program which, when selecting one of four options, creates a math problem. After being asked 5 questions, the program would show all five problems and show how much time it took to complete the whole process.
