    Default Easy game not doing what i want it to... Boo

    This is my second attempt at running a program through the terminal. I finally found out how to change it to plain text so that i can add the .java extension and find it. It compiles and runs but doesn't quite do what i want. It detects if the number is too high or too low just fine. But when the correct number is guessed the command line just prints a "new" empty line when it should be saying "ding ding ding".

    I have tried getting rid of the random number and assigning a set field, 77 for example. It still does not ding for me once the two are equal. I have also tried rearranging my if/else statements to try to get it to work. This simple game is making me != happy. Please point me in the right direction!!!

    import java.util.Random;
    import java.util.Scanner;
    class UserGuess {
    	public static void main(String[] args) {
    	Random num = new Random();
    	Scanner input = new Scanner(System.in);
    	int winningNum = num.nextInt(100);
    	int userGuess;
    	System.out.println("Enter a number between 1 and 100");
    	userGuess = input.nextInt();
    	while (userGuess != winningNum){
    	if (userGuess == winningNum){
    	System.out.println("ding ding ding");
    	} else if (userGuess > winningNum) {
    	System.out.println("too high");
    	userGuess = input.nextInt();
    	} else {
    	System.out.println("too low");
    	userGuess = input.nextInt();

    It might help you if you can trace your program using a paper and pencil. Run your program and simultaneously trace it on the paper.
    You will end up knowing where exactly you are making mistake.
    You can even add some System.out.println() statements to monitor your execution.
    Try first to your level best. If you still fail then we shall help you more.
    Hint: Know the flow of control for loops and conditional statements.
