Java program exit function not working

Question

i'm a newbie to java so i decided to create a simple program that prints out even numbers. I tried to make it exit a while loop if you answered no to the question but it just keeps on going.

Here's the code

public static void main(String[] args){
    String continueYorN = "Y";
    int i = 0;
    while (continueYorN.equalsIgnoreCase("y")){

        while(i >= 0){
            i++;
            if((i%2) == 0){
                System.out.println(i);
                continue;
            }
            System.out.println("Do you want to generate another even number?");
            continueYorN = userInput.nextLine();
        }
    }
}

You program gets stuck in the inner loop and never gets a chance to read user input. — Giorgio

Your loop has no break condition (i.e, something that stop the loop in some condition), so it will continue forever.

You should replace the inner while with something like that:

while(i >= 0){
        i++;
        if((i%2) == 0){
            System.out.println(i);
            break;
    }
