Code:

import java.util.*;

public class test {

	public static void main(String[] args) {
		Scanner s = new Scanner(System.in);
		prompt(s);
	}
	
	public static void prompt(Scanner s) {
		int num = 1;
		System.out.print("Write something: ");
		String something = s.nextLine();
		System.out.println(something);
		boolean test = something == "lol";
		while(test) {
			System.out.println("in the while loop" + num + " times!");
			num++;
			System.out.print("Write something: ");
			something = s.nextLine();
		}
	}
	
	
	

}

Why wont it go into the freaking while loop when i type lol! I really am so frustrated right now and can't figure out why.... Please help.

I think i figurred it out... Strings have to be compared using .equal() object

This. You cannot compare strings via ==, it's just wrong.

I believe what you are looking for is

Code:

boolean test = something.equals("lol");

OR if you want it to ignore capitals

Code:

boolean test = something.equalsIgnoreCase("lol");

Looks like you have a fundamental misunderstanding of the logical operators, primitives and the way they can and can't interact. Probably need to dedicate a little more time to reviewing that stuff, it's more important then getting up on all the different methods and utils.

It's good you were able to find some code to fix the problem, that's also an important aspect, but get the basics down too!!! And first!!!!

All that boring stuff is what lays the foundation for good OO, and that's the most important thing for anyone wanting to be a programmer.

I do know most of the fundamentals, I think?
I just never really realized Strings were an object (they are captialized "S"trings which makes them an object) this being only my second programing course yet.

Also, new problem i'm encountering

Code:

while(!(again.toLowerCase().startsWith("y")) || !(again.toLowerCase().startsWith("n"))) {
            again = playAgainPrompt(s);
        }

What im trying to do is make it so it does again = playAgainPrompt(s); if again.toLowerCase().startsWith("y") does NOT start with "y" or "n".

Thanks guys,
