Checking a string var to an actually string?

[DoubleElite]

So, I made a random number generator/guessing game just for fun and practice. But I'm stuck.. at the end of the program if you guessed wrong it asks you if you want to try again. I have a string var and I'm trying to check if it is equal to the word "Yes", and if it is then run the program again. But it always does the else statement of the if function, even if I type the word yes.

import java.util.Scanner;


public class RandomNumber {
	//Yes, No Vars
	public String yesVar = "Yes";
	public String noVar = "No";
	//User Input
	Scanner scanner = new Scanner(System.in);
	//Try again variables 
	public boolean playAgain = false;
	public String startOverAnswer;
	
	public void pickNumber() {
		//Random Number
		int number = (int) (Math.random()*10)+1;
		//Get user guess and parse the guess to an int
		System.out.print("Your guess: ");
		String guess = scanner.nextLine();
		int guessFinal = Integer.parseInt(guess);
		
		//Check guess
		if(guessFinal == number) {
			System.out.println("Nice guess, you got it RIGHT!");
		} else {
			System.out.println("I know, it's hard. But you got it WRONG!");
			System.out.println("");
			System.out.println("Would you like to try again? (Yes or No): ");
			
			String startOverAnswer = scanner.nextLine();
			
		//Start over?	
		if(startOverAnswer == "Yes"){
			pickNumber();
		}
		    System.out.println("Ended");
		}
		
	}
}

EDIT: I figured out I need to use ".equals(object)" to compare the contents of my String.
There's also a class that runs the file, but I guess you guys don't need that code.

Read my reply in above thread.

Just read the edit. Glad you worked it out.
