If Statement not Running after the condition was meet [duplicate]

I'm working on a basic game and want to use if statements to make it a bit more fun, but when a condition was meet (Ex. Choosing something in a menu) the if statement still wouldn't run.

This is for a basic game made in Java and using a basic text-based game engine that I made. I've tried checking if it would break out of the while loop if the condition was met. But it still didn't break out of my while loop.

public class App 
{
    public static void bossFight() {
        int Health = 100;
        int bossHealth = 200;

        while(Health > 0) {

            System.out.println("Health: " + Health);
            System.out.println("Boss's Health: " + bossHealth);


            Scanner scan2 = new Scanner(System.in);
            System.out.println("Attacks: ");
            System.out.println("1. Attack with bow \n 2. Slice with Sword \n 3. Magic");

            String attackChoice = scan2.next();

            if ( attackChoice == "1" ) 
            {

                bossHealth--;
            }

            if(bossHealth < 0) {
                System.out.println("Yeah you beat the boss!");
                break;
            }

I expect it to lower the boss's health but it just skipped the statement and ran the loop again. When I tried to break the if statement with break; it still didn't break.
