编写基于文本的冒险游戏。我不能让我的if ==语句起作用

Question

我刚刚开始学习Java，并认为我将开始一个小项目以了解更多基本概念。当我输入诸如“ Warrior”之类的输入时，我就可以使用它，并且可以输出您选择的战士。但是，我在“ public static void Goldshire（）”中添加了第二个扫描器。然后由于某种原因它停止工作。我不太确定自己做错了什么，花了大约一个小时的时间看了一下代码，却不明白自己做了什么。如果有人能够给我一些反馈，我将不胜感激。

import java.util.Scanner;

public class Game0 {

    public static void main (String[] args) {

        characterCreation();

    }

    //Character Creation
    public static void  characterCreation(){

        @SuppressWarnings("resource")
        Scanner input = new Scanner(System.in);

        String playerName;
        byte currentHealth = 10;
        String className;

        System.out.println("Welcome to a text-based adventure game based on Zork! \n\nYou will now proceed to the naming of your character.");

        System.out.println("\nEnter your characters name: ");
        playerName = input.nextLine();
        System.out.println("Your adventure will now begin "+playerName + ".");

        System.out.println("\nYour current health is: " + currentHealth);

        System.out.println("\nYou will now choose your class:\n \n 1. Warrior\n 2. Mage\n 3. Rouge");
        className = input.nextLine();

        if(className == "Warrior") { 
            System.out.println("You have chosen Warrior.");
        }
        if (className =="Mage") {
            System.out.println("You have chosen Mage.");
        }
        if (className =="Rouge") {
            System.out.println("You have chosen Rouge.");
        }

        else {
            System.out.println("You have chosen an invalid class! The game will now end because I cannot get a loop working (:");
            //System.exit(10);
        }
    }
    //First Zone
    public static void Goldshire() {

        @SuppressWarnings("resource")
        Scanner scan2 = new Scanner(System.in);

        characterCreation();

        byte decision1;
        System.out.println("\nYou are currently at an inn in Goldshire. You can either: \n\n1. Talk to the innkeeper. \n2. Head out of the inn.");
        decision1 = scan2.nextByte();

        if(decision1==1) {
            System.out.println("You speak to the innkeeper, he tells you that a Knight outside the inn wants to speak with you. You head outside");
        }
        if(decision1 ==2) {
            System.out.println("You head outside, a Knight urgently calls you over.");
        }

        System.out.println("The Knight has a few words.");
    } 

}
