创了一个类，请问两个不同方法怎么比较对象

import java.util.Scanner;
public class 游戏库 {
    public static void main(String[] args) {
        Scanner scan=new Scanner(System.in);
        do {
            System.out.println("已打开游戏库，按v进入下载页面，按q进入游戏卸载页面");
            switch (scan.next().charAt(0)) {
                case 'v':
                    System.out.println("已进入下载页面");
                    do {
                        System.out.println("请输入要添加的游戏名称");
                        games game1=new games(scan.next());
                        game1.add();
                        System.out.println("是否继续添加？y/n");
                    }while (scan.next().equals("y"));
                    break;
                case 'q':
                    do {
                        System.out.println("已进入游戏卸载页面");
                        System.out.println("请输入要卸载的游戏");
                        games game2=new games(scan.next());
                        game2.reduce();

                default:}
