JAVA面试题:判断两个值相同(不用equals)

import java.util.Scanner;


public class IsEqualsTest {


    static String x1;
    static String x2;
    public static void main(String[] args) throws ClassNotFoundException {
        // TODO 自动生成方法存根
        do {
            Scanner in = new Scanner(System.in);
            System.out.println("请输入一个原始值：");

            x1 = in.nextLine();
            //System.out.println(x1);
            System.out.println("请输入一个对比值：");
            x2 = in.nextLine();
            System.out.println("开始测试" + x1 + "和" + x2 + "是否相同");
            if (new IsEqualsTest().Myequals(x2)) {
                System.out.println("相同!");
            } else {
                System.out.println("不相等，请重新输入！");
            }
        } while (!new IsEqualsTest().Myequals(x2));

    }

    public boolean Myequals(String X2) {
        if (x1.hashCode() == X2.hashCode()) {
            return true;
        } else {
            return false;
        }
    }
}
