Java 如何重置到代码中的某个点

我只想在那里再做一次陈述，最后一次 显然是语法错误，应该删除。 这是一个语法错误吗？我错过什么了吗？ 拜托，我是新手，不熟练。

在Java中（a | | |（b | | | c））可以编写（a | | b | | | c），这避免了代码所遇到的括号问题

但如果让我猜。。。是这条线

import java.util.Scanner;

public class playerinput {

    private static final String  = null;
    private static Scanner user_input;

    public static void main(String[] args) {
        user_input = new Scanner (System.in);
        String firstName;
        System.out.print("Enter your name here:");
        firstName = user_input.next();
        String lastName;
        System.out.print("Ok cool, and your last?:");
        lastName = user_input.next();
        String thankYou;
        thankYou = "Alright," + ' ' + firstName + ' ' + lastName + ',' + ' '
         + "that's all we'll need. Have a nice day, and thank you again.";      
        System.out.println(thankYou);   
        System.out.println("Oh, one more question,");
        System.out.println("if you don't mind.");
        String Response = user_input.next();
        if (Response.equals("Yea?")||(Response.equals("Yes?")
                ||(Response.equals("Sure")))){
            System.out.println("How old are you, sir?");
        }
        else {
            System.out.println("That's not the answer");
            System.out.println("im looking for...");
            System.out.println("Please, reconsider.");
            String Response2 = user_input.next();
            if (Response2.equals("Fine")||(Response2.equals("Yea")||(Response2.equals("Yes")
                    ||(Response2.equals("Sure")||(Response2.equals("I guess")
                    ||(Response2.equals("I suppose"))))))){{
                System.out.println("Good, let us procede.");
                System.out.println("How old are you?");
                String Response3 = user_input.next();
            }
            else {
                System.out.println("Fine then, be that way.");
                break;
            }
        }   
    }
}

看起来末端多余的大括号是不必要的。

正确缩进代码作为开始。如果

语句
цццц），则一个
有两个括号。）{{
看起来有点像……仔细检查你的大括号。还有，为什么在你只使用条件OR运算符的情况下在if语句中使用这么多括号呢？Eclipse让我这样做的原因是括号太少了，并试图正确地跟随大括号之类的东西？
     if (Response2.equals("Fine")||(Response2.equals("Yea")(Response2.equals("Yes")
                ||(Response2.equals("Sure")||(Response2.equals("I guess")
                ||(Response2.equals("I suppose"))))))){{
