Question

我没有得到什么错误，如果有人向我解释它以便我（或你）可以解决它将会很有帮助。

我的许多程序一直出现的错误是：

文件：F：\ Java Work \ Classexample3.java [line：40]
错误：解析时到达文件末尾

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;

public class Classexample3 {
    public static void main(String[] args) throws IOException {
        BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
        String answer;
        System.out.println("What kind of beverage do you want? (hot or cold)");
        answer = br.readline();

        if (answer.equals("hot")) {
            System.out.println("Please choose an item from the list below:");
            System.out.println("- tea \n- coffee");
            answer = br.readline();

            if (answer.equals("tea")) {
                System.out.println("You have purchased a hot tea:");
            } else if (answer.equals("coffee")) {
                System.out.println("You have purchased a hot coffee");
                answer = br.readline();
            }
        } else if (answer.equals("cold")) {
            System.out.println("Please choose an item from the list below:");
            System.out.println("- bubble tea \n- pop");
            answer = br.readline();
            if (answer.equal("bubble tea")) {
                System.out.println("You have purchased a cold bubble tea");
            } else if (answer.equals("pop")) {
                System.out.println("You have purchased a cold pop");
            } else {
                System.out.println("This item is not on the list");
            }
        }
    }

Answer 1

你最后错过}来关闭课程。

Answer 2

您错过了}来关闭相应的public class Classexample3 {。错误与它所声明的完全相同 - Java编译器期望在某些时候关闭类声明，但文件结束时没有这样做。

Answer 3

该错误意味着某些东西没有像关闭括号一样被关闭。您的Classexample3类的结束括号似乎在代码底部缺失。

Answer 4

关闭课程后，如果您缺少}，则会出现很多其他错误。

首先，br.readline()应为br.readLine()

其次，answer.equal("bubble tea")应为answer.equals("bubble tea")

这些事情很重要，如果您使用IDE，它将使您作为Java开发人员的生活变得更加轻松：）
