我在文本文件中显示我的游戏分数时遇到问题，我有两个文本文件，一个用于播放器详细信息，但是在我输入分数后，其他文本文件没有出现在得分文本文件中修改的日期与我完成游戏的时间相同，只是分数没有出现。这是我的代码：
import java.util.Scanner;
import java.io.*;
public class Project
{
public static void main (String[]args) throws FileNotFoundException // This shows that the programme might encounter a file which is not there.
{
String outputFileName ="players.txt";
//Storing the name of the text file
PrintWriter writeToFile = new PrintWriter(outputFileName);
//This allows me to write to the text file that I've called outputFileName
Scanner playerStringInput = new Scanner(System.in);
Scanner playerIntInput = new Scanner(System.in);
//Taking info from the keyboard, one is for Integers and the other is for String
String name = " ";
String nickName = " ";
String homeTown = " ";
int age = 0;
int previousGamesPlayed = 0;
//Declaring the variables that I'm going to use to store the inputs from the programme
int amtOfPlayers = 2; //The amount of players we have
for(int i = 0; i < amtOfPlayers; i++) //Loop for both players
{
System.out.println("1.Please Enter Name");//Prints out instructitions for user.

答案 0 :(得分：2)
您的上一句话应该是writeToFile.close()，而不是from unittest.mock import patch
from contextlib import contextmanager
@contextmanager
def use_mocked(method, cls, ret_value):
class MockedClass(cls):
pass
def func(cls):
return ret_value
def fullname(o):
return o.__module__ + "." + o.__name__
setattr(MockedClass, method, classmethod(func))
with patch(fullname(cls), MockedClass):
yield
。你正在关闭第一个文件两次。在程序结束之前，缓冲区没有被刷新到文件中。
