用于Mac的Java文件输入 [英] File input in Java for Mac

问题描述

我们正在学习编程类中的文件输入和输出，但是我有一台Macbook Pro。我知道如何做到这一点，我可以在Windows上做到这一点，但我很难找到如何正确地为Mac做到这一点。我似乎无法弄清楚在File Fred = new File（）中引用什么内容。我需要在报价中加入什么才能起作用？我在名为David的HDD中有文件。

  import java.util.Scanner; 
 import java.io. *; 
 
 public class FileIO 
 {
 
 public static void main（String [] args）
 {
 
 File Fred =新文件（David：\\mytext.txt）; 
 try 
 
 
 $ div class =h2_lin>解决方案Mac OS中，使用/（正斜杠）而不是\（反斜杠）来分隔路径中的文件。硬盘位于/卷下。所以你的文件可能是/Volumes/David/mytext.txt。
 
We're learning file input and output in my programming class right now, but I have a Macbook Pro. I understand how to do it and I can do it on Windows but I'm having trouble finding out how to do it exactly for a Mac. I just can't seem to figure out what to put in the quotes for the 'File Fred = new File(" "); What do I need to put in the quotes to have it work? I have the file in the HDD named "David". 
import java.util.Scanner;
import java.io.*;

public class FileIO
{

public static void main(String[] args)
{

    File Fred = new File("David:\\mytext.txt");
    try
    {   

解决方案
On Mac OS, you use "/" (forward slash) and not "\" (backward slash) to separate files in a path. Hard drives are located under "/Volumes". So your file is probably /Volumes/David/mytext.txt .
