我需要有关Java中双反斜杠和单反斜杠的帮助

问题描述

大家好，

我知道"\"是转义字符，但是真的不可能将它读作正常"字符吗?

我想逐个字符地读取路径(以字符串形式读出)，并检查一个路径是否为反斜线..但这仅在我在路径中加上双反斜线时才有效.

希望您能对我有所帮助！

Hi guys,

I know that "\" is an escape character, but is there really no possibility to read it as a "normal" character?

I wanted to read a path (which is read out in a string) character by character and check whether one is a backslash.. but that only works if i put double backslashes in the path.

Hope you can help me!

推荐答案

String slash = "\\";

别无选择.

There''s no alternatives.

import java.util.Properties;
import java.io.File;
import java.io.FileInputStream;
import java.io.FileNotFoundException;
import java io.IOException;

并用
加载文件

and loaded the file with

private static String InFile;
String Path;

Properties props = new Properties();
FileInputStream in = null;

// create input stream to read file
try{
    in = new FileInputStream(new File(Path));
} catch(FileNotFoundException e1) {
    ErrorHandling.printError("Error");
}

try{
    props.load(in);
} catch(IOException e) {
    ErrorHandling.printError("Error");
}

我通过用关键词p.E.在文件中搜索来找到自己的路径.

I got my path by searching in file by a key word p.E.

InFile = props.getProperty("Path=");

那不是我所做的好主意.
如我所说，我想检查路径中是否有反斜杠，如果是，则添加另一个反斜杠.
好吧，这就是我所做的，而不是使用此属性:

and thats not a good idea for that what I did.
As I said, I wanted to check if there is any backslash in the path, if yes then add another backslash.
Well, that''s what I did instead of using this properies:

import java.util.Scanner;
import java.io.FileReader;

String Lines = null;

FileReader fr = new FileReader(Path);
Scanner input = new Scanner(fr);

// read out each line of file
while(input.hasNextLine())
{
    Lines = input.nextLine();
    System.out.println(Lines);
}

我希望每个人都能理解我要解释的内容:)
