“/”和“\”

1 微软支持两种路径“/”和“\”但是linux只支持"/"
2 如果使用\的时候要使用两个\\第一个用来给第二个转义
package com.xiewanzhi.property;

import java.io.BufferedReader;
import java.io.FileReader;
import java.io.IOException;

public class leb {

    public static void main(String args[]) throws IOException
    {
        BufferedReader input = new BufferedReader(new FileReader("G:\\2.txt"));
        String line = null;
        while((line = input.readLine())!=null)
        {
          System.out.println(line);
        }
        
        input = new BufferedReader(new FileReader("G:/2.txt"));
        line = null;
        while((line = input.readLine())!=null)
        {
          System.out.println(line);
        }
