3、了解java的文件4种分隔符

java.io.File类中有四种静态分隔符; 分别是separator separatorChar pathSeparator pathSeparatorChar

separator : 它属于平台默认的字符形式， 列如window "\" unix "/"
separatorChar  : 同上，但是表示字符
pathSeparator  ： 表示为各个平台classPath 分割的变量，window： ";" unix ":"
pathSeparatorChar : 同上，但是表示字符

测试============

package com.tij.io.file;

import java.io.File;

/**

public class FileSeparator {

	/**
	 * 	ava.io.File class contains four static separator variables. Here we will learn about them and when to use it.
		s	eparator: Platform dependent default name-separator character as String. For windows, it’s ‘\’ and for unix it’s ‘/’.
		separatorChar: Same as separator but it’s char.
		pathSeparator: Platform dependent variable for path-separator. For example PATH or CLASSPATH variable list of paths separated by ‘:’ in Unix systems and ‘;’ in Windows system.
		pathSeparatorChar: Same as pathSeparator but it’s char.
	 * @param args
	 */
	public static void main(String[] args) {
		System.out.println("File.separator = "+File.separator);
        System.out.println("File.separatorChar = "+File.separatorChar);
        System.out.println("File.pathSeparator = "+File.pathSeparator);
        System.out.println("File.pathSeparatorChar = "+File.pathSeparatorChar);
	}

}

out put =============
window：
File.separator = \
File.separatorChar = \
File.pathSeparator = ;
File.pathSeparatorChar = ;

unix：
File.separator = /
File.separatorChar = /
File.pathSeparator = :
File.pathSeparatorChar = :
