2、java如何删除文件

package com.tij.io.file;

import java.io.File;

public class DeleteFileJava {

	/**
	 * This is Shows How to delete a File in Java
	 * @param args
	 */
	public static void main(String[] args) {
		//absolute file name with path
		File file = new File("/Users/GYJ/file.txt");
		if (file.delete()) {
			System.out.println("/Users/GYJ/file.txt" + "File deleted");
		} else {
			System.out.println("File /Users/GYJ/file.txt doesn't exists");
		}
		
		//file name only
		file = new File("file.txt");
		if (file.delete()) {
			System.out.println("file.txt File deleted from Project root directories");
		} else {
			System.out.println("File file.txt doesn't exists in Project root directories");
		}
		
		//relative path
        file = new File("temp/file.txt");
        if (file.delete()) {
            System.out.println("tmp/file.txt File deleted from Project root directory");
        } else {
        	System.out.println("File tmp/file.txt doesn't exists in project root directory");
        }
		
        //delete empty directory
        file = new File("temp");
        if (file.delete()) {
        	System.out.println("temp directory deleted from Project root directory");
        } else {
        	System.out.println("temp dierctory doesn't or not empty in Project root directory");
        }
        
        //try to delete directory with files
        file = new File("/Users/GYJ/project");
        if (file.delete()) {
            System.out.println("/Users/GYJ/project directory deleted from Project root directory");
        } else {
        	System.out.println("/Users/GYJ/project directory doesn't exists or not empty");
        }
	}
}
out put=================
File /Users/GYJ/file.txt doesn't exists
File file.txt doesn't exists in Project root directories
tmp/file.txt File deleted from Project root directory
temp directory deleted from Project root directory
/Users/GYJ/project directory doesn't exists or not empty
