JAVA IO - deleteOnExit

若是存在就刪除文件, 不然什麼都不作

Requests that the file or directory denoted by this abstract pathname be deleted when the virtual machine terminates. Files (or directories) are deleted in the reverse order that they are registered. 

import java.io.File;


public class FileDelete {

	/**
	 * @param args
	 */
	public static void main(String[] args) {
		// TODO Auto-generated method stub
		File file = new File("c:\\work\\test");
//		if(!file.exists()){
//			System.out.println("No such file");
//		}else{
//			if(file.delete()){
//				System.out.println("Delete OK");
//			}else{
//				System.out.println("Delete wrong");
//			}
//		}
		
		file.deleteOnExit();
	}
