如何锁定或提供密码给文件 [英] How to lock or give password to file

问题描述

import java.io.*;

public class CreateFile1{
  public static void main(String[] args) throws IOException{
  File f;
  f=new File("myfile.txt");
  if(!f.exists()){
  f.createNewFile();
  System.out.println("New file \"myfile.txt\" has been created 
  to the current directory");
  }
  }
}

我们可以用密码锁定此文件吗?这样，当任何人在程序中或手动打开此文件时，都应要求输入密码.

Can we lock this file with password. So that when anyone open this file in program or manually it should ask for password.

推荐答案

您不能.当然不是Java.为此，需要外壳程序扩展才能在终端计算机上运行.您最能做的就是将其放在受密码保护的zip中.

You can''t. Certainly not in Java. To do this requires a shell extension to run on the end machine. The closest you can do, is to put it in a password protected zip.
