通过java可以修改文件为只读权限

package com.zuidaima.util.file;import java.io.File;import java.io.IOException;/** * 修改文件为只读权限 *  * @author javaniu *  */public class MakeFileReadOnly { public static void main(String[] args) throws IOException {  File file = new File("c:/file.txt");  // mark this file as read only, since jdk 1.2  file.setReadOnly();  if (file.canWrite()) {   System.out.println("This file is writable");  } else {   System.out.println("This file is read only");  }  // revert the operation, mark this file as writable, since jdk 1.6  file.setWritable(true);  if (file.canWrite()) {   System.out.println("This file is writable");  } else {   System.out.println("This file is read only");  } }}
