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");
    		}
    	}
    }
