Java代码如何锁定文件呢？

实现思路:
    借助FileChannel.lock即可锁定文件

package com.java265.other;
import java.io.File;
import java.io.FileInputStream;
import java.io.InputStreamReader;
import java.io.Reader;
public class test {
	/*
	 * java265.com 锁定文件的示例分享
	 */
	public static void main(String[] args) throws Exception {

		File file = new File("D:\\test.txt");
		FileInputStream in = new FileInputStream(file);
		    java.nio.channels.FileLock lock = in.getChannel().lock();
		try {
			Reader reader = new InputStreamReader(in, "UTF-8");
		} catch (Exception e) {
			e.printStackTrace();
		}
	}
}
