Java代码如何修改文件名呢?

修改文件名的实现思路
    使用file.renameTo方法
	即可实现修改文件名的效果

package com.java265;
 
import java.io.File;

public class TestClass {
 
	private static String path = "D:/Test";
	private static String oldName = "test.txt";
	private static String newName = "new.txt";
 
	public static void main(String[] args) {
		File file = new File(path);
		renameFile(file);
		System.out.println("finished.");
	}
	
	private static void renameFile(File file) {
		if(file != null) {
			if(file.isDirectory()) {
				File[] chfs = file.listFiles();
				for (File chf : chfs) {
					renameFile(chf);
				}
			}else {
				if(oldName.equals(file.getName())) {
					System.out.println("start rename:" + file.getAbsolutePath());
					file.renameTo(new File(file.getParent() + "/" + newName));
				}
			}
		}
	}	
}
