How to rename file in Java

Java comes with renameTo() method to rename a file. However , this method is really platform-dependent: you may successfully rename a file in *nix but failed in Windows. So, the return value (true if the file rename successful, false if failed) should always be checked to make sure the file is rename successful.

File.renameTo() Example

package com.mkyong.file;
 
import java.io.File;
 
public class RenameFileExample 
{
    public static void main(String[] args)
    {	
 
		File oldfile =new File("oldfile.txt");
		File newfile =new File("newfile.txt");
 
		if(oldfile.renameTo(newfile)){
			System.out.println("Rename succesful");
		}else{
			System.out.println("Rename failed");
		}
 
    }
}
