How to rename a file in java

In this post, we will see how to rename a file in java. We can use java.io.File ‘s rename(File dest) method to rename a file. rename method returns true if operation is success else returns false. It can use this method to move a file also.

You should always check if rename operation is successful or not because it does not throw any exception

Java Program:

package org.arpit.java2blog;

import java.io.File;

public class RenameFileMain {
 /*
  * @Author : Aprit Mandliya
  */

 public static void main(String[] args) {

  System.out.println("-----------------");

  // Read the file
  File configFile=new File("/Users/Arpit/Desktop/config.properties");
  // destination file object
  File configFileNew=new File("/Users/Arpit/Desktop/config_new.properties");
  boolean remameSuccess=configFile.renameTo(configFileNew);

  if(remameSuccess)
  {
   System.out.println("Rename operation is successful");
  }
  else
  {
   System.out.println("Rename operation is unsuccessful");
  }

  System.out.println("-----------------");
 }

}

When I ran above program, I got following output:

-----------------
Rename operation is successful
-----------------
