In this blog post ,I will be showing you how you can rename a file. Consider the following code snippet:

package learnjava.io;

import java.io.File;

public class RenameFileDemo { 
    public static void main(String args[]){ 
        String fileName = "C:/Test.txt"; 
        String newFileName = "C:/test2.txt"; 
        File file = new File(fileName); 
        if(file.exists()){ 
            File newFile = new File(newFileName); 
            boolean renamed = file.renameTo(newFile); 
            if(renamed) 
                System.out.println("File renamed successfully"); 
            else 
                System.out.println("There was an error in renaming the file"); 
        } else 
            System.out.println("File is missing"); 
    } 
}

If you run this code, it will produce the following output:

File renamed successfully

There is a method called File.renameTo which can be used to rename a file. It accepts as argument a file object. The file object should be constructed with the new name to be given to the file. Note that the full path needs to be specified.
