Java program to rename an existing file

Consider the program:

import java.io.File;
import java.io.IOException;

public class RenameFile {
  public static void main(String[] args) {
    try
    // Here F is the object of the Existing file named 
    // with Includehelp which is to be renamed
    {
      File F = new File("f:/Includehelp.txt");

      // Here T is the object of the renamed file 
      // of Includehelp which is Include.txt
      File T = new File("f:/Include.txt");

      // Rename the file Includehelp.txt 
      // into Include.txt
      F.renameTo(T);

      // Print the result if file renamed
      System.out.println("File Rename Successfully...");
    }
    // If any error occurs while renaming the file
    catch (Exception e) {
      System.out.println(e);
    }
  }
}

Output

File Rename Successfully...
