Java Example - File Renaming

The following example demonstrates the use of the oldName.renameTo(newName) method of the File class to rename a file:

/*
 author by w3cschool.cc
 Main.java
 */import java.io.File;public class Main {
   public static void main(String[] args) {
      File oldName = new File("C:/program.txt");
      File newName = new File("C:/java.txt");
      if(oldName.renameTo(newName)) {
         System.out.println("已重命名");
      } else {
         System.out.println("Error");
      }
   }}

The output result of the above code is (before executing the program, you can Create program.txt file):

已重命名
