Example:
package com.w3spoint;
import java.io.File;
public class RenameFileTest {
public static void main(String args[]){
try {
//File to rename
File oldFile = new File("D:/Test files/file 3.txt");
//File for rename
File neaFile = new File("D:/Test files/newTest.txt");
//Rename the specified file
if(oldFile.renameTo(neaFile)){
System.out.println("File renamed successfully");
}else{
System.out.println("File not renamed successfully");
}
} catch (Exception e) {
e.printStackTrace();
}
}
