Raw java code:

import java.util.Scanner;
//creating a class called Name_Reverse
public class Name_Reverse {
   //main method
   public static void main(String[] args) {
       //dialogue to the user
       System.out.print("Please enter your full name: ");
       //Creating an object using Scanner class
       Scanner inp=new Scanner(System.in);
       //taking the String using .nextline method from the object created previously
       String name= inp.nextLine();
       //splitting the string based on spaces entered in between the name, and creating the array
       String[] rev=name.split(" ");
       //output dialogue to the user
       System.out.print("Your name in reverse order is ");
       //looping through the array to print the reverse order of names
       for(int i=rev.length-1;i>=0;i--) {
           // condition to not to print the , at the end as per your requirement show in your output
           if(i==0) {
               System.out.print(rev[i]);
           }
           //condition to print the reverse of the name by inserting , after every string
           else {
               System.out.print(rev[i]+",");
           }
       }
