• Find the length of the name in a variable
• now find the last blank space index in a new variable
• Store the part of the string from last blank space in a new variable
• Start a for loop till last index of blank space
• Extract the characters from the string.
• if blank space is found than add the next character after the space and add (.)
• Add both this and string with last part of the string
• Print the Result.

Program :-

import java.io.*;
import java.util.*;
class Initial_Name

        Scanner in = new Scanner(System.in);
        String str,str1="",str2="";

        int l,p,i;
        System.out.print("Enter Word : ");
        str=in.nextLine();
        str=" "+str;
        l= str.length();
        p= str.lastIndexOf(" "); // find the index of last blank space
        str2= str.substring(p+1); // Storing the Last part of the string
        for(i=0;i<p;i++)
        {
            ch=str.charAt(i);
            if(ch==' ')
            {
                str1=str1+str.charAt(i+1)+"."; // Storing Initials
            }
        }
        str2=str1+str2; // Adding initials and Surname
        System.out.println("Original Name : "+str);
        System.out.println("Initial Name : "+str2);
    } // end of main
} // end of class

All the best :)
