In this program we will input a name from the user and print its initials.


Example : Input : Mahendra Singh Dhoni

                 Output : M.S. Dhoni


 

Algorithm and Program given below :-


Algorithm :-

  • Input a name in a variable

  • Than add a blank space before the it

  • 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 {     public static void main(String args[])     {         Scanner in = new Scanner(System.in);         String str,str1="",str2="";         char ch,ch1;         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
