Java Strings Introduction | HackerRank Solution

Hello coders, today we are going to solve Java Strings Introduction HackerRank Solution.

"A string is traditionally a sequence of characters, either as a literal constant or as some kind of variable." — Wikipedia: String (computer science)
Java Strings Introduction


This exercise is to test your understanding of Java Strings. A sample String declaration:

 String myString = "Hello World!"

The elements of a String are called characters. The number of characters in a String is called the length, and it can be retrieved with the String.length() method.

Given two strings of lowercase English letters, A and B, perform the following operation:

  1. Sum of length of A and B.
  2. Determine if A is lexicographically larger than B(i.e.: B comes after A in dictionary?).
  3. Capitalize the first letter of A and B and print them on a single line, separated by a space.

Input Format

The first line contains a string A. The second line contains another string B. The strings are comprised of only lowercase English letters.

Output Format

There are three lines of output:
For the first line, sum the lengths of A and B.
For the second line, write Yes if is A lexicographically greater than B otherwise print No instead.
For the third line, capitalize the first letter in both A and B and print them on a single line, separated by a space.

Sample Input
Sample Input
 Hello Java

String A is “hello” and B is “java”. A has a length of 5, and B has a length of 4; the sum of their lengths is 9.
When sorted alphabetically/lexicographically, “hello” precedes “java”; therefore, A is not greater than B and the answer is No. When you capitalize the first letter of both A and B and then print them separated by a space, you get “Hello Java”.

Solution – Java Strings Introduction

import java.util.*;

public class Solution {

    public static void main(String[] args) {
        Scanner sc=new Scanner(;
        /* Enter your code here. Print output to STDOUT. */
         int len_A = A.length();
         int len_B = B.length();
         else  System.out.println("No");
         System.out.print(((A.substring(0,1)).toUpperCase().concat(A.substring(1,len_A)))+" "+
