Anagram check using java

Problem:- Write a Java program to check whether the given two strings are anagrams or not?

Solution:-  So, Let's first understand what is anagrams.

    If a string character is equal to the other string characters where the order is not mandatory then that string is anagrams. 

    for example:- earth and heart,  listen and silent, triangle and integral etc.

    Here earth and heart have the same characters { 'a', 'e', 'h', 'r', 't' }. So earth and heart are anagram strings.

Java code:- 

package com.codeforsolution.java.logical;

import java.util.Arrays;
import java.util.Scanner;

public class AnagramsCheck {

	public static void main(String[] args) {
		Scanner input = new Scanner(System.in);
		System.out.println("Enter 1st String: ");
		String str1 = input.nextLine();
		System.out.println("Enter 2nd String: ");
		String str2 = input.nextLine();
		if (str1.length() == str2.length()) {
			// earth and heart
			char[] charArr1 = str1.toCharArray(); // {'e', 'a', 'r', 't', 'h' }
			char[] charArr2 = str2.toCharArray(); // {'h', 'e', 'a', 'r' ,'t' }

			// now sorting char array
			Arrays.sort(charArr1); // {'a', 'e', 'h', 'r', 't' }
			Arrays.sort(charArr2); // {'a', 'e', 'h', 'r', 't' }

			boolean returnValue = Arrays.equals(charArr1, charArr2);
			if (returnValue) {
				System.out.println("String " + str1 + " and " + str2 + " is  anagram");
			} else {
				System.out.println("String " + str1 + " and " + str2 + " is not anagram");
			}

		} else {
			System.out.println("String " + str1 + " and " + str2 + " is not anagram");
		}
		input.close();

	}

}

Output:- 

Enter 1st String: 

triangle

Enter 2nd String: 

integral

String triangle and integral are anagrams.
