Program to check whether string is anagram or not?

Favorite question of  interviewer.

package com.iacsd.java;

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

public class anagram
{

public static void main(String[] args)
{

  Scanner sc =new Scanner(System.in);

    String s1=sc.nextLine(); // enter the first string

    String s2=sc.nextLine(); // enter the second string
 
    if(s1.length() == s2.length()) // compare the length of both string
    {
    char arr1[]=s1.toCharArray(); // convert the string into a character type array

    char arr2[]=s2.toCharArray(); // convert the string into a character type array
 
    Arrays.sort(arr1);  // By calling sort method, we sort the array

    Arrays.sort(arr2);

    boolean check=true; // variable for checking
 
    for(int i=0; i<arr1.length; i++)
    {
    if(arr1[i]!=arr2[i]) // compare the character of both character type array
    {
    check=false;
    }
    }
    if(check==true)
    {
    System.out.println("Both strings are anagram");
    }
    else
    {
    System.out.println("not anagram");
    }
}

}
}


example-
i/p 1 is army

i/p 2 is mary

o/p strings are anagram.

i/p 1 abc

i/p 2 zxc

o/p strings are not anagram.
