Always remember that whenever a string question is thrown at you, just remember this "A string is noting but an array of character that ranges from 0-256 chars(assuming all the char are alphabets)"

Now to the question,
you can sort the first and sort the second using library function,
and compare each char by char
Time Complexity -> O(n*logn)
## If len(str2) != len(s1) -> return false, strings of uneven lengths can never be anagrams

import java.util.*;
class Anagrams {

  static boolean isAnagram(String a, String b) {
        char c[] = a.toLowerCase().toCharArray();
        char d[] = b.toLowerCase().toCharArray();
        Arrays.sort(c);
        Arrays.sort(d);
        if(Arrays.equals(c,d)){
            return true;
        }
        return false;
    }



  public static void main(String[] args) {
     Scanner scan = new Scanner(System.in);
    System.out.println("Enter first String: ");
    String a = scan.next();
    System.out.println("Enter seconf jumbled String");
    String b = scan.next();
    scan.close();
    boolean ret = isAnagram(a, b);
    System.out.println( (ret) ? "Anagrams" : "Not Anagrams" );
    }
}
