Hello! I put here my solution! I know maybe it's not the best solution but with I'm open to opinions! :)

import java.util.Scanner;

public class Solution {

static boolean isAnagram(String a, String b) {
    boolean check;
    String a1 = a.toLowerCase();
    String b2 = b.toLowerCase();
    char[] sortA1 = a1.toCharArray();
    char[] sortB2 = b2.toCharArray();
    java.util.Arrays.sort(sortA1); 
    java.util.Arrays.sort(sortB2); 
     a1 = new String(sortA1);
     b2 = new String(sortB2);
    if (a1.equals(b2) ) {
        check = true;
    } else {
        check = false;
    }
    return check;
}

public static void main(String[] args) {

    Scanner scan = new Scanner(System.in);
    String a = scan.next();
    String b = scan.next();
    scan.close();
    boolean ret = isAnagram(a, b);
    System.out.println( (ret) ? "Anagrams" : "Not Anagrams" );
}

}
