import java.util.Arrays;

public class AnagramChecker {
    public static void main(String[] args) {
        String str1 = "listen";
        String str2 = "silent";
        boolean areAnagrams = checkAnagram(str1, str2);
        System.out.println(str1 + " and " + str2 + " are " + (areAnagrams ? "anagrams" : "not anagrams"));
    }

    private static boolean checkAnagram(String str1, String str2) {
        char[] charArray1 = str1.toCharArray();
        char[] charArray2 = str2.toCharArray();
        Arrays.sort(charArray1);
        Arrays.sort(charArray2);
        return Arrays.equals(charArray1, charArray2);
    }
