Anagram Problem

public class AnagramSolver {
    public static boolean areAnagrams(String str1, String str2) {
        String sortedStr1 = sortString(str1);
        String sortedStr2 = sortString(str2);
        return sortedStr1.equals(sortedStr2);
    }

    private static String sortString(String str) {
        return Arrays.stream(str.split(""))
                .sorted()
                .collect(Collectors.joining());
    }

    public static void main(String[] args) {
        System.out.println(areAnagrams("listen", "silent"));  // Outputs: true
        System.out.println(areAnagrams("hello", "world"));  // Outputs: false
    }
}

In this code, we first sort the characters in each string using a stream. Then we compare the sorted strings. If they are equal, then the original strings are anagrams.
