Java anagram工作代码，帮助理解代码的概念

import java.util.Arrays;

public class AnagramChecker {
    public static boolean isAnagram(String str1, String str2) {
        // 将字符串转换为字符数组，并对字符数组进行排序
        char[] charArray1 = str1.toCharArray();
        char[] charArray2 = str2.toCharArray();
        Arrays.sort(charArray1);
        Arrays.sort(charArray2);

        // 比较排序后的字符数组是否相等
        return Arrays.equals(charArray1, charArray2);
    }

    public static void main(String[] args) {
        String str1 = "listen";
        String str2 = "silent";

        if (isAnagram(str1, str2)) {
            System.out.println(str1 + " and " + str2 + " are anagrams.");
        } else {
            System.out.println(str1 + " and " + str2 + " are not anagrams.");
        }
    }
}
