    Using Java API to improve readibility.

    import java.util.*;
    public class Solution {
        public boolean isAnagram(String s, String t) {
            /*
            * first sort the string, and then compare if they equals each other.
            * 先对字符串进行排序,然后比较是否相等
            */
            if(s.length() == 0 ) {
                if (t.length() == 0) return true;
                else return false;
            }
            char[] sArr = s.toCharArray();
            char[] tArr = t.toCharArray();
            Arrays.sort(sArr);
            Arrays.sort(tArr);
            return Arrays.equals(tArr, sArr);
            
        }
    }
