代码

public static boolean isAnagram(String s,String t){
        char[] x = s.toCharArray();
        char[] y = t.toCharArray();
        Arrays.sort(x);
        Arrays.sort(y);
        boolean val = Arrays.equals(x, y);
        return val;
    }

测试如下

public static void main(String[] args) {
        String s = "anagram";
        String t = "nagaras";
        boolean val = isAnagram(s, t);
        System.out.println(val);
    }

结果
