利用位运算简单实现加密运算

 public static void main(String[] args){
       Scanner scanner = new Scanner(System.in);
       System.out.println("please enter something:");
       String str = scanner.nextLine();
       char[] array = str.toCharArray(); //获取字符数组
        for (int i = 0; i<array.length;i++){
            array[i] = (char)(array[i]^2000);
        }
        System.out.println("加密结果："+ new String(array));
    }
