        for (int i = 0; i < str.length(); i++) {
            char ch = str.charAt(i);
            char temp = (char)(ch^key);
            str_ += String.valueOf(temp);
            System.out.print(temp);
        }
        System.out.println();
        //解密
        for (int i = 0; i < str_.length(); i++) {
            char ch = str_.charAt(i);
            char temp = (char)(ch^key);
            System.out.print(temp);
        }
