利用位运算简单实现加密运算

 1  public static void main(String[] args){ 2        Scanner scanner = new Scanner(System.in); 3        System.out.println("please enter something:"); 4        String str = scanner.nextLine(); 5        char[] array = str.toCharArray(); //获取字符数组 6         for (int i = 0; i<array.length;i++){ 7             array[i] = (char)(array[i]^2000); 8         } 9         System.out.println("加密结果："+ new String(array));10     }

只要有信心，人永远不会挫败
