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     }
