     public static void main(String[] args) {

         int i = 1;

         System.out.println("i 右移两位：" + (i>>2) ); //

         System.out.println("i 左移两位：" + (i<<2) ); //

         for (int j = 0; j < 4; ++j) {

             int  result  = 1 << ((j + 2) % 4);

             //  "<<"为左结合性

             System.out.println("1 << ((" + j + " + 2) % 4)) = " + result);
