		int year,month,day;
	}

	class e{
		void  test(MyDate d,MyDate d2,int s){
			d.day = s;
			s = 30;
			d2 = new MyDate();
			d2.day = 100;
		}

		public static void main(String args[]){
			int s = 10;
			MyDate d = new MyDate();
			MyDate d2= new MyDate();
			d.day = 1;
			d2.day = 2;
			e t = new e();
			t.test(d,d2,s);
			System.out.println(d.day);
			System.out.println(d2.day);
			System.out.println(s);
		}
