Date date = new Date();

SimpleDateFormat sdf = new SimpleDateFormat("yyyy年MM月dd日 HH:mm:ss");

System.out.println(sdf.format(date));

SimpleDateFormat sdf2 = new SimpleDateFormat("MM");

System.out.println(sdf2.format(date));

Calendar c = Calendar.getInstance();

System.out.println(c.get(Calendar.MONTH)+1);

Date d=new Date(2010,5,12,13,24,30);

c.setTime(d);

System.out.println(c.get(Calendar.MONTH)+1);

test=new JdbcTest();

  try {
   CallableStatement proc=test.getConnection().prepareCall(sql);
   proc.setString(1, "男");
   //proc.execute();
      ResultSet rs= proc.executeQuery();

    System.out.println(">>>>>>>>>>>>>>>>>>"+sdf.format(time));
    System.out.println(" birthday :"+rs.getDate("birthday"));
      }
