如何检查一年中的月份是否为1月,它将查看数据库表,如果有12月(12)和年/去年,它将插入到该表中,如果没有

示例在这里,但它不起作用

  SimpleDateFormat king = new SimpleDateFormat("MM");
  String M = (king.format(new java.util.Date()));
  String L = M;
  if (L.equals(1)) {
     // then it will check the database table if there is none
     // if the rs.next is false then it will count and insert the last 
     // month and last year patient

  } else() { 
    // if it is not Month of January then it will insert the last month this work 
    // for me but the other is not

  } …
