我有个约会 String newDate = "31.05.2001"

我必须增加1天.

我尝试了以下代码:

String dateToIncr = "31.12.2001";
String dt="";
SimpleDateFormat sdf = new SimpleDateFormat("dd.mm.yyyy"); 
Calendar c = Calendar.getInstance();
try {
    c.setTime(sdf.parse(dateToIncr));
} catch (ParseException e) {
    // TODO Auto-generated catch block
    e.printStackTrace();
} 
c.add(Calendar.DAY_OF_MONTH, 1);  // number of days to add
dt = sdf.format(c.getTime());
System.out.println("final date now : " + dt);

但是使用这个代码,它只是设法添加DAY,即31.05.2001的输出将是1.05.2001,保持月份和年份不变!请帮我解决一下这个.

我也试过了

c.roll(Calendar.DATE, 1);  // number of days to add

我是Scala和Play框架的新手.我必须创建一个"CONTACTS"模块,但是我收到以下错误:

type mismatch found : Unit required: play.api.mvc.Result 
    contactVal.save()
where contactVal is defined as 
    val contactVal  = new Contact(service) where service is 
    val service = new ExchangeService()

如何保存新的EWS联系人？

我的代码:

def add = Action(parse.json) {
  implicit r=>
    val contactVal  = new Contact(service)
    val userId = (r.body \ "userId").asOpt[String].getOrElse("")
    val contactId = (r.body \ "id").asOpt[String].getOrElse("")
    val givenName = (r.body \ "givenName").asOpt[String].getOrElse("")
    val fName = (r.body \ "fName").asOpt[String].getOrElse("")
    val lName = (r.body \ "lName").asOpt[String].getOrElse("")
    val displayName = (r.body \ "displayName").asOpt[String].getOrElse("")
    val emailId1 = …
