I have a project to do and I’m not able to convert String for Date. I want to compare the current date with the date of the query that is in textField Date, and if the current date has passed the date marked, that means that the query has already been performed and so delete it from the Database. However I am not able to compare dates. Here is the code commented doubts

 public void PegaData(String dataa) throws ParseException
{
 Date data = new Date(System.currentTimeMillis());
 SimpleDateFormat formatardata = new SimpleDateFormat("dd/MM/yyyy");

 Date dataA =(Date)formatardata.parse(dataa);  //Tentei fazer casting mas nao rolou

 if(dataA.after(data)){
     btConsulta.setEnabled(true);
     System.out.println("data passada");
 }
 else{
       btConsulta.setEnabled(false);
       System.out.println("data no prazo");
      }
 }

returned the exception

(nov 29, 2016 2:56:11 pm projectValueChanged.Agenda listValueChanged GRAVE: null java.text.Parseexception: Unparseable date: " - - ")

Change the section where you call the method PegarData for PegaData(txtData.getText()); or the date mask within this method to dd-MM-yyyy.

The current formatting mask of your date is dd/MM/yyyy, and you are replacing the bar by dash, which bursts the exception, since the date does not arrive with the informed mask formatting.

If it doesn’t work, probably the problem may lie in the value that is coming to be "parsed", judging by the error, it seems that it is only getting to the mask that you applied in the field txtData(why it displays Unparseable date: " - - "), with nothing filled.

  • I did this, but returned the same error, the only difference is that instead of "-" returned "/"

1

It seems that the parameter dataa of the method PegaData(String dataa) is not coming with the value you expect. It seems to me that it is a problem before calling the function, ie the way you are getting the date of Edit.

  • Truth I noticed a mistake here, I’ll take a look and come back with the return

  • Well, I fixed the part and now it is coming with the expected value, returned it the date " 26/11/2016" exactly as it is, but gave another error that follows below: Exception in thread "AWT-Eventqueue-0" java.lang.Classcastexception: java.util.Date cannot be cast to java.sql.Date

  • It seems q is now a mix of types.. vc ta using Date from java.util and Date from java.sql

  • removes the Imports from java.sql.Date and tries to use java.util.Date only
