I have a project to do and I can not convert String to Date . I want to compare the current date with the date of the query that is in the textField Date , and if the current date is past the marked date, it means that the query has already been performed and thus deleting it from the Database . But I can not compare dates. Here is the code commented on the 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
