endDate=aendDate;
public String getEndDate(){
return endDate;
what is the easiest way to carry out a SimpleDateFormat dd/mm/yyyy;
and set a variable to show that there is an error in the date format entered

Answer 1

Then, this may of some help.
import java.text.*;
public class TestFormat{
    public static void main(String[] args){
    SimpleDateFormat form=(SimpleDateFormat)DateFormat.getDateInstance();// ClassCastException be checked
    form.applyPattern("dd/MM/yyyy");//capital letter "MM" be used
    System.out.println(((SimpleDateFormat)form).toPattern());
    ParsePosition position= new ParsePosition(0);
    position.setErrorIndex(-1);//initialize
    Date date=null;
      date=form.parse("4/12-2002", position);//pattern violated
      if(date!=null)  System.out.println(date.toString());
      System.out.println(position.getErrorIndex());
      position.setErrorIndex(-1);//initialize
      date=form.parse("4/12/2002",position);// with pattern
      if(date!=null)  System.out.println(date.toString());
      System.out.println(position.getErrorIndex());  //-1 expected (no error)
}
