Answer 1

try this::

    public static void main(String[] args) throws ParseException { 
    String invoice="20200302-ababab";
    String[] split =invoice.split("-");
     SimpleDateFormat formatter = new SimpleDateFormat("yyyyMMdd");
     Date date =  formatter.parse(split[0]);

     System.out.println(date.toString());

}

output::

Mon Mar 02 00:00:00 IST 2020

Answer 2

If your date looks like "20200302" the formatter should look like:

SimpleDateFormat formatter = new SimpleDateFormat("yyyyMMdd");
