1. String date = "2016-01-10"

public class TestDateExample2\ {

    public static void main(String[] argv) {

        SimpleDateFormat formatter = new SimpleDateFormat("yyyy-MM-dd");
        String dateInString = "2016-01-10";

        try {

            Date date = formatter.parse(dateInString);
            System.out.println(date);
            System.out.println(formatter.format(date));

        } catch (ParseException e) {
            e.printStackTrace();
        }

    }

}

2. String date = "8-Jun-2016"

public class TestDateExample {

    public static void main(String[] argv) {

        SimpleDateFormat formatter = new SimpleDateFormat("dd-MMM-yyyy");
        String dateInString = "8-Jun-2016";

        try {

            Date date = formatter.parse(dateInString);
            System.out.println(date);
            System.out.println(formatter.format(date));

        } catch (ParseException e) {
            e.printStackTrace();
        }

    }

}

3. String date = "Fri, Jun 8 2016"

public class TestDateExample {

    public static void main(String[] argv) {

        SimpleDateFormat formatter = new SimpleDateFormat("E, MMM dd yyyy");
        String dateInString = "Fri, Jun 8 2016";

        try {

            Date date = formatter.parse(dateInString);
            System.out.println(date);
            System.out.println(formatter.format(date));

        } catch (ParseException e) {
            e.printStackTrace();
        }

    }

}

4. String date = "Monday, Jun 8, 2016 10:30:00 AM"

public class TestDateExample {

    public static void main(String[] argv) {

        SimpleDateFormat formatter = new SimpleDateFormat("EEEE, MMM dd, yyyy HH:mm:ss a");
        String dateInString = "Monday, Jun 8, 2016 10:30:00 AM";

        try {

            Date date = formatter.parse(dateInString);
            System.out.println(date);
            System.out.println(formatter.format(date));

        } catch (ParseException e) {
            e.printStackTrace();
        }

    }

}

Good luck!
