DateFormat question

[adam Lui]

 1. import java.text.*;
2. class DateOne {
3. public static void main(String[] args) {
4. Date d = new Date(1123631685981L);
5. DateFormat df = new DateFormat();
6. System.out.println(df.format(d));
7. }
8. }   

in order to successfully print that Date, I am trying to fix this code. (question copied from K&B book, chapter 6, p511)

can you help me to fix? this topic is still really confusing me!

Class DateFormat is an abstract class. You cannot instantiate an abstract class, as you are doing in line 5 of your code. Replace line 5 with something like this:

DateFormat df = new SimpleDateFormat("MM/dd/yyyy");

And you also need to import java.util.Date.
