Using SimpleDateFormat class, you can change the format of date.

Here is an example:

import java.util.*;
import java.text.*;
class  DateExample
{
    public static void main(String[] args) 
    {
        Date date=new Date();
        String formats[]={"dd-MM-yyyy","d MMM  yyyy","dd/MM/yyyy","EEE, MMM d,yyyy","dd-MM-yyyy HH:mm:ss"};
        for(int i=0;i<formats.length;i++){
        SimpleDateFormat sdf=new SimpleDateFormat(formats[i]);
        String d=sdf.format(date);
        System.out.println(d);

        }
        }
}
