//You can use this for both date or time.
// long timestamp = System.currentTimeMillis();
// eg: for date use it like this:
//timestampToDate(timestamp, "dd MMM, yyyy");

//timestampToDate(timestamp, "hh:mm a");
// eg: for both:
//timestampToDate(timestamp, "dd MMM, yyyy - hh:mm a");

date to timestamp java

All you need to do is change the string within the java.text.SimpleDateFormat constructor to: "MM-dd-yyyy HH:mm:ss".

Just use the appropriate letters to build the above string to match your input date.
