How to get current date time?

You can get current date and/or time in Java using the following method. You may change the date format in the constructor of SimpleDateFormat to get the result in a different format:
import java.util.Date;
import java.text.DateFormat;
import java.text.SimpleDateFormat;

private String getDateTime() {
DateFormat dateFormat = new SimpleDateFormat("yyyy/MM/dd HH:mm:ss");
Date date = new Date();
return dateFormat.format(date);
}
