Date curent_date = new Date();
if you do : System.out.println("Created date : " + curent_date.toString()); will be printed out the curent date
that's all. If you want more than that (i.e. working with the year, month, etc ...) You must use an instance of java.util.Calendar or java.util.GregorianCalendar. Please fill free to ask.

public class DateGenerator {
  public static void main(String[] args) {
    System.out.println("Curent date is : " + (new Date()).toString());
  }
}

Compile this and run'it.

System.currentTimeMillis() produces the current time in milliseconds with a resolution dependent upon your the native system's clock.

java.util.Date wraps the millisecond value and provides some comparison behavior although most of its useful behavior has been deprecated and moved to java.util.Calendar and its concrete subclasses. The no-arg constructor of Date initializes the new Date object with the current time provided by System.currentTimeMillis().

java.util.Calendar provides facilities for getting and setting specific date parts (like seconds, months, years) and for performing date arithmetic.

java.text.DateFormat and its more useful class java.text.SimpleDateFormat perform Date formatting to Strings and parsing from Strings.

Taken together, one or more of these classes is likely to have the functionality you are looking for with respect to "generating the current time".

Best regards,

DateFormat dateFormat = DateFormat.getDateInstance();
Calendar calender = dateFormat.getCalendar();
System.out.println("time"+calender.getTime());
