Date and Time
This page will teach you about using the Date import in Java to output or get the current Time and/or Date.
When is this needed?
Adding a simple clock or date counter to an application adds a slightly more professional look to the overall appeal of the program, as well as having the time handy is always a good thing.
What imports are needed?
The imports we need to get the current Date and Time are;
- import java.util.Date;
- import java.text.SimpleDateFormat;
these allows us to get the Date and Time, and then format them the way we want to.
Here is an example of sending the String "Current Date: " followed by the date in Day DayDay.Month.Month.Year.Year.Year.Year format, followed by a similar technique for the date:
- System.out.println("Current Date: " + ft.format(dNow));
As you can probably tell, each character in the SimpleDateFormat stands for something different...
E - Day in full letters
d - Day in numeric values
M - Month in numeric values
y - Year in numeric values
h - Hours in numeric values
m - Minutes in numeric values
s - Seconds in numeric values
a - "AM"/"PM"
z - Timezone.
The output given from the example is:
Current Date: Sun 01.12.2013. Current Time: 09:29:31 PM GMT
