How to get system date and time?

Question

Can someone show me a code on how to get system date and time.
Thanks!

Answer 1

there is one really easy way to get system time, the api gives a great example of code on this. use gregorian calendar, which you'll find in the api under GregorianCalendar. You only need to create one instance of GC, ie Calendar time = new GregorianCalendar();
you save seconds, minute and hours into int values, so you don't have to access the system time every second, you can create a thread which adds one to the int second value, if oyu see what i mean, for example, i have saved the hours, minutes and seconds as int values;
int hour, minute, second;
i can then create a thread (Thread thread = new Thread(this) and run it like:
Calendar time;
int hour, minute, second;
Thread thread = null;
public MyTime() {
hour= time.get(Calendar.HOUR_OF_DAY);
minute = time.get(Calendar.MINUTE);
second = time.get(Calendar.SECOND);
if(thread == null) {
thread = new Thread(this);
thread.start();
public void run() {
Thread t = Thread.currentThread();
while(thread == t) {
thread.sleep(1000);
second++;
if(second > 59)
minute++;
if(minute>59)
hour++;
formatTime();
public void formatTime() {
second = (second > 59? 0 : second);
minute = (minute > 59? 0 : minute);
hour = (hour > 23? 0 : hour);
System.out.println(hour+":"+minute+":"+second);
public static void main(String[] args) {
new MyTime();
I know this looks like gibberish but it should work. If not, try to fix the problem, i have written from memory really but i guarantee you, this gets the time then every second, simply adds one to the second and then formats time. You can also access the day, month and year then format them using the above code. I don't like giving code since you should really do these things yourself but it is 2:04am, i have nothing better to do and i am not tired so i did you a favour - i have become what i always did not want to, someone ho stays upall night writing code.
