Dispay non-String variable to JLabel

I wonder if JLabel really can't display a value beside String and Icon. For example for displaying Clock variable..

Clock clock = Clock.systemDefaultZone();

And the JLabel setText() method as following..

label.setText(clock);

I'm aware that setText() method only works with String parameter. But since clock variable can't be converted to String, i really have no idea how to display it on the label. Or what should i use instead of JLabel to display Clock variables.

I tried label.setText(Clock.valueOf(clock));, until later i realized that only works for primitive data (or no?). I really stuck at this moment.

I'm going to assume you're using java.time.Clock. You can convert the current time into an ISO-8601 string by doing clock.instant().toString().

Therefore, you can put the clock in the label using:

label.setText(clock.instant().toString());

If you want the label to show the clock updating, you may need to use something like a Timer to reset the label text every second.

You can change the formatting if you don't want ISO-8601 with this to set your own format.

JLabel will set the text to an object if you have overridden the toString() method and call to it..

As 

System.out.println(clock); //this would automatically call the toString() method.

For this.. You would have to directly call it.

label.setText(clock.toString());
