Question

I need System.currentTimeMillis() to be converted into 3 variables:

int Years;
int DaysMonths;
int MinutesHours;

What I mean by DayMonths, and MinutesHours is that, let’s say for example we have 2 hours. Then MinutesHours should equale 120 (because 2hours = 120 minutes). But once it reaches 24hours, it should be 0 and passe it to DaysMonths.
Same thing for the DaysMonths variable.

And I also need to know how to get this thing reversed. Using this 3 variables, I need an other method to get the System.currentTimeMillis() from them.

I’m having hard time to explain this, but I hope you know what I mean. I really hate dealing with time in java. It’s not my thing, but I need it really bad for a game project.

Answer 1

Create a Calendar object:

long millis=System.currentTimeMillis();
Calendar c=Calendar.getInstance();
c.setTimeInMillis(millis);

After this you can get the fields from the Calendar object:

int hours=c.get(Calendar.HOUR);
int minutes=c.get(Calendar.MINUTE);

Then:

int MinutesHours=(hours*60)+minutes;

To go back, you can use the set method in Calendar:

Calendar c=Calendar.getInstance();
c.set(Calendar.MINUTE,minutes);
long millis=c.getTimeInMillis();
