how system.timeinms works java code example

Example: system.currenttimemillis()

// gets total number of milliseconds since the UNIX Epoch
long totalMilliseconds = System.currentTimeMillis();

long totalSeconds = totalMilliseconds / 1000;
long currentSeconds = totalSeconds % 60;

long totalMinutes = totalSeconds / 60;
long currentMinutes = totalMinutes % 60;

long totalHours = totalMinutes / 60;
long currentHours = totalHours % 24;

// first function call MUST be long
// current times don't have to be long, can be {int, double, etc...}
// total times should usually be long
