Timer:

Time is really easy to keep track off.

Use the code:

System.currentTimeMillis(); gets the current system time in milliseconds. It is such a big number its a long. (remember like double, but holds more places).

So we might say as a global:

long originalTime=System.currentTimeMillis();

And then to find how many milliseconds have passed we could say:

int milliseconds = (int) (System.currentTimeMillis()-originalTime);

Or to find how many seconds have passed we could say:

int seconds = (int) ((System.currentTimeMillis()-originalTime)/1000);

Or to find how many seconds to the tenths place (ie 23.4 seconds) have passed we could say:

double seconds = (int) ((System.currentTimeMillis()-originalTime)/100.0)/10.0;
