A question of calculation

[chrisjwebb1978]

Hi all

I am new to Java which is why i am posting here...

I have a thread that throws 5000 at the code below...

double slpAmnt = (double)Math.random()*5000; // work out sleep amount
try	{
	sleep((long)slpAmnt);// sleep for sleep amount
} 
catch (Exception e1) {
	e1.printStackTrace();
}

I would very much appreciate advice on what the emboldened code does with 5000?

I think i understand the Math.random()*5000 produces anything in the range of 0 to 5000, but am unsure what the rest does?

Many thanks for any replies

Try reading the API doc for the sleep() method to see what it does.
