Java Programming - Math.class

Mr. Skidoodles

I'm just starting into Java programming, having done some programming in Fortran, C and C++ many moons ago. I'm trying to calculate Cos and Sin of an angle but it seems I need 'Math.class' to get it to work. I've found quite a lot of info on different websites about the class and what it does, but nowhere have I found a download link. Can anyone point me in the right direction please.
Thanks

I don't do much Java, well nothing in the past 4 years but have you tried...

import java.lang.Math.*

And use static methods such as Math.sin(x);

java.lang.* classes are automatically imported into your applications. So you don't need to list them explicitly.

Here is how to use it:

double s = 10.0;
double answer = Math.sin(s);

Apologies, too much C++ these days

Mr. Skidoodles

Thanks for that. I'm left scratching my head now. I had that line in my program and it wouldn't work. Some error relating to Math.class (can't remember exactly, there are so many of them). So I commented it out (// ) and continued. Now after deleting the // it works fine. Today must be a good day for it! Maybe it has Mondays off.
Thanks again.
