java question (compilation problem)

[notfred]

I have this line of code:

long start = Calendar.getTimeInMillis();

the class imports java.util.* which includes the Calendar class.

When I try to compile it, I get the error:

"non-static method getTimeInMillis() cannot be referenced from a static context"

WTF? Nothing I have declared is static... why is it doing this?

getTimeInMillis() is not a static method, which means you can't use Calendar.getTimeInMillis(). You have to instantiate a Calendar object and call it from there.

Yep. You need to do:

Calendar myCal = new Calendar();
long start = myCal.getTimeInMillis();

Yeah... I jsut figured it out... and i tried it, and now it bitches about getTimeInMillis being protected. How the hell to I access a protected method of a class I didn't write?

Never mind... I think I got it.

Use java.long.System.currentTimeMillis()

It is static, and you can call it like in your first post.
