if()

To start, I'm pretty new to this so bear that in mind if I'm asking anything stupid here.

I'm trying to use if() to act upon int x being a certain value. Problem is, I can only ask if x is bigger than, or smaller than a particular value, not equal to. If I try something like:

if(x = 2)

then it returns the error "cannot convert from int to boolean, presumably because processing thinks I'm specifying the value of an integer in the middle there.

if(x < 2)
or
if(x > 2)

work fine, but how do I go about asking if something is exactly the value I want?

cheers!

You're looking for "==", as in:
Code:
if (x == 2) {
  // blah blah blah
}

(A lot of languages use just "=" for both assignment and equality testing, but Java isn't one of them.)
