Is there a simpler way to check multiple values against one value in an if-statement?

Question

Basically, what I want to do is check two integers against a given value, therefore, classically what you would do is something like this:

//just to get some         


        

Answer 1

For this example, you can do

if (a * b == 0)

or for more variables

if (a * b * c * d == 0)

while more concise it may not be as clear. For larger values, you need to cast to a long to avoid an overflow.
