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

if(a == 0 || b == 0)
{
//Then do something
}

Why not keep it readable? What is not concise about this? On the other hand,

a = (int)(Math.random()*5);

involves an unnecessary cast. Why not just use Random and invoke nextInt()?
