Answer by Neil Coffey for which one is faster 5+5+5+5+5 or 5*5?
There are at least two questions here: the performance of the underlying operations, and what the compiler does. (In fact, what both the Java-to-bytecode compiler and the JIT compiler do.)Firstly, the...

It all depends on the environment you are using:Which compiler? Is it a good one, then it compiles it to constants.What's the rest of the program code? If the result is not used, it both compiles to...

We should compare time complexity. The function is f1(n) = n * c, the equivalent f2(n) = Sum[1->n] c.The complexity for multiplication is O(1) (constant time, one calculation for any n), the...

I guess Addition is faster than multiplication, because (as far as i know) all multiplications are treated as additionsAdded :read here for some explanation

In your case is does not change anything. Let's compile:public class Toto { public static void main(String[] args) { int a = 5 + 5 + 5 + 5 + 5; int b = 5 * 5; }}and check the decompilation...

It depends on compiler because each compiler having different mechanism for this some using left shift operation or some uses another mechanism.But in many cases addition is faster than multiplication.

Both are constant expressions, so they will be simplified to int a = 25;int b = 25;at compile time (100% sure, even toy compilers do this, as it is one of the simplest optimisations possible).In the...

It is platform (and compiler) dependent. If you need to know, then measure it. It's unlikely that you'll be in a situation where you need to know.However, in both your examples, these will be evaluated...

I don't know how to ask but just want to ask. help me to tag it please. Anyway, my friend asked me a question that which one is faster in Javaint a = 5 + 5 + 5 + 5 + 5orint b = 5 * 5 ?Is it language...
