Are arithmetic operations on literals calculated at compile time or run time?

Question

I have the following:

double timeInMinutes = (double) timeInMilliseconds / (1000 * 60); 

Is the operation (1000 * 60) done at compile time or at run time? In other words, are there performance differences during run time between the code snippet above and:

double timeInMinutes = (double) timeInMilliseconds / 60000; 

EDIT: my question is different from Will the Java compiler precalculate sums of literals?, as I'm mixing the use of variables and literals in the arithmetic operations. It's a small difference, but as @TagirValeev noted in the comments (Are arithmetic operations on literals calculated at compile time or run time?), there are instances where some literals aren't pre-compiled even though they could be.

Answer 1

As per JLS §15.2 - Forms of Expressions

Some expressions have a value that can be determined at compile time. These are constant expressions (§15.28).

Multiplicative operators like *, /, and % falls under constant expressions, so it would be determined at compile time.

@SergeyMorozov was faster than me to write and get byte code proof (#2 = Integer 60000) but here is the practical proof and above is theoretical/official statement:

Try generating byte code at your end as well using 1000 * 60 and 60000, and you will see same byte code instructions, and hence there would be same runtime performance.

Java class:

public class Test {     public static void main(String[] args) {         int compileTest = 1000 * 60;     } } 

Byte code:
