In the first case, myInt is incremented and the new/incremented value is passed to MyFunction (). In the second case, the old value of myInt is passed to MyFunction () (but myInt is still incremented before the function is called).

However it is best practice to initialize a value on a field so the most equivalent of the three options you listed is the third one: int myInt = 0 You cannot assign a struct (value type) to null as it is a non-nullable type.

What is the difference between "int myInt;" and "int myInt = 0;"

The assignment double myDouble = 4 contains a "primitive widening conversion", which takes the int literal 4 and widens it to a double, specifically, 4.0. Java usually doesn't allow implicit "primitive narrowing conversion" (the opposite), which is what myInt = myDouble; is attempting to do. However, you can make it explicit with a cast to int:

I'd love to be able to do this: class myInt : public int { }; Why can't I? Why would I want to? Stronger typing. For example, I could define two classes intA and intB, which let me do intA + int...

My problem is the addition between three and two, the compiler says: no suitable user-defined conversion from "Number" to "MyInt" exists I could solve this by implementing the overloading function in MyInt but since i want to support many classes like MyShort and MyFloat I would like to leave it in the Superclass. Is there any solution? Thanks!

In Go, if you define a new type e.g.: type MyInt int You can't then pass a MyInt to a function expecting an int, or vice versa: func test (i MyInt) { //do something with i } func main () { ...
