Use the static initializer:

public class MyClass
{
    static {
    //init
    }
}

Can something similar be done in C++?
Actually, I need to initialize some variables, but I don’t want to create an object.

Answer 1

If the variables are static members, not only are you able to initialize them, but you must initialize them.

There’s no direct equivalent of Java initializer lists, but something similar can be done calling a function to initialize a static member:

class X
{
    static bool x;
}

bool foo()
{
    //initialization code here
}

bool X::x = foo();

This is for cases with intense logic. If all you want is to initialize static members, just do it similar to X::x.

Actually, I need to initialize some variables, but I don’t want to create an object.

If the variables are outside the class, initialize them directly (don’t need calling code for that).

If the variables are static members of the class, use one of the above approaches.

If the variables are non-static members, they simply don’t exist without an object.
