Question

Can anyone please explain me in which scenario we use static initial block?

Answer 1

You can use it as a “constructor” for static data in your class. For example, a common situation might be setting up a list of special words:

private static final Set<String> special = new HashSet<String>();
static {
    special.add("Java");
    special.add("C++");
    ...
}

These can then be used later to check if a string matches something interesting.
