Static Block in Java [duplicate]

Question

This question already has an answer here:

• What is the difference between a static and a non-static initialization code block 8 answers

I was looking over some code the other day and I came across:

static {
    ...
}

Coming from C++, I had no idea why that was there. Its not an error because the code compiled fine. What is this "static" block of code?

Answer 1

A static block executes once in the life cycle of any program, another property of static block is that it executes before the main method.
