Why does the part between line 2 to 4 executes first when we know that Constructor gets invoked first always ?

Question

When I remove the curly braces from print statement between line 2 and 4, the code produces error.
I know that print statement cannot be used inside class.
But I wasn't able to figure out why it works when print statement is surrounded by curly braces inside a class.

A detailed explanation or a reference to the answer of the problem would be amazing :)

Answer 1

Because it is wrong that the constructor comes first.

In your case:

{
System.out.println("Instance Init");
}

This block is called an instance block. It gets executed when you create an instance of your class. And it is executed before constructor.

static{

}

This one is a static block. It gets executed when the class is loaded and before instance block+constructor.

I hope this code helps you:
