}

static
{
System.out.println("3");
}

public static void main(String[] args)
{
new Question10();
}
}
Ans: is 3,2,1.
Hi all,
as of my knowledge static block will execute first in the above program but why is it printing the statement about the static block before the constructor block?
According to me it should print 3,1,2. Please help me

Hi,

Welcome to JavaRanch!

There are three print statements in the above. In order, they appear in (1) the constructor, (2) an initializer block, and (3) a static initializer block. Static initializer blocks are executed right after a class is loaded, so that's why "3" is printed first. The other initializer blocks are inserted into each constructor, right after the "super" call and before the statements in the body of the constructor; that's why "2" is printed next, as it's the first thing that happens in the constructor.
