In what order do static/instance initializer blocks in Java run?

Question

Say a project contains several classes, each of which has a static initializer block. In what order do those blocks run? I know that within a class, such blocks are run in

Answer 1

http://docs.oracle.com/javase/tutorial/java/javaOO/initial.html

kindly check java documentation.

then clearly mentioned no matter how may static blocks are there they will be executed as a single block in the order they appear

So,

My understanding here is java is looking your code as

static{
i=1;
i=2;
}

static int i;

that is why you are getting output 2

hope this is helpful

Answer 2

Initialization of a class consists of executing its static initializers and the initializers for static fields (class variables) declared in the class.

Initialization of an interface consists of executing the initializers for fields (constants) declared in the interface.

Before a class is initialized, its direct superclass must be initialized, but interfaces implemented by the class are not initialized. Similarly, the superinterfaces of an interface are not initialized before the interface is initialized.
