hi all!

Can anyone one explain me initailization sequence i.e. for

static variable
static block
static method
constructors
instance variable
instance block
instance method

and same for super class if we instansiate a subclass's object.
What can we use as Constroctor's body?

thanks

When run, the following output is produced:



Local variables in static and non-static methods are of course only initialized when the method is called.
The order of execution of static blocks and static variable initialization is depending on the code, as far as I know!
