I'm reading a book "Thinking in Java" which says
objects are stored on heap and static variable are stored on some fixed location, saying it as static storage, so that they can be available for the entire time program when it is running.
class Myclass {
static int x =0; //stored on static storage
Myclass obj = new Myclass(); //stored on heap
}
Although making a object, static
will not be a good idea as far as OOP is concerned. Putting this aside for a while, there comes my questions:
class Myclass {
static Myclass obj = new Myclass(); //no man's land
}
All static content will be created on class load/initiation and stored in special location (most probably part of perm gen, differs based on implementation).
For second example, When your Myclass
is loaded, it's static content will be created/instantiated.
This tutorial may give you high level overview.
