Object Creation Logic in Java

I am trying to understand the memory management scheme for JVM

Consider two classes A, B

Class A {

public A() {
//Do Something
}

}

Class B() extends A{

public B(){
super();
// DO something again
}
}

From main B b = new B();

As per my knowledge the Class loader will load A, B and will create 2 objects each. Is there any other object that would get created?

Also the second part of my question is that , while accessing Java Visual VM , I see objects of Java NIO package has been created. Is there any way I can prevent JVM from creating objects which are not related to my project?

The answer to your first question is that there will be only one object created. Basically, for every "new" statement, there is one object created. So I think your assessment about two objects being created is wrong.

Secondly, I do not think you have any control on the JVM with respect to the objects that are created (not related to your project).

Lastly, for a more detailed answer to the first part of your question you can take a look here
