Please correct me on this,its very confusing

Question

Please correct me if I am wrong somewhere. I have been taught,that

1. Every time a class is loaded, a class object is created in heap memory,and its reference by the name of Class is kept in class area
2. Each and every field,like string,int whatsoever is the is also stored in as objects and its reference is given in class object created
3. Same goes for method,constructor's etc

now there is a question also,whether all these thing is stored for every object or just one object is created to know about the information

Also do tell me What does this Field class in actual have? like for eg

class b
{
String s="sdnla";
}

and there are two objects of b class,b1 and b2,what does Field class object have?

Answer 1

In normal circumstances, there is just one Class object per class. Not per object. If Java created all that structure for every object, it would use enormous amounts of memory; far more than is actually needed.

If you are creating multiple classloaders within your application, then you may end up with multiple Class objects per class - one held by each classloader. But very few of us ever do such a thing. You might do this if you were programming an application server, or something of that type.
