Is a static var 'copied' when and object is cloned?

Question

HI,
If you have an abstract class that has a static object as a property,
i.e.
public abstract class xyz implements Cloneable, Runnable {
static Manager M;
Thread runner;
and a concrete class is created by cloning this object, i.e.
public void run(){
if(x!=null){ // if we are the server process
while (runner!=null){
try{
Concrete_xyz = (Concrete_xyz) clone(); // (Concrete xyz implements xyz)
Concrete_xyz.x = null;
Concrete_xyz.runner = new Thread(Concrete_xyz);
Concrete_xyz.runner.start();
}catch(Exception e){}
}else{
run(client);
will all the clones share the static Manager object? ....is this a stupid question?
any help much appreciated

Answer 1

Well, not a stupid one, just kinda obvious. There is one and only one copy of each static field for any loaded class. The only time there would be more than one is when more than one class loader loads the class, in which case the classes are truly the same (just happen to have the code).
Cloning, serialization/deserialization, etc. will never duplicate static fields.
