How Are New Objects Allocated?

Question

Let's say your have:class MyClass {
  int mOnlyMember;
  public void method1() {
    //a huge complex method body
}When you create a new instance of MyClass, I know new memory is allocated for mOnlyMember, but is new memory also allocated for method1()? That is, does each object have it's own copy of the method? More to the point, when I create a new instance of MyClass, is it expensive (because the method body is so complex) or is it cheap (because there's only a single int member)?
Thanks for any clarification,
Johh

Answer 1

i'm not very sure about the memory allocate for
method.... but, it should be allocate for the method
too...Er, no. The code of the method body exists only once
per class. All the instances (the objects you create)
share the same code. Each instance (object) has its
own copy of instance (non-static) member variables,
and each method invocation has its own copy of the
variables that are local to that method.
Okay... learned.... :)

however, creating an new instance is expensive... we
normally will try to reuse an instance ifpossible...
Um, you might want to recheck your facts on this.
