Question

If I create a static block and create an Object there, say of some other class, will the object be created on the heap or on the stack?

class Hello {
   static {
       Abc abcObject=new Abc();
   }
   // Other Code...
} 

Answer 1

The object is created in the heap, but the reference to the object is in the stack.

The variable abcObject which you created is located in the stack. This contains a memory address within the heap where the new Abc() object is stored.
