1. Can you access an instance variable from a static method?
Explain why or why not.      1. Can you access a static variable
from an instance method? Explain why or why not.      2.
Consider the case where you have two classes, ClassA and ClassB,
such that ClassA contains a member variable defined as ClassB
myBobj. ClassB contains a constructor which takes a String
parameter. ClassA provides a constructor which accepts a String
parameter which is to be provided to myBobj. What needs to be
done to initialize the ClassB member variable with the value
from the ClassA constructor?      3. Here are some class
definitions with questions that follow.      public class
BaseClass { // methods of BaseClass }      public SomeClass
extends BaseClass      { // methods of SomeClass }      a.
SomeClass scobj = new SomeClass( );      b. BaseClass bcobj =
scobj;      c. SomeClass scobj2 = bcobj;      d.
bcobj.aMethodOfSomeClass( ); // does not exist in BaseClass
A. Is statement b above legal, or is casting required?
