Answer:
A. the BY statement.
Explanation:
The BY statement aids the procedure MEANS to develop the tree for the current BY group only, thereby analyze the stats, and clean the tree prior to the start and development of the next BY group.
However, without the BY statement, procedure MEANS develops its AVL tree for both the whole file and all sector estimates crossings established in CLASS.
Hence, in this case, the correct answer is the BY Statement.
Answer:
2. <em>A reference of type A can be treated as a reference of type B</em> - False
Base class or its objects are not related to their derived class (or its objects).
Explanation:
class A {
int a;
public A() {
a = 7;
}
}
class B extends A {
int b;
public B() {
b = 8;
}
}
///////////////////////////////////////////////////////////////////////////////////////////////////////
1. <em>After the constructor for class B executes, the variable a will have the value 7 </em>- True.
When an object of a derived class is declared, the constructor of base class is called before the constructor of derived class (is called).
3. <em>Both variables a and b are instance variables </em>- True.
Classes can have instance, or member, variables and methods.
4.<em> After the constructor for class B executes, the variable b will have the value 8</em> - True.
When object of class B is declared, its constructor was called, which initialized variable b to 8.
