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.
Answer:
i) It is difficult to put the mouse pointer's insertion point in the text
ii) A gray border appear around the time and date when you point to it
Explanation:
When the date and time is pointed to or hovered using the mouse pointer, we have, that the background of the text changes to a grey border around the text when the date and time is inserted as a special object using the insert date and time button on the insert menu in the word processing application
The mouse pointer behaves different when working with some applications, and it could be difficult to place the insertion point of the mouse pointer in the text
Therefore, the correct options are;
<em>It is difficult to put the mouse pointer's insertion point in the text and</em>
<em>A gray border appear around the time and date when you point to it.</em>
The answer is "operating systems" brcause you need that that to use the rest

Answer:
SAN
Explanation:
A Storage Area Network (SAN) is a high-speed sub network of shared storage devices. A SAN's architecture works in a way that makes all storage devices available to all servers on a LAN or WAN. As more storage devices are added to a SAN, they too will be accessible from any server in the larger network.
