Consider the following class definitions.
public class Apple

{
public void printColor()
{
System.out.print("Red");
}
}
public class GrannySmith extends Apple
{
public void printColor()
{
System.out.print("Green");
}
}
public class Jonagold extends Apple
{
// no methods defined
}

The following statement appears in a method in another class.
someApple.printColor();
Under which of the following conditions will the statement print "Red" ?
I. When someApple is an object of type Apple
II. When someApple is an object of type GrannySmith
III. When someApple is an object of type Jonagold


a. I only
b. II only
c. I and III only
d. II and III only
e. I, II, and III

Answer:

Configure an automatic reply.

Explanation:

Dan's best option would be to configure an automatic reply. This reply will instantly be sent to any individual that messages Dan requesting a meeting. Once configured, Dan will no longer need to manually respond to each one of the messages and it will instead be handled automatically. These messages will also be automatically moved to the outbox where the messages that have been sent usually go.

Answer:

C

Explanation:

Which XXX declares a student's name.

public class Student {

   XXX

   private double myGPA;  

   private int myID;

   public int getID() {

        return myID;

   }

}

Group of answer choices

a. String myName;

b. public String myName;

c. private myName;

d. private String myName;

private String myName;

To declare a student's name, the following should be noted.

i. The name of the student is of type String

ii. Since all of the instance variables (myGPA and myID) have a private access modifier, then myName (which is the variable name used to declare the student's name) should be no exception. In other words, the student's name should also have a private access.

Therefore, XXX which declares a student's name should be written as

private String myName;

Option (a) would have been a correct option if it had the private keyword

Option (b) is not the correct option because it has a public access rather than a private access.

Option (c) is not a valid syntax since, although it has a private access, the data type of the variable myName is not specified.

Option (d) is the correct option.

Answer:

Electronic boards

Videoconferencing ability

Search engines

Cloud services

Computing softwares

Explanation:

Technology tools are used to simplify task bring ease, comfort as well as better satisfaction :

The use of electronic boards for teaching is an essential tool for students and educators alike as it provides great features aloowibg teachers to write and make drawings without hassle. This clear visual display goes a long way to aide student's understanding.

Videoconferencing breaks the barrier that distance and having to travel bring swhen it comes to learning. With this tools, students and educators can now organize classes without having to be physically present un the same class room.

Search engines : the means of finding solutions and hints to challenging and questions is key. With search engines, thousands of resources can now be assessed to help solve problems.

Cloud services : this provud s a store for keeping essential information for a very long time. Most interestingly. These documents and files can be assessed anywhere, at anytime using the computer.

Computing softwares : it often seems tune consuming and inefficient solving certain numerical problems, technology now p ovide software to handles this calculation and provides solutions in no time using embedded dded to codes which only require inputs.

Answer:

128 KB      

Explanation:

Given data :

The block size = 512 bytes

Block pointer size = 2 bytes

In an indexed allocation, a special block named Index Block contains all the pointers to the blocks that the file had occupied.

Therefore, the maximum number of block pointer in 1 block :

[tex]$=\frac{\text{block size}}{\text{pointer size}}$[/tex]

[tex]$=\frac{512}{2}$[/tex]

= 256

Thus, a block can hold maximum 256 pointers.

It is given the level of indexing is one. So,

Maximum size of the file =  maximum number of block pointers in 1 file x block size

                                          = 256 x 512

                                          [tex]$=2^8 \times 2^9$[/tex]

                                          [tex]$=2^{8+9}$[/tex]

                                           [tex]$=2^{17}$[/tex]

                                          [tex]$=2^7 \times 2^{10}$[/tex]

                                          [tex]$=128 \times 2^{10}$[/tex]

                                          = 128 KB   (∵ 1 KB = [tex]2^{10} \ B[/tex] )

Therefore, the largest file that 1 level if indexed allocation method can handle is 128 KB.
