Explanation:
interface Runner
{
public abstract void run();
}
class Machine implements Runner
{
public void run()
{
System.out.println("Machine is running");
}
}
class Athlete implements Runner
{
public void run()
{
System.out.println("Athlete is running");
}
}
class PoliticalCandidate implements Runner
{
public void run()
{
System.out.println("Political Candidate is running");
}
}
class DemoRunners
{
public static void main (String[] args)
{
Machine m = new Machine();
m.run();
Athlete a = new Athlete();
a.run();
PoliticalCandidate pc = new PoliticalCandidate();
pc.run();
}
}
Answer:
Semaphores carries the signal between the task and interrupts that does not carry any type of additional data in the embedded system. A semaphore is used as synchronization object and helps in maintain the value between zero and the specific higher value.
It basically reduced the value each time and complete the semaphore object in the embedded system. Binary semaphores is the main type of semaphore that invoke activation of the task.
Answer:
Option C is the correct answer for the above question.
Explanation:
Pishing is a type of attack which is used by the attacker to access the secured information from the system. It is used by the third person assuming for the system that he is the right use of the system and can access the information of the system.
The above question asked about the attack which can access the information to assume that he is the right user and give accessed to the network to been hacked. So the answer is phishing which is described above. Hence option C is the correct while the other is not because:-
- Option A states about direct mail which is not a type of attack.
- Option B states about instant messaging which is also not a type of attack.
- Option D states about spam which is used to send the spam messages.
- Option 'E' states about the mass mail which is used to send the lots of spam mail.
Answer:
Option A (Kernal) seems to be the right answer.
Explanation:
- A Kernel appears to be the central component of such an OS. This handles machine as well as hardware activities, including most importantly storage as well as CPU power.
- This manages the majority of the initialization as well as program input/output requests, converting them into CPU data-processing commands.
The other given option are not related to the given circumstances. So that option A would be the right answer.
Answer:
- import java.util.Scanner;
-
- public class Main {
- public static void main (String [] args) {
-
- int jersey_num [] = new int[5];
- int rating [] = new int[5];
-
- Scanner inStream = new Scanner(System.in);
-
- for(int i=0; i < 5; i++){
- System.out.print("Enter player " + (i+1) + "'s jersey number:");
- jersey_num[i] = inStream.nextInt();
-
- System.out.print("Enter player " + (i+1) + "'s rating:");
- rating[i] = inStream.nextInt();
- }
-
- System.out.println("ROSTER");
-
- for(int j=0; j < 5; j++){
- System.out.println("Player " + (j+1) + "-- Jersey number: " + jersey_num[j] + ", Rating: " + rating[j]);
- }
- }
- }
Explanation:
The solution code is written in Java. Firstly create two array, jersey_num and rating, with int type. This is to hold the five pairs of numbers input by user (Line 6 -7).
Next, create a for loop that run for 5 iterations and in each iteration prompt user to input jersey number and rating (Line 11 -17). The input number and rating will be set to the array, jersey_num and rating, respectively.
Next, print the title "Roster" (Line 19).
Create another for loop to display the five input pair of values (Line 21 - 23).
