Answer:

B. installApplication(‘A’, 1);

Explanation:

Given

The above code segment

Required

The correct call to installApplication

The function installApplication is declared as void, meaning that it is not expected to return anything.

Also, it receives a character and an integer argument.

So, the call to this function must include a character and an integer argument, in that order.

Option D is incorrect because both arguments are integer

Option C is incorrect because it passes no argument to the function.

Option A is incorrect because it receives an integer value from the function (and the function is not meant not to have a return value).

Option B is correct

Main memory is a fast storage and it can be accessed directly by the CPU. For a program to be executed, it should be first loaded in the main memory. An Operating System performs the following activities for memory management:  

It keeps tracks of primary memory, i.e., which bytes of memory are used by which user program. The memory addresses that have already been allocated and the memory addresses of the memory that has not yet been used. In multi programming, the OS decides the order in which process are granted access to memory, and for how long. It Allocates the memory to a process when the process requests it and deallocates the memory when the process has terminated or is performing an I/O operation.

b. The constructor for the parent class is called.

Explanation:

In this case this specific piece of code is calling the constructor for the parent class. Since a MountainBike object is being created. This creation uses the MountainBike class constructor but since this is a subclass of the Bicycle class, the super() method is calling the parent class constructor and passing the variables startCadence, startSpeed, startGear to that constructor. The Bicycle constructor is the one being called by super() and it will handle what to do with the variables inputs being passed.

C. Spoofing.

Explanation:

Cyber security can be defined as preventive practice of protecting computers, software programs, electronic devices, networks, servers and data from potential theft, attack, damage, or unauthorized access by using a body of technology, frameworks, processes and network engineers.

Some examples of cyber attacks are phishing, zero-day exploits, denial of service, man in the middle, cryptojacking, malware, SQL injection, spoofing etc.

Spoofing can be defined as a type of cyber attack which typically involves the deceptive creation of packets from an unknown or false source (IP address), as though it is from a known and trusted source. Thus, spoofing is mainly used for the impersonation of computer systems on a network.

Basically, the computer of an attacker or a hacker assumes false internet address during a spoofing attack so as to gain an unauthorized access to a network.

Answer:

A.

the final keyword is used to denote constants. It can be used with variables, methods, and classes. Once any entity (variable, method or class) is declared final , it can be assigned only once.

B.

Static variables are declared in the same place as instance variables, but with the keyword 'static' before the data type. While instance variables hold values that are associated with an individual object, static variables' values are associated with the class as a whole.

Answer:

Following are the code to the given question:

import java.util.concurrent.*; //import package

public class Threads //defining a class Threads

{

private Integer s = new Integer(0);//defining Integer class object

public synchronized static void main(String[] args)//defining main method  

{

Threads t = new Threads();//defining threads class object

System.out.println("What is sum ?" + t.s);//print value with message

}

Threads()//defining default constructor

{

ExecutorService exe = Executors.newFixedThreadPool(1000);//defining ExecutorService class object

System.out.println("With SYNCHRONIZATION........");//print message

for(int i = 1; i <= 1000; i++)//defining a for loop

{

exe.execute(new SumTask2());//calling execute method

System.out.println("At Thread " + i +" Sum= " + s + " , ");//print message with value

}

exe.shutdown();//calling shutdown method

while(!exe.isTerminated())//defining while loop that calls isTerminated method

{

}

}

class SumTask2 implements Runnable//calling SumTask2 that inherits Runnable class

{

public synchronized void run()//defining method run

{

int value = s.intValue() + 1;//defining variable value that calls intvalue which is increment by 1

s = new Integer(value);//use s to hold value

}

}

}

Output:

Please find the attached file.

Explanation:

In this code, a Threads class is defined in which an integer class object and the main method is declared that creates the Threads class object and calls its values.

Outside the method, the default constructor is declared that creates the "ExecutorService" and prints its message, and use a for loop that calls execute method which prints its value with the message.

In the class, a while loop is declared that calls "isTerminated" method, and outside the class "SumTask2" that inherits Runnable class and defined the run method and define a variable "value" that calls "intvalue" method which is increment by 1 and define s variable that holds method value.

Dynamic Router

Explanation:

A dynamic router is a network connection device that can build tables that identify addresses on each network.

Dynamic networks are networks that vary over time; their vertices are often not binary and instead represent a probability for having a link between two nodes.

Statistical approaches or computer simulations are often necessary to explore how such networks evolve, adapt or respond to external intervention.

DNA statistical tools are generally optimized for large-scale networks and admit the analysis of multiple networks simultaneously in which, there are multiple types of nodes (multi-node) and multiple types of links (multi-plex).

Therefore, A dynamic router is a network connection device that can build tables that identify addresses on each network.

Answer:

The program in Java is as follows:

import java.util.*;

public class Main {

public static void removeDuplicate(ArrayList<Integer> list){

 ArrayList<Integer> newList = new ArrayList<Integer>();

 for (int num : list) {

  if (!newList.contains(num)) {

   newList.add(num);  }  }

 for (int num : newList) {

     System.out.print(num+" ");  } }

public static void main(String args[]){

 Scanner input = new Scanner(System.in);

 ArrayList<Integer> list = new ArrayList<Integer>();

 System.out.print("Enter ten integers: ");

 for(int i = 0; i<10;i++){

     list.add(input.nextInt());  }

 System.out.print("The distinct integers are: ");

 removeDuplicate(list);

}}

Explanation:

This defines the removeDuplicate function

public static void removeDuplicate(ArrayList<Integer> list){

This creates a new array list

 ArrayList<Integer> newList = new ArrayList<Integer>();

This iterates through the original list

 for (int num : list) {

This checks if the new list contains an item of the original list

  if (!newList.contains(num)) {

If no, the item is added to the new list

   newList.add(num);  }  }

This iterates through the new list

 for (int num : newList) {

This prints every element of the new list (At this point, the duplicates have been removed)

     System.out.print(num+" ");  } }

The main (i.e. test case begins here)

public static void main(String args[]){

 Scanner input = new Scanner(System.in);

This declares the array list

 ArrayList<Integer> list = new ArrayList<Integer>();

This prompts the user for ten integers

 System.out.print("Enter ten integers: ");

The following loop gets input for the array list

 for(int i = 0; i<10;i++){

     list.add(input.nextInt());  }

This prints the output header

 System.out.print("The distinct integers are: ");

This calls the function to remove the duplicates

 removeDuplicate(list);
