Implement a class named MyArrayList that extends class the java.util. ArrayList. The class MyArrayList overrides the add(obj) method in the following way: it adds obj into the list if the object does not occur in the list or it occurs in the list only once; otherwise, if the object occurs in the list more than once, then the method does nothing.

I wrote my code in python 3.8. I hope this helps

Answer:

The program in Python is as follows:

from operator import itemgetter

m = int(input("Number of records: "))

print("Name, Age, Score")

my_list =[]

for i in range(m):

   user_details = input()

   my_list.append(tuple((user_details.split(","))))

my_list.sort(key =  itemgetter(0, 1, 2))        

print("Sorted: ", my_list)

Explanation:

This imports the operator function from itemgetter

from operator import itemgetter

This gets the number of records, m

m = int(input("Number of records: "))

This prints the format of input

print("Name, Age, Score")

This initializes the list of tuples

my_list =[]

This iterates through m

for i in range(m):

This gets the details of each person

   user_details = input()

This appends the details to the tuple

   my_list.append(tuple((user_details.split(","))))

This sorts the tuple

my_list.sort(key =  itemgetter(0, 1, 2))        

This prints the sorted tuple

print("Sorted: ", my_list)

Once all the marks are entered the program prints out the highest mark among all of them. The output can be seen in the attached picture below with a test of a couple of marks.

marks = []

for x in range(100):

   mark = int(input("Enter a mark: "))

   if mark == -1:

       break

   else:

       marks.append(mark)

print("Max value: " + str(max(marks)))

Answer:

The method in C++ is as follows:

double calcPyramidVolume(double baseLength, double baseWidth, double pyramidHeight){

   double baseArea = calcBaseArea(baseLength, baseWidth);

   double volume = baseArea * pyramidHeight;

   return volume;    

}

Explanation:

This defines the calcPyramidVolume method

double calcPyramidVolume(double baseLength, double baseWidth, double pyramidHeight){

This calls the calcBaseArea method to calculate the base area of the pyramid

   double baseArea = calcBaseArea(baseLength, baseWidth);

This calculates the volume

   double volume = baseArea * pyramidHeight;

This returns the volume

   return volume;  

}

Answer:

Following are the constructor to the given code:

Bug(int position) //defining a constructor that defines a integer parameters

{

       this.position = position;//use this key word to hold parameter value

       right = true;//defining a variable right that hold a boolean value

   }

Explanation:

In this code, a constructor is declared that defines integer parameters with it, Inside the constructor, this keyword is used to holds the "position" parameter value and defines a boolean variable "right" that holds a boolean value.

Full program:

public class Bug //declaring a class Bug

{

   private int position;//declaring integer variable position

   private boolean right;//declaring boolean variable

   public Bug(int position) //defining a parameterized constructor

   {

       this.position = position;//use this to hold position value

       right = true;//holding boolean value

   }

   public void turn() //defining a method turn

   {

       right = !right;//holding value

   }

   public void move() //defining method move

   {

       if(right)//use if to check boolean value

       {

           position++;//incrementing position value

       }  

       else//else block

       {

           position--;//decreasing position value

       }

   }

   public int getPosition()//defining method getPosition  

   {

       return position;//return position value

   }

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

   {

       Bug bug = new Bug(10);//creating class object

       System.out.println("Expected = 10, Actual = " + bug.getPosition());//calling method with printing value

       bug.move();//calling method

       System.out.println("Expected = 11, Actual = " + bug.getPosition());//calling method with printing value

       bug.move();//calling method

       bug.move();//calling method

       bug.move();//calling method

       System.out.println("Expected = 14, Actual = " + bug.getPosition());//calling method with printing value

       bug.turn();//calling method

       bug.move();//calling method

       bug.move();//calling method

       System.out.println("Expected = 12, Actual = " + bug.getPosition());//calling method with printing value

Explanation:

Answer:

Explanation:

To maintain data consistency and integrity in a large multi-user system, transactions are completed concurrently with the aid of concurrency management techniques.

The following are some of the benefits of concurrent transaction processing and execution versus serial transaction processing and/or execution:

Improved Resource Usage:

A transaction frequently combines both CPU and Input/output activities, resulting in better resource usage. Computers have the ability to run disks and CPUs in parallel. As a result, transactions can also be executed in parallel, with one employing the usage of the CPU and the other using the disk. As a result, resources are better used than in serial transaction processing and execution.

Improved throughput:

Running transactions in parallel has an immediate impact of increasing throughput since a greater number of transactions can be completed in the same period of time.

Lower/shorter waiting time:

Reduced wait time: When transactions are processed sequentially and serially, a short transaction is forced to wait for a longer transaction. Because transactions usually affect distinct portions of the database. As such, it's best if they happen at the same time i.e it is run concurrently.

The characteristics listed above are critical to a system's performance.

Thus, It is obvious that the benefits of concurrency exceed the extra programming work necessary to execute transactions concurrently. As a result, database systems must handle concurrent transactions despite the additional work necessary since it is worthwhile.

D. Creating mutiple goals.

Explanation:

Answer:

Physical design.

Explanation:

Systems development life cycle (SDLC) is a strategic process that involves determining the overall system architecture, which is typically comprised of hardware, end users, physical processing components, software, and the communication channel that will effectively and efficiently satisfy the essential requirements of the system.

The system inputs and outputs is typically designed along with a plan of how the system's features will be navigated.

Basically, system design is divided into two (2) categories and these includes;

I. Logical design.

II. Physical design.

Furthermore, the design of service systems involves the process of planning, creating infrastructure, building communication, organizing staffs and standardization of a system so as to improve its quality and business relationships between the service provider and its clients.

In the physical design of systems development life cycle (SDLC), broad, user-oriented systems requirements are obtained from end users by companies and then translated into the detailed specifications that would be used to create a fully developed system.
