Concept of Pointer Parameter

Pointers are the special variable that stores the variable address, instead of storing the variable value. Pointer is a powerful feature of a programming language. A pointer is mostly used to save memory space and improve execution time.

**11.8 (New Account class) An Account class was specified in Programming Exercise 9.7.
VideoNote
Design a new Account class as follows:
New Account class
1 Add a new data field name of the String type to store the name of the
customer.
1 Add a new constructor that constructs an account with the specified name, id,
and balance.
I Add a new data field named transactions whose type is ArrayList that
stores the transaction for the accounts. Each transaction is an instance of the
Transaction class, which is defined as shown in Figure 11.6.
The get and sat methods for these data
fields are provided in the class, but omitted in the UML
diagram for brevity.
Transaction
-date: java. util.Date
The date of this transaction.
-type: char
The type of the transaction, such as "w for withdrawal.
*D" for deposit.
-amount: double
The amount of the transaction.
-balance: double
The new balance after this transaction.
-description: String
The description of this transaction.
+Transaction (type: char,
amount: double, balance:
double, description: String)
Construct a Transaction with the specified date, type.
balance, and description.
FicURE I1.6 The Transaction class describes a transaction for a bank account.
I Modify the wi thdraw and deposi t methods to add a transaction to the
transactions array list.
- All other properties and methods are the same as in Programming Exercise 9.7.

(JAVA) What is the benefit of an abstract class? Group of answer choices A) There is a guarantee that all classes that inherit from the abstract class have the methods and fields of the abstract class. B) They cannot be instantiated, so you only need to write the code for the fields and methods that are common to all classes that extend it. You also need to initialize those fields in a constructor. C) All choices are correct. D) All classes that extend the abstract class will automatically inherit all the methods from the abstract classes without need to implement them again.
What are the three things you need to do when working with classes that include pointer variables as member variables?
Question 5 (6 marks) Given the following interface class interface Bigoperation { public Biglnteger operation (Biglnteger x, Biglnteger y); Write Lambda expressions to implement BigOperation to simulate three arithmetic operations *, / and % on Biglnteger. You can call them op1, op2 and op3 respectively. Note that the three operations in Biglnteger are called multiply, divide and remainder respectively. Using these three operations, we wish to multiply all the digits in a Biglnteger. For example, if the Biginteger is 234, the product is 2* 3*4 = 24. The method has the following method heading: static BigInteger product (Biglnteger n, BigOperation op1, BigOperation op2, BigOperation op3) Compare the implementation of this method using two approaches: Iterative and Recursive. Put the Lambda expressions in a main method. Construct a few Biglnteger objects, invoke the methods to test our design. The following shows some of the sample outputs:
Instructions-Java Assignment is to define a class named Address. The Address class will have three private instance variables: an int named street_number a String named street_name and a String named state. Write three constructors for the Address class: an empty constructor (no input parameters) that initializes the three instance variables with default values of your choice, a constructor that takes the street values as input but defaults the state to "Arizona", and a constructor that takes all three pieces of information as input Next create a driver class named Main.java. Put public static void main here and test out your class by creating three instances of Address, one using each of the constructors. You can choose the particular address values that are used. I recommend you make them up and do not use actual addresses. Run your code to make sure it works. Next add the following public methods to the Address class and test them from main as you go: Write getters and…
17. Create a class ShuffleCipher that implements the interface MessageEncoder, as described in Exercise 15. The constructor should have one parameter called n. Define the method encode so that the message is shuffled n times. To perform one shuffle, split the message in half and then take characters from each half alternately. For example, if the message is abcdefghi, the halves are abcde and fghi. The shuffled message is afbgchdie. (Hint: You may wish to define a private method that performs one shuffle.)

(Java) The Abstract Art Class Write an abstract class as follows: The class is named Art It inherits from the Comparable interface It has a private String member variable named name It has a private String member variable named artist It has a private int member variable called year It has a default constructor that assigns the values "No name" to name, "No artist" to artist and -1 to the year. This default constructor calls the three argument constructor. It has a three-argument constructor to assign values to the name, artist and year variables. It has a copy constructor that makes a copy of another non-null Art object It has getters and setters for the name, artist and year variables It has a toString() method that creates a string of artist, with name and year tabbed once on subsequent lines (see sample output) It has an equals method that compares this Art to another Object It has a compareTo method that compares in this order: 1) artist, 2) name, 3) year This class contains no…
g) Make a class Class (as in a class of students, not a class as in a class of objects) that stores several Student objects. Store a list of students in an attribute called students. The initializer method should initialize the class as an empty class (no students). Implement a method add_student() that takes an object of class Student and adds it to class. Implement method pass_rate() that determines the fraction of students that pass the class (have a grade of >= 6). python code!!
