Chapter 17, Problem 7PC
Program Plan Intro
Generic class to find out largest, smallest, total and average of elements in an ArrayList
Program plan:
- Import the required package.
- Create the class “MyList” with a type parameter “T” that is constrained to an upper bound Number using the keyword extends,
- Create “ArrayList” as a field of class “MyList” with type parameter “T”.
- Define the constructor.
- Define the public method “add()” to accept the parameter of type “T”,
- Store the value in “ArrayList” using the reference variable “list”.
- Define the method “largest()”,
- Call the method “get()” to store the initial value of “ArrayList” in the variable.
- Iterate the elements of “ArrayList” using “for” loop and compare each value using if statement to find the largest value in the “ArrayList”.
- Return the largest value using the keyword “return”.
- Define the method “smallest()”,
- Call the method “get()” to store the initial value of “ArrayList” in the variable.
- Iterate the elements of “ArrayList” using “for” loop and compare each value using if statement to find the smallest value in the “ArrayList”.
- Return the smallest value using the keyword “return”.
- Define the method “Total()”,
- Call the method “get()” to store the initial value of “ArrayList” in the variable.
- Iterate the elements of “ArrayList” using “for” loop and calculate the total value of elements in the “ArrayList”.
- Return the total value using the keyword “return”.
- Define the method “Avg()”,
- Call the method “get()” to store the initial value of “ArrayList” in the variable.
- Iterate the elements of “ArrayList” using “for” loop and calculate the total value of elements in the “ArrayList”.
- Calculate and return the average value using the keyword “return”.
- Create the class “Main”,
- Define the method “main()”,
- Create the object of a class “MyList” as a type of “Integer”.
- Call the “add()” method to fill the values in the “ArrayList”.
- Call the method “largest()” to print the largest value of “ArrayList”.
- Call the method “smallest()” to print the smallest value of “ArrayList”.
- Call the method “Total()” to print the total value of elements in the “ArrayList”.
- Call the method “Avg()” to print the average value of elements in the “ArrayList”.

Library class:
Fields: books as arraylist to store all the books available in the library
B3
B1
B2
В4
B5
Constructor:
Library()
}
: No parameterized constructor to create the books object
Methods:
1. addBook(Book bookobj): to add a new book to the arraylist; send the book object as a
parameter to this method.
2. searchBook(String name): search a book by a given name in the arraylist. if exits print
bookX found; otherwise print not found!!!
3. RemoveBook(String name): to delete a book object from arraylist by a given name:
Hint: you need to use iterator class and remove method.
Book class:
Fileds: bookld, bookname.
Constructor: two parameterized constructor that accepts name
a parameter
Book(int ID, String name)
.....
Methods:
1. Accessor method to return the name of the book
2. Mutator method to change the id of the book.
Use this Main method: in your program:
public static void main(String args[])
{
Library lib=new Library();
lib.addBook(new Book("b1"));
lib.addBook(new Book("b2"));…
Make Album in c++
You are going to develop a new class named Album. This class will has (at a minimum) teh following attributes and features:
Attributes:
Album Title
Artist Name
Array of song names (Track Listing)
Array of track lengths (decide on a unit)
At most there can be 20 songs on an album.
Behaviors:
Default and at least one argumented constructor
Appropriate getters for attributes
bool addTrack(string name, type duration) - adds track to album. You decide type on duration. Make sure you document what dis is.
getAlbumLength() - method dat returns total length of album matching watever units / type you decide.
getAlbumLength_string() - method dat returns total length of album in mm:ss format string. I would suggest using you're other getLength function here.
string shuffleAlbum(int n) - method dat returns a formatted string made up of n random tracks from teh album.
The string will be in the format [1] track_name (mm:ss), [2] track_name (mm:ss)...
Well formatted print()…

- The interface Range is defined below:public interface Range{ void setLimits(int x, int y); int getNumber();}Implementations of Range should exhibit the following behaviour:• The setLimits method should store its parameter values somewhere to serve as the lower and upper limits of the range appropriately.• A call to getValue should return an integer that is always greater than or equal to the lower limit and less than or equal to the upper limit.The class RandomInteger is an implementation of the interface Range. It also has the following features:• It has two fields of int type, low and high, to record the lower and upper limits of the range, respectively.• It has single constructor method that takes two integers and stores them in the appropriate fields. Note: You should make use of the setLimits method.• A call to the method getNumber should return a random number that is always within the range, i.e. greater than or equal to the lower limit and less than or equal to the upper limit.…arrow_forwardA class object can encapsulate more than one [answer].arrow_forwardJava Programming: ConWay World Conway’s game of life is a simple simulation of life forms in a two dimensional grid. The ConwayCell implements the standard behavior of a call in Conway’s Game of Life. You only need to implement and test two new classes. You will create two different cells, derived from AbstractCell. 1. Alternating Cell The first class that you should create is a class named AlternatingCell. This is a cell that should alternate between being alive and dead with each generation. Add one or more of your AlternatingCells to your ConwayWorld. You can see how to add a cell in line 15 - 20 of Main.java. Give your AlternatingCell a unique display character when it is alive so that you can see it in your conway world. 2.
