Challenge 3: Scores.java and TestScores.java
Implement a Scores class. The class constructor should accept an array of scores as its argument. The class should have a method that returns the average of the scores. If any score in the array is negative or greater than 100, the class should throw an IllegalArgumentException.
Implement a TestScores class that creates an array and fills it with numbers given by the user. It should catch the exception thrown when the user enters an illegal value.
You are required to design an item class which has following attributes
String name;
Int stock;
Int price;
String expiry_Date;
Provide default & Parameterized constructors.
Provide getters & setters for data members.
Provide a toString() method to print values.
Now create an array of items store values in it (take values form user). After that you have to print the following
All the items in the array.
items whose name starts with ‘a’;
All sold out items (whose stock is zero).
All the items having expire date before 2-11-2020.
Solve this using Simple java, arrays in java and string methods if required.
1. Declare an array to save 4 Dog objects. The Dog class is provided below. Look into the Dog class and find what attributes are needed for a dog object. Then initialize five dogs with the following information:
Lily, 5 years old
Jacob, 2 years old
Sugar, 8 years old
Bush, 3 years old
2. Print out every dog using a for loop (use either regular for loop or for-each loop, your choice). But you may find when you print out, the name and age are not displayed. Why?
3. Fix this problem by implementing the toString method in the Dog class.
Dog Class:
public class Dog { private String name; private int age;
public Dog(String name, int age) { this.name = name; this.age = age; } public void setName(String name) { this.name = name; }
}

Use this to design and implement a class called DeckOfCards that stores 52 objects of the Card class using an array. Include methods to shuffle the deck, deal a card, return the number of cards left in the deck, and a toString to show the contents of the deck. The shuffle methods should assume a full deck.Create a separate driver class that first outputs the populated deck to prove it is complete, shuffles the deck, and then deals each card from a shuffled deck, displaying each card as it is dealt along with the number of cards left in the deck.

- In this version, you are to reimplement the functionality of version 1, but this time using the classes you coded in Lab 3. The basic output is identical to that of version 1, but now: The three parallel arrays are gone — replaced with a single array of type PhonebookEntry. You should be reading in the entries using the read method of your PhonebookEntry class (which in turn uses the read methods of the Name and PhoneNumber classes). Use the equals methods of the Name and PhoneNumber classes in your lookup and reverseLookup methods. Use the toString methods to print out information. Make 100 the capacity of your Phonebook array Throw an exception (of class Exception) if the capacity of the Phonebook array is exceeded. Place a try/catch around your entire main and catch both FileNotFoundExceptions and Exceptions (remember, the order of appearance of the exception types in the catch blocks can make a difference).

Once created the list is fixed (none of the items can be changed, no items can be added or removed, the order is fixed). Use an array to store your list. Your class will have a single constructor that takes an array of ints as input that will be used to specify the constant list. You must provide appropriate methods to give the user of your class access to the list elements. A user should be able to access individual elements (by position) and the entire list of numbers. Your class must use encapsulation. Explain how your solutions solves the problem. That is, explain why your ConstantList really is a constant list of numbers.arrow_forwardWrite a Program to define a Mobile class, with member variables String brand; double price String OS (make it Final). Float memory Make a default constructor, Make a parameterized constructor. Overload the above Constructor. Provide getters and setters for data members. Inside main, create an array of mobiles.

- Write a method in your ArrayUtilities class that meets the following requirements: - It should be named "counts".] - It should declare a parameter for an int array. You may assume that the array will contain only non-negative values. - It should return an int array where the value at each index is the count of how many times the index appears in the original array . For example, if the original array contained the value 10 3 times, then the value at index 10 in the count array should be 3. - Hint: the size of the array is determined by the maximum value in the original array. If the original array is empty, the count array should also be empty. A more detailed example: Given the int array [1, 2, 3, 4, 4, 1, 1, 2, 0, 6], your function would return the array [1, 3, 2, 1, 2, 0, 1]. The value at each index indicates how many times the index appears in the original array. The value at index 0 is 1 because 0 appears 1 time in the original array. The value at index 1 is 3 because 1 appears 3…arrow_forwardThe following is the specification for the constructor of a EmailFolder class: /*** Creates a new EmailFolder with the given label** @precondition label != null AND !label.isEmpty()* @postcondition getLabel()==label*/public EmailFolder(String label) Assume the variable folders is an array list of EmailFolder objects.

- Create an object called GSSArray. (It stands for growable self-sorting array)This object will manage an array of type int. Create a private variable for an array of type int. In the constructor for this object, take in an int value which will determine the starting size of the array. The constructor should also instantiate the array.Create a public method called insert, which will take in an int and find the location in the array where it belongs and insert it there. If the array is full, then before inserting the value, method insert should call private method increaseSize, which will create a new array which is double the size of the current array. Then it will copy the values from the original array into the new array and set the private variable to this new array.The array should keep track of how many of its indexes are filled. Create a private variable called lastindex which will be equal to the last index of the array that has a value.Create a public method delete, which will…arrow_forwardCreate a new class, called ConstantList that stores a "constant" list of integers (ints).Dnce created the list is fixed (none of the items can be changed, no items can be added or removed, the order is fixed).

Create a java version of this game with the following requirements. Extend the JPanel class and create an array of 52 cards. Add four sets of numbers from 1 to 10. Use J for Jack, Q for queen, K for king, and A for ace. Jack through king will have a value of 10, and the ace will have a value of 11. Deal two cards to the user and two cards to the computer. Do not show the value of the computer's first two cards to the user. Add buttons Hit, Stay, and Reset. If the user selects the "Hit" button, randomly select one of the cards from the array, and give it to the user. (After selecting a card, do not reuse this index during the rest of the game.) If the dealer has less than 21, "hit" the dealer, too. When the user selects the "Stay" button, add up the card values. The winner is the person who is closest to 21 without going over. Name the class Blackjack.java.arrow_forward
