Software Requirements: • Latest version of NetBeans IDE • Java Development Kit (JDK) 8 Procedure: 1. Create a public class named Monday. This class shall contain the main method. 2. Define an interface (without a modifier) named Alarm. This interface shall contain two (2) void methods named setAlarm() and showAlarm(). The setAlarm() method has a String parameter named time. 3. Add two (2) classes without modifiers named Weekday (abstract) and Monday. 4. For the Weekday class, implement the Alarm interface. Leave this class empty. 5. Set Weekday as the parent of Monday. Import Scanner from java.util and LocalTime from java.time. For showAlarm(), add these two (2) statements: LocalTime alarm = LocalTime .parse(time); LocalTime now = LocalTime.now(); Explanation: parse() converts String to time, while now() obtains the current time. 7. The output shall ask the user to enter the time for the alarm. If the time entered is past the current time, then display "Alarm is set for tomorrow!"; otherwise, display "I'll wake you up later!".

Problem Description and Given Info For this assignment you are given the following Java source code files: IStack.java (This file is complete – make no changes to this file) MyStack.java (You must complete this file) Main.java (You may use this file to write code to test your MyStack) You must complete the public class named MyStack.java with fields and methods as defined below. Your MyStack.java will implement the IStack interface that is provided in the IStack.java file. You must implement your MyStack class as either a linked list or an array list (refer to your MyArrayList and MyLinkedList work). Your MyStack must not be arbitrarily limited to any fixed size at run-time. UML UML CLass Diagram: MyStack Structure of the Fields While there are no required fields for your MyStack class, you will need to decide what fields to implement. This decision will be largely based on your choice to implement this MyStack as either an array list or a linked list. Structure of the Methods As…
Describe how you can use an interface as an alternative to a class to specify the type for a parameter.
In java language on netbeans design a console application that will print the game sales for a particular game in 2021. Use an abstract class named Games that contains variables to store the game name, game genre and the total sales. Create a constructor that accepts the game name, game genre and the total game sales as parameters. In this class also create get methods for the variables. The Games class must implement an iGames interface that contains the following: public interface iGames { public void printSales(); public String getGame(); public String getGameGenre(); public int getGameSales(); } Create a subclass called Game Sales that extends the Games class. The Games Sales class must contain a constructor to accept the game name, game genre and total game sales as parameters. Then, write code for the Print Sales method, which prints the game sales report for 2021. Finally, write a Use Games class to instantiate the Games Sales class.

A cash processing company has a class called Account used to process transactions: Method/Constructor Description public Account (Client c) public boolean process (Transaction t) constaucts an account using client information processes the next transaction, returning true if transaction was approved, false otherwise Account objects interact with Transaction objects, which have many methods including: Method/Constructor Description returns the value of this transaction in pennies (could be negative, positive or zero) public int value() The company wishes to create a slight modification to the Account class that filters out zero-valued transactions. Design a new class called FilteredAccount whose instances can be used in place of an Account object but which include the extra behavior of not processing transactions with a value of 0. More specifically, the new class should indicate that a zero-valued transaction was approved but shouldn't call the process method in the Account class to…

Objectives: Use Javadocs to document a class and methods Design and write a Java class Use fields (instance variables) Write multiple constructors Write accessor methods Write mutator methods Use the this keyword Use string concatenation Round floating point numbers (using Math.round()) Use a Scanner object Description ProduceItem class For this project, you get to design and write a ProduceItem class that stores a description, cost and weight as fields. Include both a constructor without any parameters and one with parameters for the description (String), cost (double) and weight (double) (in that order). For the constructor without parameters, set the description to an empty string, the cost to 0.0 and the weight to 0.0. Include appropriate accessor and mutator methods (and label them with comments including the terms "accessor" or "mutator"). So that the test cases compile, name the accessor methods: getDescription() getCost() getWeight() Additionally, name the mutator methods:…
Python Class and Objects 1. Create a class named "Account" and “Bank” 2. The class “Account” should have a parameter of id - integer type name - string type balance - float type # (Optional) You may add more parameters for your convenience 3. Create a method for “Account” class: checkBalance(self) - this will show the Account's remaining balance or money withdraw(self, amount) - this will withdraw an amount from the Account deposit(self, amount) - this will deposit an amount from the Account # (Optional) You may add more methods like sendMoney() etc.
True or False ___(1) An abstract class can have fields. ___(2) You can create an object from an abstract class _ _(3) An abstract class can have both abstract methods and methods that have method body
Object adapters and class adapters each provide a unique function. These concepts are also significant due to the significance that you attach to them.
Design/code/test a Java program containing an abstract the class absWelcome. This class should contain: 1. A public abstract void method (you name it) that is empty 2. A public regular method (you name it) that prints "Welcome to " Next, create a subclass clsHello that extends absWelcome. This class should contain: • A public regular method (you name it) that prints "Java Programming" Finally, inside the Main class create an object (you name it) from the clsHello class. Use this new object reference to: 1. Output "Welcome to " from the abstract class 2. Output "Java Programming" from the subclass Your output should resemble that shown below >sh -c javac -classpath -type f-name '*.java') java -classpath :targe Welcome to Java Programming
