Provided below is Java source code (if you want, you could write your own version in Python) which as we have seen this week contains two threads that share a common variable, a boolean that represents that an item is produced and ready to be consumed. The program ran 20 times. Here is the count for each of the 20 runs and the average below. Here is the count for each of the 20 runs and the average: Run 1: 12 items produced Run 2: 14 items produced Run 3: 15 items produced Run 4: 11 items produced Run 5: 13 items produced Run 6: 10 items produced Run 7:9 items produced Run 8: 16 items produced Run 9: 12 items produced Run 10: 14 items produced Run 11: 15 items produced Run 12:11 items produced Run 13: 14 items produced Run 14: 9 items produced Run 15: 13 items produced Run 16: 12 items produced Run 17: 15 items produced Run 18:11 items produced Run 19: 13 items produced Run 20: 14 items produced Average items produced: (12+14+15+11+13+10+9+16+12+14+15+11+14+9+13+12+15+11+13+14)/20 = 12.4 For this lab turn in the following items in a word document: 1. "Reverse - engineer" the code to produce an Object Diagram for the Producer and the Consumer classes found in the lower portion of the code. (Ignore the CandP class, it is just the staging for the application.) 2. Using your common sense describe how you could improve the efficiency of this process in a few sentences.

Testing in a "BLACK Box" is what it means. What are the several variations on this theme?

For simple usage of GUIs, why would the source codes (shown below) not work?(a) The input/output objects have not been properly handled.(b) The data type of the methods has been defined in a wrong way.(c) The necessary parameters in the methods have not been assigned properly.(d) The flow of execution has been applied in a wrong way. import javax.swing.JOptionPane;public class Palindrome{public static void main(String[] args) //main method{long num1, num2; //variables to store the numbersString inputStr, outputStr; // strings to receive from the user// and displayinputStr=JOptionPane.showInputDialog("Enter the number: ");num1 = Long.parseLong(inputStr); // change the string tonum2 = num1; // numbersif (num1 <= 0){num1 = - num1; //if the numbers are negative, change the sign inputStr = inputStr.valueOf(num1);//change the inputStr value } if (isPalindrome(inputStr))outputStr = num2 + " is a palindrome";elseoutputStr = num2 + " is not a palindrome";JOptionPane.showMessageDialog(null,...

please write code in java Create a right triangle class with instance variables(double) for sideA, sideB and the hypo. write three constructors -the 2-param version assigns to sides A and B respectively. the 1-param version assigns the same value to both sides. the 0-param version assigns 10.0 to each side. the constructor also computes the hypotenuse based on the other two sides and saves that in the hypotenuse variable. Create accessors for all three variables. Write a toString() that will print/label the three sides. write some main code to create three instances of your class, one to test each of your constructors. you can input values or use fixed values. Display each instance using an implicit toString() call.

Draw the UML diagram for the class. Implement the class. Write a test program that creates an Account object with an account ID of 1122, a balance of 20,000,ドル and an annual interest rate of 4.5%. Use the withdraw method to withdraw 2,500,ドル use the deposit method to deposit 3,000,ドル and print the balance, the monthly interest, and the date when this account was created.

Below for each class you find a UML and description of the public interface. Implementing the public interface as described is madatory. There's freedom on how to implement these classes.The private properties and private methods are under your control.. There are multiple ways of implementing all these classes. Feel free to add private properties and methods. For each object, it's mandatory to create a header file (.h), implementation file (.cpp) and a driver. Blank files are included. The header should have the class definition in it. The implementation file should contain the implementations of the methods laid out in the header fine. And finally the Driver should test/demonstrate all the features of the class. It's best to develop the driver as the class is being written. Check each section to see if there are added additional requirements for the driver. Two test suites are included so that work can be checked. It's important to implement the drivers to test and demonstrate...

Hi, this is a java programming question with direction of what to do. I'm just gonna attach the question sheet. Implement the following class diagram (diagram in attached photo)setFirstName() method should set the firstName attribute of the class.setLastName() method should set the lastName attribute of the class.setSpecialization() method should set the specialization attribute of the Doctor class.setHealthnumber() method should set the healthNumber attribute of the Patient class.setIllness() method should set the illness attribute of the Patient class.If you are not comfortable with set methods, you are free to create your own constructors to set the attribute values.Create a HospitalApplication class which contains the main method. Inside the main method the following should be done in the order mentioned. (Any other ordering would not guarantee full marks).Prompt for the following inputs for 5 Doctors. (Use for loops)• First name• Last name• SpecializationValid specializations...

Can you help me with this please: Write the definition of a class swimmingPool, to implement the properties of a swimming pool. Your class should have the instance variables to store the length (in feet), width (in feet), depth (in feet), the rate (in gallons per minute) at which the water is filling the pool, and the rate (in gallons per minute) at which the water is draining from the pool. Add appropriate constructors to initialize the instance variables. Also, add member functions to do the following: determine the amount of water needed to fill an empty or partially filled pool, determine the time needed to completely or partially fill or empty the pool, and add or drain water for a specific amount of time, if the water in the pool exceeds the total capacity of the pool, output "Pool overflow" to indicate that the water has breached capacity. The header file for the swimmingPool class has been provided for reference. Write a program to test your swimmingPool class. An example of...

I need to change this code into object oriented code. here's how to objects are supposed to be setup. First you will need to make a Timer object. This object should function like a traditional stopwatch with methods for starting, stopping, resetting, and reporting back times. The design of the object itself is up to you (it should minimally contain methods for the aforementioned ideas), but it must consist of a solitary object that provides interfaces appropriate for being compositionally included as part of a sorting object to facilitate the time keeping portion of this exercise. Make sure you have a properly separated specification and implementation file for your Timer/Stopwatch object. The second object you will make should be a data housing object that has methods that enable client code to read in the formatted contents of data files, house the data in memory, and execute bubble sort, selection sort, and insertion sort algorithms in a timed fashion with the assistance of your...

or this assignment, you will select either the Cat or the Dog Java class from the UML diagram. Open the Virtual Lab (Apporto) by clicking on the link in the Virtual Lab Access module. Then open your Eclipse IDE and create a new class. Use the Eclipse IDE Tutorial if you need help with creating a class in Eclipse. Before you begin, review the following UML Class Diagram, paying special attention to the attributes and behaviors of each class. As a note, though the diagram illustrates an inheritance relationship between the classes, the class you choose to implement does not have to inherit from the Pet class for the purposes of this assignment. You will learn more about implementing inheritance in later modules. Next, you will implement either the Cat or Dog Java class. Your class must meet all of the specifications from the UML Class diagram. Be sure to include the following in your Cat or Dog class: All attributes (variables) with appropriate data types. Note that the types are...

Please you can complete this part of my code almost done, I could not get the output. Please help me to fix this and add part 4 and 5. Part 4 instructions (please see image attached): Implement the relationship between interface and the classes as shown in the diagram below. You must correctly implement appropriate methods in your classesbased on abstraction and interface principles. Part 5 instructions: . Inside the main() method of the Watch class, do the following:a) Create a new instance of the "AnalogWatch" class using the overloaded constructorand assign it to the object reference of type "Watch".b) Create a new instance of the "DigitalWatch" class using the overloaded constructorand assign it to the object reference of type "Watch".c) Display the content of both the objects.d) Display the current time using the two objects created above respectively Code: public abstract class Watch { //Data Fields private String brand; private String material; private double...
