true of false: a) The first step in any programming task is to start coding. b) The only places we would ever want to put a comment in our code are above a method and above a class.
. Protected variables coth Task 1.1: Base Animai Create Animal Class with 3 protected attributes: • name - String • type-String • nocturnal - boolean • 4 public void Methods: • printInfo-should print: " is a(n) ." • printSleepInfo-should print: "s sleep during day." or "s sleep during night." • printRoam - should print: " walks around." • printFeed method - will implement in subclasses ● Subclass Owl: Constructor takes in name as argument and sets the attributes: • Type should be "Owl", nocturnal should be true and name is given as the argument ia printFeed method: • Should print "You give some mice." Overriding roam method: • Should print " flies around." Subclass Monkey: • Similar constructor: • Type should be "Monkey", nocturnal should be false and name is given as the argument printFeed method: Should print "You give some bananas."

Instructions The files provided in the code editor to the right contain syntax and/or logic errors. In each case, determine and fix the problem, remove all syntax and coding errors, and run the program to ensure it works properly. An example of the program is shown below: Enter a radius for a circle >> 7 The radius is 7 The diameter is 14 The area is 153.93791 Task 1: The DebugPen class compiles without error. This task is dependent on completing task #2. Task 2: The DebugCircle class methods work without errors. Task 3: The DebugFour1 class compiles without error. Task 4: The DebugFour1 program accepts user input and displays the correct output.
Rainfall Type Create a RainFall class that keeps the total rainfall in an array of doubles for each of the 12 months. Methods in the programme should return the following values: • the total annual rainfall; • the average monthly rainfall • the wettest month of the year • the month with the least amount of rain Demonstrate the class in its entirety. Validation of Input: Accepting negative amounts for monthly rainfall data is not permitted.
PROGRAMMING LANGUAGE: C++ ALSO PUT SCREENSHOTS WITH EVERY TASK. TASK 1 : A class of ten students took a quiz .The grades (integers are in range 0-100) for this quiz are available to you .Determine class average on quiz . TASK 2: Write c++ code that print summery of exam result and decide either student should have makeup class or not .If more then 30% of class fails in exam it’s mean they need a makeup class otherwise they don’t need any makeup class. For class strength take input from user (Hint: take two variables pass and fail) TASK 3: write a c++ that will determine whether a department-store customer has exceeded the credit limit on the charge account .For each customer , following facts are available : Account number (an integer) Balance at beginning of month Total of all items charged by this customer this month Total of all credit applied to this customer’s account this month. Allowed credit limit You are required to use a while structure to input each of these facts ,…
Exercise 6 - Loaded Coin Simulation Make a new class in the Lab2 project called LoadedCoinSim that simulates the toss of a loaded coin. A coin is loaded when it is constructed such that it is more likely to land on one value than another. Assume the probability the coin will land head is HEAD_PROB, and declare that as a constant in your program. Initially, use a value of 0.75, which means 75% chance the coin will show heads. Given this probability, simulate ten coin tosses and displaying the result. At the end, display the number of times the coin showed heads. The output should appear like this: Toss 1: HEADS Toss 2: HEADS Toss 3: HEADS Toss 4: TAILS Toss 5: HEADS Toss 6: HEADS Toss 7: HEADS Toss 8: HEADS Toss 9: TAILS Toss 10: HEADS Number of heads = 8
Eclipise Exercise 1: Write a Java application that simulates a test. The test contains at least five questions about first three lectures of this course. Each question should be a multiple-choice question with 4 options. Design a Test class. Use programmer-defined methods to implement your solution. For example: create a method to simulate the questions – simulateQuestion create a method to check the answer – checkAnswer create a method to display a random message for the user – generateMessage create a method to interact with the user - inputAnswer Display the questions using methods of JOptionPane class. Use a loop to show all the questions. For each question: If the user finds the right answer, display a random congratulatory message (“Excellent!”,”Good!”,”Keep up the good work!”, or “Nice work!”). If the user responds incorrectly, display an appropriate message and the correct answer (“No. Please try again”, “Wrong. Try once more”, “Don't give up!”, “No. Keep…
Using the dialog boxes in the JOptionPane class, write a program that calculates and prints themonthly paycheck for an employee. Use the class name “LastnameClasscodeFinal1”. The netpay is calculated after taking the following deductions:a) Federal Income Tax: 15%b) State Tax: 3.5%c) Social Security Tax: 5.75%d) Medicare/Medicaid Tax: 2.75%e) Pension Plan” 5%f) Health Insurance: $ 75.00Your program should prompt the user to input the gross amount and the employee name. Formatthe output to have two decimal places. A sample output follows: Juan Dela CruzGross Amount: $ 3575.00Federal Tax: $ 536.25State Tax: $ 125.13Social Security Tax: $ 205.56Medicare/Medicaid Tax: $ 98.31Pension Plan: $ 178.75Health Insurance: $ 75.00Net Pay: $ 2356.00
Please submit a flowchart of your program for your project below. Need a class which will contain: Student Name Student Id Student Grades (an array of 3 grades) A constructor that clears the student data (use -1 for unset grades) Get functions for items a, b, and c, average, and letter grade Set functions for items a, n, and c Note that the get and set functions for Student grades need an argument for the grade index. Need another class which will contain: An Array of Students (1 above) A count of number of students in use You need to create a menu interface that allows you to: Add new students Enter test grades Display all the students with their names, ids, test grades, average, and letter grade Exit the program Add comments and use proper indentation. Nice Features: I would like that system to accept a student with no grades, then later add one or more grades, and when all grades are entered, calculate the final average or grade. I would like the system to display the…
