Exercise: 1) Design a class ComboLock that works like the combination lock in a gym locker, as shown below. The lock is constructed with a combination-three numbers between 0 and 39. The reset method resets the dial so that it points to 0. The turnLeft and turnRight methods turn the dial by a given number of ticks to the left or right. The getStatus method returns a Boolean indicating whether the lock is opened(true) or closed(false). The lock opens if the user first turned it right to the first number in the combination, then left to the second, and then right to the third. 36 2) Document your class. 3) Provide a tester class and test a scenario in which you create a comboLock having the code (25, 36, 19), unlock it successfully, and print the status of the lock after each turn. 4) Put the ComboLock class and the tester class in two distinct packages

Exercises: PolymorphismProblem 1. VehiclesWrite a program that models 2 vehicles (Car and Truck) and will be able to simulate driving and refueling them inthe summer. Car and truck both have fuel quantity, fuel consumption in liters per km and can be driven givendistance and refueled with given liters. But in the summer both vehicles use air conditioner and their fuelconsumption per km is increased by 0.9 liters for the car and with 1.6 liters for the truck. Also the truck has a tinyhole in his tank and when it gets refueled it gets only 95% of given fuel. The car has no problems when refueling andadds all given fuel to its tank. If vehicle cannot travel given distance its fuel does not change.Input On the first line - information about the car in format {Car {fuel quantity} {liters per km}} On the second line – info about the truck in format {Truck {fuel quantity} {liters per km}} On third line - number of commands N that will be given on the next N lines On the next N lines –…
Write complete java code for scenario given: Consider a Java class that you could use to get an acceptable integer value from the user. An object of this class will have the attributes: Minimum accepted value Maximum accepted value • Prompt String and the following method: getValue() displays the prompt and reads a value from the user. If the value read is not within the allowed range, the method should display an error message and ask the user for a new value, repeating these actions until an acceptable value is entered. The method then returns the value read.
Slide Type Slide • Exercise # 1: Define a class Point that represents a point in 2 – D plane. The point has x and y coordinates. Define the following: • A constructor to initialize the x, y coordinates. • A method translate(self, dx,dy) to translate the point object dx , and dy units in x and y directions, respectively. • A method distanceTo (self, point2) to return the distance between the point referenced by self and point2. • getX(self) to return the value of x coordinate. • getY(self) to return the value of y coordinate Test the above class by: • Creating 2 point objects; one with (3,5) as x,y coordinates; the second with (-10,30) as x,y coordinates. • Move the first point 5.5 units in x direction and -12.5 units in y direction using translate method • Find the distance between the 2 points in their current location using distance To method A Sample output resulting from running the above test class is shown below new coordinates of point1= (8.5 , -7.5) Coordinates of point 2 =…
2019 AP® COMPUTER SCIENCE A FREE-RESPONSE QUESTIONS 2. This question involves the implementation of a fitness tracking system that is represented by the StepTracker class. A StepTracker object is created with a parameter that defines the minimum number of steps that must be taken for a day to be considered active. The StepTracker class provides a constructor and the following methods. addDailySteps, which accumulates information about steps, in readings taken once per day activeDays, which returns the number of active days averageSteps, which returns the average number of steps per day, calculated by dividing the total number of steps taken by the number of days tracked The following table contains a sample code execution sequence and the corresponding results. Statements and Expressions Value Returned Comment (blank if no value) StepTracker tr StepTracker(10000); Days with at least 10,000 steps are considered active.

Ag 1- Random Prime Generator Add a new method to the Primes class called genRandPrime. It should take as input two int values: 1owerBound and upperBound. It should return a random prime number in between TowerBound (inclusive) and upperBound (exclusive) values. Test the functionality inside the main method. Implementation steps: a) Start by adding the method header. Remember to start with public static keywords, then the return type, method name, formal parameter list in parenthesis, and open brace. The return type will be int. We will have two formal parameters, so separate those by a comma. b) Now, add the method body code that generates a random prime number in the specified range. The simplest way to do this is to just keep trying different random numbers in the range, until we get one that is a prime. So, generate a random int using: int randNum = lowerBound + gen.nextInt(upperBound); Then enter put a while loop that will keep going while randNum is not a prime number - you can…

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
PYTHON: Define the Artist class with a constructor to initialize an artist's information and a print_info() method. The constructor should by default initialize the artist's name to "None" and the years of birth and death to 0. print_info() should display Artist Name, born XXXX if the year of death is -1 or Artist Name (XXXX-YYYY) otherwise. Define the Artwork class with a constructor to initialize an artwork's information and a print_info() method. The constructor should by default initialize the title to "None", the year created to 0, and the artist to use the Artist default constructor parameter values. Ex: If the input is: Pablo Picasso 1881 1973 Three Musicians 1921 the output is: Artist: Pablo Picasso (1881-1973) Title: Three Musicians, 1921 If the input is: Brice Marden 1938 -1 Distant Muses 2000 the output is: Artist: Brice Marden, born 1938 Title: Distant Muses, 2000 I have the code but I am getting errors that I can't seem to get rid of any suggestions would be appreciated
