Write a program that reads numbers from an array and graphs the information in the form of a bar chart or histogram. If the number is printed, then a bar consisting of that many asterisks is printed beside the number. Note: The defined size of the array is 10. See the example below.
6. Write a program to determine the maximum height to which a projectile will travel if atmospheric resistance is neglected, for different initial velocities. This problem demonstrates the use of repetition controlled by a terminating limit.
Method:
The mass of the projectile is m, the initial velocity is v0 m/sec, and the last initial velocity is vfft/sec. From equations of motion: w=mg, Fz=maz. Applying these equations for the projectile results in the following equations: mg=mac gives ac = g.
Initial conditions:
s0 = 0, v0 = v.
Final conditions:
sf = h, vf = 0.
From Kinematics:
vf2 = v02 + 2ac(s – s0).
0 = v2 + 2ac(h – h0).
2ach = v2.
h = 2acv2.
Data:
Real values of initial velocity at 50, 100, 150, and 200 ft/sec.
The real value of gravitational acceleration is 32.2 ft/sec2.
![Large Integers Part #1 Largelnteger Class An array can be used to store large integers, one digit at a time. For example, the integer 1234 could be stored in the array num by setting num[0] to 1, num[1] to 2, num[2] to 3, num[3] to 4. However, for this class implementation, you might find it more useful to store the digits backward; that is, place 4 in num[0], 3 in num[1], 2 in num[2], and 1 in num[3]. For the sake of simplicity, we will be storing and manipulating only with positive large integers. Implement a class named Largelnteger that stores a large integer as an array of its digits. Class must extend HasState class (provided). This is needed to make sure clone() method is written correctly. Class must have the following: - Fields - Constant arraySize must be set to 23 - Partially filled array of integers of length 23 - int digitCount keeps the number of digits in large integer, e.t. how many elements of the partially filled array are used to store the number - No-argument constructor that stores number 0 in the array. Sets digitCount to 1 - Constructor that takes a string as a parameter. The constructor parses the given string and converts it into Large Integer by storing digits in the partially filled array. - Create a new custom Exception class called LargelntegerNumberFormatException. The constructor throws exceptions of this type when - string is too long to be stored as a 23-digit number or - when string is empty or - when the string contains non-digits and thus cannot be converted into a number. - Constructor that takes a number of type long as a parameter and builds an object from it by storing digits in an array. - This constructor also throws a custom LargelntegerNumberFormatException when a parameter passed to the constructor is a negative number. - getDigitCount() accessor to the digit count variable. - toString() method that converts an array into a string of numbers in the correct order. Number 12345 is converted into a string "12345" - add(Largelnteger) method that returns the sum of this integer and the one passed as a parameter. The method adds two large integers by implementing the usual "paper and pencil" addition algorithm. This is when the backward storage arrangement of those numbers in arrays will pay off. Carry-over will be easier to do when the integer is stored backward. - Create another custom Exception class called LargelntegerOverflowException. If the resulting number is more than 23 digits long, the add() method throws a LargelntegerOverflowException type exception. - Implement clone() method. - Make your class implement Relatable interface. Code of the interface is provided. Implement all three methods of the Relatable interface. Part #2 Polymorphic Class This class exists only to house one static method called isSorted(). The method must take an array of objects of type Relatable and check if the array is sorted with the help of methods of Relatable interface. The method returns true if the array is sorted and false if it is not. The whole purpose of this exercise is to illustrate the concept of polymorphism. The purpose of this class is to house three static methods. 1. Method void writeLargelntegerArray(Largelnteger[], String) takes an array of Large Integers and a name of a file as parameters. The method writes the contents of the given array into the given binary file (in binary mode). The method throws IOExceptions. The IOExceptions may originate in the methods but must not be handled. Instead, they must be propagated to the calling code. - Make sure to add implements Serializable to the Largelnteger class header. Binary IO will fail to work without that. 2. Method Largelnteger[] readLargelntegerArray(String) method reads the contents of a binary file with the given name as an array of objects of type Largelnteger. Assume you do not know the amount of data in the file. Read data one Largelnteger object at a time and store the objects in ArrayList first. After the end of the file has been reached, convert the ArrayList into a regular array of objects that can be returned from the method. - Please study EOFDemo.java code example to learn how to use exceptions when checking for the end of the file while reading from a binary file. - This method also throws IOExceptions. The IOExceptions may originate in the methods but must not be handled. Instead, they must be propagated to the calling code. 3. Method Largelnteger addLargelntegersFromFile(String) takes a text file name as a parameter. It reads an arbitrary number of strings of text from the file, converting them into Largelntegers as it reads. The Large Integers are added one by one to the running total with the help of add() method. The sum of all the Large Integers stored in the file as strings is then returned from the method. - The structure of the file may be imperfect. Some strings may contain corrupted data and will fail to be converted into Largelnteger. This must not interrupt the process of reading from the file. The corrupted string must be skipped over, and the next string must be read and converted. Use a try/catch block to catch and ignore LargelntegerNumberFormatException. - The sum of all numbers stored in the file may become too big to be stored in a Large Integer. In that case, a LargeIntegerOverflowException exception will be thrown by the add() method. If this happens, catch the exception and return a null value from the method. - This method also throws IOExceptions. The IOExceptions may originate in the methods but must not be handled. Instead, they must be propagated to the calling code.](https://gotit-pro.com/wp-content/uploads/2023/10/a2443259-5cf9-45ff-9909-fdcfa036711f.png)
![Question 1: Feeding your pet dog [7 Marks] Dogs eat food, which creates energy that they use to go about their lives. But how much food should you feed your dog? Your job is to write a simple program that helps people decide how much to feed their dog per day. Note: Creating more than one Scanner on System.in in the same program will cause problems. Create ONE Scanner in main, and pass it to any methods that need it. a) Weight How much you should feed your dog depends on how much it weighs. For every pound of the dog, they should have a quarter cup of food. Write a method called convertKGtoLB that accepts one double parameter - a weight in kilograms (kg). The method should calculate and return a double value - the same weight converted to pounds (lb). Write a method called readWeight that receives a Scanner as a parameter. Using the Scanner, the method should read in a dog's weight from the user and return it as a double. Ask the user if they want to enter a weight in kilograms or pounds - prompt the user to enter the letters 'k' for kilograms or 'p' for pounds. Then read in the user's response using the Scanner. If the user enters something other than 'k' or 'p', assume that they want to use pounds and print a reasonable message telling them so. Then prompt the user to enter the dog's weight in the chosen units and read it in as a double. This method should return the weight in pounds. If they entered the weight as kilograms, convert it to pounds by using the convertKGtoLB method. Puppies need more food to grow big and strong. Puppies should eat a half cup of food per pound they weigh. Write a method called readIsPuppy that receives a Scanner as a parameter. Using the Scanner, the method should read in if the dog is a puppy (a baby dog). Ask the user if the dog is a puppy - prompt the user to enter the letters 'y' for yes or 'n' for no. Then read in the user's response using Scanner. If the user enters something other than 'y' or 'n', assume that it is not a puppy and print a reasonable message telling them so. This method should return a boolean. Return true if the dog is a puppy, or false if not a puppy. c) Activity Level More active dogs will need more food. For every four miles walked a day, a dog should get a quarter cup more food. Write a method called convertKMtoMI that accepts one double parameter - a distance in kilometers (km). The method should calculate and return a double value - the same distance converted to miles (mi). Write a method called readActivityLevel that receives a Scanner as a parameter. Using the Scanner, the method should read in a dog's daily walking distance and return it as a double. Ask the user if they want to enter a distance in kilometers or miles - prompt the user to enter the letters 'k' for kilometers or 'm' for miles. Then read in the user's response using the Scanner. If the user enters something other than 'k' or 'm', assume that they want to use miles and print a reasonable message telling them so. Then prompt the user to enter the dog's daily walking distance in the chosen units and read it in as a double. This method should return the distance in miles. If they entered the distance as kilometers, convert it to miles by using the convertKMtoMI method. d) Breed Some dog breeds have special requirements. Labradors and Golden Retrievers should get a quarter cup more food per 5 pounds they weigh. German Shepherds should get a quarter cup more food per seven pounds they weigh. Bernese Mountain Dogs should get a quarter cup less food per ten pounds they weigh. Other breeds do not have special considerations. Write a method called readDogBreed that receives a Scanner as a parameter. Using the Scanner, the method should read in a dog's breed and return it as a char. Prompt the user to enter a letter to represent their dog breed as follows: 'l' for Labrador, 'r' for Golden Retriever, 'g' for German Shepherd, 'b' for Bernese Mountain Dog, or 'o' for other. Then read in the user's response using Scanner. If the user enters something other than 'l', 'r', 'g', 'b' or 'o', assume that their dog is other and print a reasonable message telling them so. This method should return the letter of the dog breed. e) Calculate the Amount Write a method called findFoodAmount that accepts several parameters - a weight in pounds (lb), whether the dog is a puppy, the dog's daily walking distance (mi), and the dog's breed. The method should compute and return the amount of food to feed the dog. In addition to the amounts stated above, the following must also be considered: - Overweight dogs should get one cup less. An overweight Labrador, Golden Retriever, or German Shepherd is over 80 lbs. An overweight Bernese Mountain Dog is over 90 lbs. There is no limit known for other breeds of dogs. - Puppies should also get one cup less, but overweight puppies (over 80/90 pounds, as above) should not have a reduction in their food. f) Print the amount Write a method called printFoodAmount that accepts the amount of food to feed the dog. The method should print a nice message telling the user how much food to feed their dog. Question 2: Farkle Scoring [8 Marks] Farkle is a dice game where you roll six dice and try to be the first to score 10,000 points or more. Your job is to create a Farkle scoring program. Given one to six dice, you will determine the score for those dice. Farkle Rules: - Each person rolls six dice and sees if they have rolled any scoring dice or combinations. Any dice that score may be set aside. You must set aside at least one scoring dice of your choice, if possible, but it is not required to set aside all scoring dice. Then you may choose to roll the remaining dice. - For example, if you rolled 1-3-3-5-5-6, you could set aside the 1 and the two 5's for scoring, or you could choose to set aside only the 1. All dice that are not set aside may be rerolled. - If all six dice are set aside for scoring, you can roll all six dice again and continue adding to your accumulated score. Or you can bank your points, end your turn, and pass the dice to the next player. - Your turn continues until either you decide to stop and score your points, or until you fail to roll any scoring dice on a throw (known as a Farkle) and all your points gained so far on that turn are lost. - At the end of your turn, any points you have scored are written down and the dice are passed to the next player. Reminder 1: Your job is to create a Farkle scoring program. Given 1 to 6 dice in ascending order, you will determine the score for those dice. You are not implementing a complete game. Reminder 2: This assignment should be completed using material from Weeks 1-6. (No loops needed!) c) Print the score Write a method called printScore that accepts the score. The method should print a nice message telling the user how much they scored. If the user scored zero points, the program should print "Farkle!". Example Outputs: Dice to Score: 123456 Points Earned: 3000 Dice to Score: 123555 Points Earned: 600 Dice to Score: 223346 Farkle!](https://gotit-pro.com/wp-content/uploads/2023/10/7692d785-5bf0-40dc-bafd-7ce93b1e4999-300x259.png)
