4:12 ull ? AA A 1-xythos.content.blackboardcdn.com ITCS114 Assignment 2 Part (1) Create a class named Item, that includes two private members: Type (String), and Price(double). The Item class should also include: one set method, two get methods and default constructor to initialize Type to "None" and Price to 0.0. Part(2) Write another java program to do the following: a. Write a static method named findMax that takes as parameter an array of type Item. The method should find and output the Type of the item with the maximum price of all items in the array. The method prototype is: public static void findMax (Item [] list) b. Write the main method to do the following: Declare an array of type Item of size 5; 1. Ask the user to enter type and price for each item in the array 2. 3. Call the findMax method.
Question 3 The C program on the following page was written to provide a function calculate_primes which calculates and returns the first NUM_PRIMES prime numbers (in this case the first 10 prime num- bers). To test the function, the programmer has printed out the numbers returned by the function. However, the program does not work - there are TEN mistakes in the source code which prevent the program from working correctly. Find the ten mis- takes, and for each mistake identify the line number containing the mistake. Answers: Mistake 1 line number: Mistake 2 line number: Mistake 3 line number: Mistake 4 line number: Mistake 5 line number: Mistake 6 line number: Mistake 7 line number: Mistake 8 line number: Mistake 9 line number: Mistake 10 line number:

17. Create a class ShuffleCipher that implements the interface MessageEncoder, as described in Exercise 15. The constructor should have one parameter called n. Define the method encode so that the message is shuffled n times. To perform one shuffle, split the message in half and then take characters from each half alternately. For example, if the message is abcdefghi, the halves are abcde and fghi. The shuffled message is afbgchdie. (Hint: You may wish to define a private method that performs one shuffle.)
c++ A FastCritter moves twice as fast as a regular critter. When asked to move by n steps, it actually moves by 2 * n steps. Implement a FastCritter class derived from Critter whose move function behaves as described.

_4.1g Write a Java class that would match a string. The class has method match with String as a return type. It accepts two inputs: the phrase/sentence string (text) and the pattern string (word). This method finds the first (or all) instances of the pattern in the text and changes that word in all uppercase and return the new phrase. Method countOccurence accepts a phrase/sentence and a pattern string and returns its number of occurrences. Add a main method that will allow the user to input the phrase/sentence and pattern. Call method match and countOccurence. See test case below. Sample Input: Text string: You will always have my love, my love, for the love I love is as lovely as love itself. Pattern string: love . .

JAVA Program(*MUST WORK IN HYPERGRADE*) Homework #1. Chapter 7. PC# 2. Payroll Class (page 488-489) Write a Payroll class that uses the following arrays as fields: * employeeId. An array of seven integers to hold employee identification numbers. The array should be initialized with the following numbers: 5658845 4520125 7895122 8777541 8451277 1302850 7580489 * hours. An array of seven integers to hold the number of hours worked by each employee * payRate. An array of seven doubles to hold each employee’s hourly pay rate * wages. An array of seven doubles to hold each employee’s gross wages The class should relate the data in each array through the subscripts. For example, the number in element 0 of the hours array should be the number of hours worked by the employee whose identification number is stored in element 0 of the employeeId array. That same employee’s pay rate should be stored in element 0 of the payRate array. The class should have a method that accepts an…
