JAVA Which is true about arrays and methods? A. Arrays cannot be passed to methods B. Passing an array to a method creates a copy of the array within the method C. An array is passed to a method as a reference D. A programmer must make a copy of an array before passing the array to a method

6. Design a Java class with a main method that does the following. You must include a meaningful comment for main and each method a. Main invokes a method readScores to read input from a file (name of your choice) that contains the name of the bowlers (no more than 25) and their bowling scores (two scores per bowler). The program stops reading values when it has reached the end of the file. For example, the file might contain: Bob 203 176 Jane 210 253 Jack 300 189 Eileen 220 298 • As the method reads the data, it stores the name into a String array and the average of the two bowling scores into an array of double. • The method returns the actual number of bowlers read in b. Main then invokes a method computeOverallAvg to: compute (a) the overall average score of all the bowlers combined, (b) the average score and name of the bowler with the highest average score and (c) the average score and name of the bowler with the lowest average scores. print to the console (a) the overall average…

Write a C# program that uses a class called ClassRegistration as outlined below: The ClassRegistration class is responsible for keeping track of the student id numbers for students that register for a particular class. Each class has a maximum number of students that it can accommodate.   Responsibilities of the ClassRegistration class: It is responsible for storing the student id numbers for a particular class (in an array of integers) It is responsible for adding new student id numbers to this list (returns boolean) It is responsible for checking if a student id is in the list (returns a boolean) It is responsible for getting a list of all students in the class (returns a string). It is responsible for returning the number of students registered for the class (returns an integer) It is responsible for returning the maximum number of students the class is allowed (returns an integer) It is responsible for returning the name of the class. (returns a string)

Write a program in Java that handles the order list for an online retailer. Your program should contain a minimum of three classes: Order Class Display Class Main Class Create a Order Class that uses a queue to hold the orders in the order they were taken. The queue should contain the customer last name, order number, and order total cost. Create a Display Class that will store a copy of the order queue in two arrays. Each array will contain the order list but one will be sorted by name and the other sorted by order number. When a order is taken and stored in the Order Class the program will update theDisplay Class arrays automatically sort them in descending order using quick sort and outputs the the contents to the console upon each entry of new data. Create a Main Class that will handle operator data input and when an order is added or removed, the program will update the Order Class and Display Class. The user will be presented a menu to add a order, remove a order and display…
