Array

The simplest way to start thinking about an array is as a collection, or a set of elements. In programming, these elements may be constants, variables, functions and pointers.

Consider the following statement, which is intended to create an ArrayList named
theater_club to store elements of type Student. Assume that the Student class has been
properly defined and includes a no-parameter constructor.
ArrayList<Student> theater_club = new /* missing code */;
Which choice can replace /* missing code */ so that the statement compiles without error?
(A) Student()
(C) ArrayList(Student)
(E) ArrayList<theater_club>()
5. Consider the following code segment.
System.out.println(nums);
(B) Student ArrayList()
(D) ArrayList<Student>()
ArrayList<Integer> nums = new ArrayList<Integer>();
nums.add(new Integer(37));
nums.add(new Integer(3));
nums.add(new Integer(0));
nums.add(1, new Integer(2));
nums.set(0, new Integer(1));
nums.remove(2);
What is printed as a result of executing the code segment?

In C# Use a one-dimensional array to solve the following problem. Write a class called ScoreFinder. This class receives a single dimensional integer array representing passer ratings for NFL players as an argument for its constructor. The test class will provides this argument. The test class then calls upon a method from the ScoreFinder class to start the process of finding a specific rating, which will be provided by the user. The method will iterate through the array and find any matching values. For all the matches that are found, the method will note the index of the cell along with its value. At completion, the method will print a list of all the indices and the associated scores along with a count of all the matching values.
