QUESTION 1 Which statement is TRUE about a pointer? O A pointer can be referred without initialisation or assignment. O The datatype of a pointer is determined by the datatype of the object the pointer is p O When a = &b; this means b is a pointer to a. O The datatype of a pointer can only be initialized to 0.0. QUESTION 2 When we introduce functions in our program, it is called approach prog O Modular O Object-oriented O Block O Linear QUESTION3 Which of the following matches the function call below? int a[4], b[4]; copy (a, b); O void copy(int], int]); O int copy (int[O, int[]) O void copy(int, int); O int copy(int); QUESTION 4 What is a pointer? O Avariable that directly references a value. 2 A collection of different of elements with the same types O A vaniable with fixed value O A collection of different type of elements

- Students make the Dean's list if their GPA is 3.5 or higher. Complete the Course class by implementing the getDeansList() method, which returns an ArrayList of students with a GPA of 3.5 or higher. Given classes: Class Course represents a course, which contains an ArrayList of Student objects as a course roster. (Type your code in here.) Class Student represents a classroom student, which has three fields: first name, last name, and GPA. (Hint: getGPA() returns a student's GPA.) Ex: If the following students and their GPA values are added to a course: Henry Nguyen with 3.5 GPABrenda Stern with 2.0 GPALynda Robison with 3.2 GPASonya King with 3.9 GPA then the getDeansList() method returns an ArrayList of 2 students and the program output is: Dean's list: Henry Nguyen (GPA: 3.5) Sonya King (GPA: 3.9) Course.java import java.util.ArrayList; public class Course { private ArrayList<Student> roster; // Collection of Student objects public Course() { roster = new…Q0p.

Provided are a PrimeMinister class and a Driver class. Prime Ministers have first and last names, and the year they were first elected. The natural sorting method for Prime Ministers is by their surnames ascending, then by their first names ascending, if the last names are the same. a. Create a class called BinarySearch. Within this class, create a method that will called binarySearch search an array for a given Prime Minister and return the index they were found at. Although, we are searching for PrimeMinisters, your class and method should be able to search any array of sortable objects. That is, your BinarySearch class should have no direct association with the PrimeMinister class. (You must program the recursive binary search algorithm yourself.

This program will contain an ArrayList of StudentGrades objects. The program will perform the following tasks: Create an instance of an ArrayList that will store three StudentGrades objects. Each element in the ArrayList represents student grades for a test (assessment). This means that each StudentGrades object stored by the ArrayList element represents the grades achieved by students for a single test. Prompt the user for the number of students in the class. The prompt text is: Enter the number of students in the course: [Keyboard Input] Add three new StudentGrades objects to the ArrayList. The StudentGrades objects should be populated with random values from 0 to 100. Use the enhanced for loop to print each of the StudentGrades objects to the console.
