7.4 LAB: Find student with highest GPA Complete the Course class by implementing the find Student HighestGpa() method, which returns the Student object with the highest GPA in the course. Assume that no two students have the same highest GPA. Given classes: • Class LabProgram contains the main method for testing the program. • 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.) Note: For testing purposes, different student values will be used. Ex. For the following students: Henry Nguyen 3.5 Brenda Stern 2.0 Lynda Robison 3.2 Sonya King 3.9- the output is: Top student: Sonya King (GPA: 3.9)

Matrix Multiplication Write a method called multiply in the Matrix class that takes an instance of Matrix as a parameter and returns the result of matrix multiplication. Complete the definition of the class Matrix and method definition multiply shown here and in the starter code. public class Matrix { public Matrix multiply(Matrix other) { // fill in code here } } For purposes of this exercise, you should assume (without checking) that the matrices to be multiplied have the correct shapes, ie, that this.numCols() is equivalent to other.numRows(). To multiply matrices, the number of columns in the first matrix must equal the number of rows in the second matrix. In general, if we multiply an m x n matrix A (ie, having m rows and n columns) by a n x p matrix B (ie, having n rows and p columns), the product will have size m x p (ie, m rows and p columns). Here is a simple illustration of the computation for two 2 x 2 matrices:     Examples Example 1 If A and B were both instances of the…

Add the function min as an abstract function to the class arrayListType to return the smallest element of the list. Also, write the definition of the function min in the class unorderedArrayListType and write a program to test this function. I have 5 tabs: I have tried every solution I can think of with no luck. These are the guides: arrayListType.h arrayListTypeImp.cpp: main.cpp unorderedArraryListType.h unorderedArrayListTypeImp.cpp I am needing these in order to pass the assignment in Cengage Mindtap, please help with codes for each one if possible.

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.)
