In Java, please. Complete the Course class by implementing the findStudentHighestGpa() 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) LabProgram.java import java.util.Scanner; public class LabProgram { public static void main(String args[]) { Scanner scnr = new Scanner(System.in); Course course = new Course(); int…

For beginning Java, here is my assingment " 1. Define a Java class named “Appointment” that contains a day, a month and adescription of the appointment (string). It should provide at least a method named“hasTheSameDate” that will compare with another Appointment object andreturn true if it has the same date (day and month) and false otherwise. It shouldalso have the toString() method to return a string in the format of“mm/dd: description” such as “6/1: Meet with John”2. Write the main method to show how you can create Appointment objects, call thehasTheSameDate() method and print out the “Appointment” information: a. Ask the user for input for 2 appointment objects. b. Print the 2 objects. c. Call hasTheSameDate() to compare the 2 objects and tell the user if they are the same or different."Here is my code, and I don't know on what is wrong with my code: " import java.util.Scanner; class Appointment { private int day; private int month; private String…

Write a Java class called MostOftenOccurring. This class defines a method called occursMostOften(), which takes as its only parameter an array of int called a and returns an int representing the value which occurs most often in a. If there is a tie, display the value which occurs first in a among those that occur most often. Repeat the operation often.
ANSWER IN JAVA: 3.14 (Date Class) Create a class called Date that includes three instance variables-a month (type int), a day (type int) and a year (type int). Provide a constructor that initializes the three instance variables and assumes that the values provided are correct. Provide a set and a get method for each instance variable. Provide a method displayDate that displays the month, day and year separated by forward slashes (/). Add a main method to the class that demonstrates class Date's capabilities. STANDARD OUTPUT: Enter·the·month,·day·and·year·in·the·form·XX·XX·XXXX·and·hit·enter:The·Date·object's·state·is:·11/5/1929↵ Enter·a·new·year:The·Date·object's·state·is:·11/5/1978↵ Enter·a·new·day:The·Date·object's·state·is:·11/12/1978↵ Enter·a·new·month:The·Date·object's·state·is:·6/12/1978↵
