Excercise: Listed next is the skeleton for a class named City. Each city has a name and temperature: public class City { private String cityName; private int temperature; } Flesh out the class with appropriate accessors, constructors, and mutators. Next, modify the class so that it implements the Comparable interface. The order between instances of the City class depends on the temperature. Test your class by creating an array of sample cities and sort them in an ascending order using Arrays.sort Notes: The language used for this question is Java. So far, this is the City class after fleshing it out: public class City implements Comparable<City> {private String cityName;private double temperature; public City() {} public City(String cityName, double temperature) {this.cityName = cityName;this.temperature = temperature;} public String getCityName() {return cityName;} public double getTemperature() {return temperature;} public void setName(String cityName)…

Through java, have The Delicious class – fields and constructor The class must define and initialise a field of an appropriate collection class to store Chicken objects. There must be no pre-defined limit on the number of Chiciken objects it can store.The Delicious class – basic methodsThe Delicious class must:• Define a method called addChicken that takes a Chicken object as a parameter and adds it to the ArrayList field. Note that this method must not create a Chicken object. Instead, a Chicken object must be passed into it as a parameter value.• Define a method called getNumberOfChickens that returns the number of Chicken objects in the ArrayList.• Define another method also called getNumberOfChickens. This one takes a single parameter of type int representing a price per Kilogram and returns the number of Chicken objects in the collection whose pricePerKilo is less than or equal to the value of the parameter.• Define a method called list that prints out, via System.out, the details…
10.5 LAB: Count probations (EO) Students are put on probation if their GPA is below 2.0. Complete the Course class by implementing the countProbation() method, which returns the number of students with a GPA below 2.0. 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: Refer to the Student class to explore the available methods that can be used for implementing the countProbation() method. Ex: If the following students and their GPA values are added to a course: Henry Cabot with 3.2 GPABrenda Stern with 1.2 GPALynda Robison with 3.3 GPAJake Flynn with 1.8 GPA then the countProbation() method returns 2 and the program output is: Probation count: 2 Course.java import java.util.ArrayList; public class Course { private ArrayList<Student> roster; // Collection of Student…
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 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 private 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 findHighestStudent() method returns a student and the program output is: Top student: Sonya King (GPA: 3.9)Code:Course.java: import java.util.ArrayList; //create class Student //create class Courseclass Courses{ private ArrayList<Student> roster; // collection of Student object // class constructor…
Part I Create a Student class that implements Comparable interface from java.lang.Comparable. Student should have name, lastName and studentId properties. Comparison should be done based on the alphabetical order of firstName and lastName. They should be compared on the lastName first, then the firstName Part II Write a main method and test your Student class by creating and sorting a Student array. You can use java.utils.Arrays an Arrays.sort to perform this operation. Note: Do not compress your files, submit only java files. Note: Do not forget to justify your answers with comments.
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…
Assume that a typical Reference Class called Student is accessible by the following method called linearSearch. Notice that the code for linearSearch is not complete. Assume further that the Student class has an attribute called lastName and that the class has a getter mehod called getLastName() .
