- java Write an interface for Animal. We will say that every Animal will make a sound and will also be able to give its type.arrow_forwardJava. Please use the template in the picture.arrow_forwardIn 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…arrow_forward
- Implement the following in the .NET Console App. Write the Bus class. A Bus has a length, a color, and a number of wheels. a. Implement data fields using auto-implemented Properies b. Include 3 constructors: default, the one that receives the Bus length, color and a number of wheels as input (utilize the Properties) and the Constructor that takes the Bus number (an integer) as input.arrow_forwardThe usual definition of a palindrome is a word that reads the same both forward and backward, like “otto” and “palindromeemordnilap.” An alternative way to define a property like this is to specify a way of testing for the property. For example, we might say, “a single letter is a palindrome, and a two-letter word is a palindrome if the letters are the same, and any other word is a palindrome if the first letter is the same as the last and the middle is a palindrome.” Write a recursive method named isPalindrome that takes a String and that returns a boolean indicating whether the word is a palindrome or not.arrow_forwardThere are three main operations on rectangles: intersection, union, and difference. Among them, only intersection is guaranteed to return another rectangle. In general, the union of two rectangles is... two rectangles, and the difference between two rectangles is ... a whole lot of rectangles, as we will see. We let you implement rectangle intersection. Of course, the intersection is defined only if the rectangles have the same number of dimensions. The intersection is computed by taking the intersection of the intervals of the two rectangles for corresponding dimensions. If one of the intervals is empty, you should return None. [] # @ title Rectangle intersection def rectangle_and(self, other): if self.ndims != other.ndims: raise TypeError("The rectangles have different dimensions: {} and {}".format( )) self.ndims, other.ndims ### YOUR SOLUTION HERE Rectangle. _and_ = rectangle_and [ ] r1 = Rectangle((2, 3), (0, 4)) r2 = Rectangle((0, 4), (1, 3)) draw rectangles (r1, r2) draw…arrow_forward
