RingBuffer.java Your first task is to create a data type to model the ring buffer. Write a class named RingBuffer that implements the following API: public class RingBuffer // Creates an empty ring buffer with the specified capacity. public RingBuffer(int capacity) // Returns the capacity of this ring buffer. public int capacity() // Returns the number of items currently in this ring buffer. public int size() // Is this ring buffer empty (size equals zero)? public boolean isEmpty() // Is this ring buffer full (size equals capacity)? public boolean isFull() // Adds item x to the end of this ring buffer. public void enqueue(double x) // Deletes and returns the item at the front of this ring buffer. public double dequeue() // Returns the item at the front of this ring buffer. public double peek() // Tests this class by directly calling all instance method. public static void main(String[] args)

### Exercise: Implement the sock drawer class using ADs class ADSockDrawer(object): def init_(self ): self.drawer = AD() def add_sock(self, color): """Adds a sock of the given color to the drawer. Do it in one line of code.""" # YOUR CODE HERE self.drawer.update(color) def get_pair(self, color): """Returns False if there is no pair of the given color, and True if there is. In the latter case, it removes the pair from the drawer. Do it in 5 lines of code or less.""" # YOUR CODE HERE @property def available_colors(self): """Lists the colors for which we have at least two socks available. Do it in 1 line of code.""" # YOUR CODE HERE

Build two classes (Fraction and FractionCounter) and a Driver for use in counting the number of unique fractions read from a text file. We’ll also reuse the ObjectList class we built in lab to store our list of unique FractionCounters, instead of directly using arrays or the ArrayList. Remember NO DECIMALS! Handle input of any length Introduction Your project is to read in a series of fractions from a text file, which will have each line formatted as follows: “A/B”. A sample text file is listed below, and the purpose of your program is to read in one line at a time and build a Fraction object from A and B. For each unique Fraction seen, your program will create a FractionCounter object used to track the number of occurrences of that specific fraction. When all the input is consumed, your program will print out its ObjectList of unique FractionCounters, which should report the fraction and its count – see output below. You can assume no blank lines or misleading characters; see…

Please Code in JAVA. Type the code out neatly. Add comments . (No need for long comments). Dont add any unnecesary code or comments. Do what the attached file says. And call it a day. Thanks !
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…
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.
Build two classes (Fraction and FractionCounter) and a Driver for use in counting the number of unique fractions read from a text file. We’ll also reuse the ObjectList class we built in lab to store our list of unique FractionCounters, instead of directly using arrays or the ArrayList. Rather than designing a monolithic chunk of code in main like we did in the previous homework, we’ll practice distributing our code into containers (called classes) that you will design specifically to tackle this same problem in a different and more logically organized fashion.
