write in java Program a class representing a player hand. The hand should be unbounded in size. A hand should have some data structure containing cards. We should be able to add a card to the hand and remove a card from the hand. Cards should always be added to the end of the hand, but can be removed from any point in the hand. We should also be able to shuffle our hand, examine any card in our hand, count the cards in our hand, sort our hand by value (both from being completely unsorted and upon adding a card to or removing a card from a sorted hand), and search a sorted hand for cards of a specific value. You may implement any helper methods you need
So i need help understanding some stuff for my principles of programming class Can someone answer these using simple answers and examples? 1) What are primitive data types? what do they look like? 2) Are numerical data types a TYPE of primitive data type? yes or no? 3) What do associative arrays look like?

Hello, I am having trouble with this homework question for my c++ course. Implement a Rational Number class with the following specifications. Data members a) numerator and denominator Functions a) Constructors: 1) default constructor 2) single parameter constructor to create numerator/1 3) dual parameter constructor to create numerator/denominator 4) Use constructor delegation across all constructors. b) Accessors and Mutators for both data members. c) Static recursive GCD function using Euclid's algorithm. d) Static LCM function for two numbers. e) Reduce function simplify a rational number. This function modifies its calling object. f) Your program should work with the supplied driver program. Notes LCM (Least Common Multiple) This function returns the smallest multiple of a and b. Step 1: Multiply a and b to find a common multiple. Step 2: Divide the common multiple by the GCD of a and b. Step 3: Return the result of Step 2. Reduce: This function reduces a fraction to…
In Java: The program extends the representation for rational numbers Add a test class TestSimplifiedRational Define the simplified rationals r1..r4 and initialize them with 1/2, -3/9, 10/12 and 1 Compute sum=r1+r2 and diff=r4-r3 Simplify both results Check if they are equal, using equals and comparing their numerators and denominators. What do you observe? Compare r1 with r2, r3 and r4. Print all the rational numbers and partial results.
Reuse your Car class . In a main, build an object of that class, and print out the object using System.out.println(). Notice that this simply reports the memory address of the object in question, and we’d like to do something more useful. To replace (or override) the toString (or equals) function. Now, build a toString function that prints out the make, model, and odometer reading for a vehicle object. public class Car { //instance variables private int odometer; private String make; private String model; //overloading //constructors public Car(int odometer,String make, String model) { this.odometer = odometer; this.make = make; this.model = model; } public Car(String make, String model) { this.make = make; this.model = model; } public Car(String make) { this.make = make; } /* *getter & setter methods */ public int getOdometer() { return odometer; } public void…
T or F -Functions are considered to be objects in JavaScript because they contain three critical attributes: data, methods that act on the data, parameters for passing the data also known as awareness. -A recursive function is a function that calls itself and eventually returns default value to break out of the recursion. -A function that is used to create a new object is called an anonymous function. -Attributes define additional characteristics or properties of the element which is the same as for the start tag. -Javascript is similar to the Java programming language
identify the following as better representing static or dynamic binding. a) an int is an int forever and ever amen b) 2/2.0 = 1.0 c) 3/2.0 -> error message d) binding is done at compile time e) binding is slower but more flexible
Start with this class declaration: class Student { int sId; String name; double gpa;} Implement a Comparable and Comparator interface to provide the following three (3) alternative ways of ordering for the Student objects - based on sId (i.e., assume that this is selected as the natural ordering)- based on name, - based on gpa. Next declare a list of five Student objects, initialize them with random values. Test your code by printing out each of the following on separate lines: (original list of students, sorted list of students in ascending sId order, sorted list of students in ascending name order, sorted list of students in ascending gpa order).
Abstract data types In a paragraph, describe a real-world abstract data type that you can think of. Some of the examples we discussed in lecture were a mechanical throttle or a car's engine.
