Create a RightTriangle class given the following design: RightTriangle variables: base, height methods: 2 constructors, 1 that set default values and another that accepts to parameters. setBase - changes the base. Requires one parameter for base. setHeight - changes the height. Requires one parameter for height. getBase - returns the triangle base. getHeight - returns the triangle height. area - returns the area of the triangle (1/2bh) given the current base and height

class Airplane – highlights -- planeID : String -planeModel: String //"Boeing 757" etc. --seatCapacity : int //would vary by outfitting ............ Assume getters and setters, toString(), constructor with parameters and constructor .................. Write lambdas using a standard functional interface to: a) Given a plane object and a required number of seats as an input, determine if the given plane meets or exceeds the required capacity b) Output the plane description if capacity is less than 80% of a specified number (We would use his for planning aircraft assigned to various routes. ) c) Adjust the seats in a plane by a specified positive or negative number [after modifications have been made to the interior.] ...and write an example for each showing the usage, using an Airplane instance plane1

1. Dummy GUI Application by Codechum Admin A GUI Application is an application that has a user interface that the user can interact with. For this program, we will be simulating this behavior. First, implement another class called Checkbox which implements the Clickable interface which has only one method: public void click(). The Checkbox will have the following properties: private boolean isChecked (defaults to false upon the creation of object) private String text Additionally, it should have the following methods: the implementation of the click() method If the isChecked is currently false, this will set the isChecked to true and will then print the message "Checkbox is checked". If it is currently true, this will set the isChecked to false and will then print the message "Checkbox is unchecked". Note that the messages to be printed should have also print a new line at the end. an override of the toString() method which returns the message: "Checkbox ({text} - Clicked...

mau Open Leathing inta... - The class has data members that can hold the name of your cube, length of one of the sides and the color of your cube. - The class has a constructor that accepts the name, length of one of the sides, and color as arguments and sets the data members to those values. - The class has the following methods to set the corresponding data member. setName(string newName) setSide(double newSide) setColor(string newColor) - The class has a method called getVolume() that returns the volume of the cube, calculated by cubing the length of the side. - The class has a method called volumelncrease(double newVolume) that receive the percent the volume should increase, and then the side to the corresponding value. i - For example, 2.5 indicates 2.5% increasing of the volume. So you take the current volume, increase it by 2.5%, and then find the cube root to calculate the new side length. You can use the built in function called cbrt, part of the math library, to find the cube...

A class object can encapsulate more than one [answer].

In C#, a program that implements and uses a class called MyRectangle. Data items should include: length, width, color, and label. Define properties with appropriate accessor functions for each of the data items. Methods should include a default constructor that sets values to the empty string or zero, a constructor that allows the user to specify all values for the data items, a member method that computes and returns the area of the shape, and a member method called DisplayShape that outputs all the information (including the area via the ComputeArea method for the given rectangle in a reasonable format. Sample output below

public class Artwork { // TODO: Declare private fields - title, yearCreated // TODO: Declare private field artist of type Artist // TODO: Define default constructor // TODO: Define get methods: getTitle(), getYearCreated() // TODO: Define second constructor to initialize // private fields (title, yearCreated, artist) // TODO: Define printInfo() method // Call the printInfo() method in Artist.java to print an artist's information }} public class ArtworkLabel { public static void main(String[] args) { Scanner scnr = new Scanner(System.in); String userTitle, userArtistName; int yearCreated, userBirthYear, userDeathYear; userArtistName = scnr.nextLine(); userBirthYear = scnr.nextInt(); scnr.nextLine(); userDeathYear = scnr.nextInt(); scnr.nextLine(); userTitle = scnr.nextLine(); yearCreated =...

Java A class always has a constructor that does not take any parameters even if there are other constructors in the class that take parameters. Choose one of the options:TrueFalse

public class Plant { protected String plantName; protected String plantCost; public void setPlantName(String userPlantName) { plantName = userPlantName; } public String getPlantName() { return plantName; } public void setPlantCost(String userPlantCost) { plantCost = userPlantCost; } public String getPlantCost() { return plantCost; } public void printInfo() { System.out.println(" Plant name: " + plantName); System.out.println(" Cost: " + plantCost); }} public class Flower extends Plant { private boolean isAnnual; private String colorOfFlowers; public void setPlantType(boolean userIsAnnual) { isAnnual = userIsAnnual; } public boolean getPlantType(){ return isAnnual; } public void setColorOfFlowers(String userColorOfFlowers) { colorOfFlowers = userColorOfFlowers; } public String getColorOfFlowers(){ return colorOfFlowers; } @Override public void printInfo(){...
