Q1. Write a java program to draw triangle 1 Like 2 2 3 4 3 3 4 4 4 ● Default constructor must set values for rows and columns 4. Parametrized constructor will take value upon object creation. First draw() method will print the triangle for number of rows and columns set during object creation. Second draw() will print the triangle having rows and columns passed as parameters. Note: Please make sure rows value must be equal to columns before drawing rectangle. otherwise print "No Triangle". -rows: int Triangle -columns: int +Triangle() +Triangle(rows:int, columns:int) +draw():void +draw(rows:int, columns:int):void

Shape Class JAVA Implement the Shapehierarchy shown in figure below. Shape TwoDimensionalShape ThreeDimensionalShape Circle Square Sphere Cube Each TwoDimensionalShape should contain method getArea to calculate thearea of the two-dimensional shape. • Each ThreeDimensionalShape should have methods getArea and getVolume tocalculate the surface area and volume, respectively, of the three- dimensional shape. Add OneDimensionalShape with sub classes , and add more shapes to classes (TwoDimensionalShape , ThreeDimensionalShape ). Create a program that uses an array of Shape references to objects of each concrete class in the hierarchy. The program should print a text description of the object to which each array element refers. • Also, in the loop that processes all the shapes in the array, determine OneDimensionalShape, whether each shape is a TwoDimensionalShape or a ThreeDimensionalShape. If it is a TwoDimensionalShape, it is display ThreeDimensionalShape, display its area and volume. its…

Hello all! Need some help with this assignment. Need to create an array of 8 employees ( see image for details ) Thank you!

An object of the class Timer is used to indicate when a certain amount of time (in seconds) has elapsed, after which it provides a “DING". The required data field is remainingTime which is the number of seconds until the “DING". When a Timer object is constructed, it is set with the desired number of seconds. When the timer "ticks", it is one second closer to the "DING". This is represented with the tick) method. The dingChecko method indicates whether the timer should be "DINGING". Provide the code for the constructor method, and the methods getRemainingTime), tick(), and dingCheck). public class Timer // Methods // Data private int KeuainingTinei }

Find the maximum clock frequency at which the counter in figure, can be operated. Assume that the propagation delay through each flip-flop and AND gate is 10 ns. Also assume that the setup time for the JK inputs of the flip-flops is negligible. Qo J1 Q1 Q2 K, CLK K, CLK K, CLK Clock

In main.py define the Student class that has two attributes: name and gpa Implement the following instance methods: • A constructor that sets name to "Louie" and gpa to 1.0 set_name(self, name) - set student's name to parameter name get_name(self) - return student's name set_gpa(self, gpa) - set student's gpa to parameter gpa get_gpa(self) - return student's gpa Ex. If a new Student object is created, the default output is: Louie/1.0 Ex. If the student's name is set to "Felix" and the gpa is set to 3.7, the output becomes: Felix/3.7

The Factory method design pattern is useful since it can be used to create new objects of a particular type dynamically. True False

Create a Point class to hold x and y values for a point. Create methods show(), add() and subtract() to display the Point x and y values, and add and subtract point coordinates. Create another class Shape, which will form the basis of a set of shapes. The Shape class will contain default functions to calculate area and circumference of the shape, and provide the coordinates (Points) of a rectangle that encloses the shape (a bounding box). These will be overloaded by the derived classes; therefore, the default methods for Shape will only print a simple message to standard output. Create a display() function for Shape, which will display the name of the class and all stored information about the class (including area, circumference and bounding box). Build the hierarchy by creating the Shape classes Circle, Rectangle and Triangle. Search the Internet for the rules governing these shapes, if necessary. For these three Shape classes, create default constructors, as well as constructors…

In Java Write a Fraction class that implements these methods:• add ─ This method receives a Fraction parameter and adds the parameter fraction to thecalling object fraction.• multiply ─ This method receives a Fraction parameter and multiplies the parameterfraction by the calling object fraction.• print ─ This method prints the fraction using fraction notation (1/4, 21/14, etc.)• printAsDouble ─ This method prints the fraction as a double (0.25, 1.5, etc.)• Separate accessor methods for each instance variable (numerator , denominator ) in theFraction classProvide a driver class (FractionDemo) that demonstrates this Fraction class. The driver class shouldcontain this main method : public static void main(String[] args) { Scanner stdIn = new Scanner(System.in); Fraction c, d, x; // Fraction objects System.out.println("Enter numerator; then denominator."); c = new Fraction(stdIn.nextInt(), stdIn.nextInt()); c.print(); System.out.println("Enter numerator; then denominator."); d = new…
