( "Perimeter of first object="+rect1.getPerimeter()) I have a XML which is used to config some rules, it does not has complex structure, but this configuration is used anywhere in my system, so I want to parse this XML to java object and design as. When viewed at 100, each dot corresponds to an individual pixel on a display.

( "Area of first object="+rect1.getArea()) How to work with Bitmap in Android Android. Rectangle rect2= new Rectangle(15.0,8.0) create first object //and initialize with no arg constructor define a method to return perimeter double getPerimeter() define a method to return area double getArea() define two fields double length, width Call methods for these objects and show results. Create different objects initialized by constructors. Write a test class to use this Rectangle class. Java Area Of Rectangle : How to write Java Program to find Area Of Rectangle and Perimeter of Rectangle with example. Moreover add two methods to calculate and return area and perimeter of rectangle. * * Write a Java program to create a new class called 'Rectangle' with length and height fields and a no argument constructor and parameterized constructor. Test all the methods of the class for both the objects. It creates the first object with default values and the second object with user specified values. Write a test program that creates two rectangle objects. Note: Formula for area of rectangle is (width x height)įormula for perimeter of rectangle is: 2 x (width+height)Ī method getPerimeter() that will return the perimeter of the rectangle. A method getArea() that will return the area of the rectangle.A parameterized constructor that will create a rectangle with the specified x, y, height and width.A no-arg constructor that will create the default rectangle with width = 1 and height =1.Two member variables width and height ,.Define the Rectangle class that will have: Write a Java program using Objects and Classes concepts in Object Oriented Programming.Create a new Java Class Rectangle – This Python Tutorial will explain the creation of a new Java class named Rectangle with the following class specification: How To Create a New Rectangle Class in Java
