First of all, we need to have our Rectangle class. public class Rectangle { } There! We've defined a Rectangle class, for making Rectangle objects. Now, it needs some properties. We'll say these are integer numbers, called x, y, width, and height. Our class now looks like this:

Sep 7, 2021 · With this tutorial, you will learn how to create a class in Java and how to access its methods and parameters. We will follow the following steps: Create one Rectangle class. This class will take the height and width of the rectangle in its constructor.

A Rectangle specifies an area in a coordinate space that is enclosed by the Rectangle object's upper-left point (x,y) in the coordinate space, its width, and its height. A Rectangle object's width and height are public fields.

Rectangle(int x1,int y1,int x2,int y2) { x1 = p1.x; y1 = p1.y; x2 = p2.x; y2 = p2.y; } your variables p1 and p2 haven't been initialized to anything, since before that, all you do is declare those two fields, not actually set them to anything.

Jul 23, 2022 · The main task here is to create a class that can be used to find the Area and Perimeter of a rectangle. By using the formula for Area of Rectangle and Perimeter of Rectangle: Area of Rectangle = Length * Breadth

if you want to use rectangle object you could do it like this: import java.applet.Applet; import java.awt.*; public class Rect1 extends Applet { public void paint (Graphics g) { Rectangle r = new Rectangle(arg,arg1,arg2,arg3); g.fillRect(r.getX(), r.getY(), r.getWidth(), r.getHeight()); g.setColor(color); } }

Jul 10, 2019 · How To Create a New Rectangle Class in Java. Write a Java program using Objects and Classes concepts in Object Oriented Programming. Define the Rectangle class that will have: Two member variables width and height , A no-arg constructor that will create the default rectangle with width = 1 and height =1.

Create a class Rectangle. The class has attributes length and width , each of which defaults to 1. It has methods that calculate the perimeter and the area of the rectangle.

In Java, you create an object by creating an instance of a class or, in other words, instantiating a class. To create a new object, use Java's new operator. Here's an example using the new operator to create a Rectangle object (Rectangle is a class in the java.awt package).

In this Example, we have declared two classes: Rectangle and RectangleArea. The Rectangle class contains two fields length and breadth of type int that correspond to the length and breadth of the rectangle respectively.
