Question

public class Rectangle private double width; private double height; public Rectangle (double w, double h) { width=w; height=h; } public double getArea() { return (width*height); > public static void main(String[] args) { Rectangle Ri=new Rectangle (2,6); Rectangle R2=new Rectangle (4,5); System.out.println("Rectangle 1 area is System.out.println("Rectangle 2 area is "+R1.getArea()); "+R2.getArea());

Answer 1

The question involves the use of Java programming language to compute areas of rectangles by utilizing classes, constructors, and methods. The code demonstrates object creation and method invocation.

Step-by-step explanation:

The question is related to the subject of Computers and Technology and is most likely at the High School level. The programming language used in the question is Java, which is often taught in high school and college computer science courses. The question refers to a Java class called Rectangle and involves the calculation of the area of rectangular shapes. The main focus is to understand how objects are created and methods are called within the Java programming language.

To calculate the area of each Rectangle object, you must call the getArea() method after creating each Rectangle instance with the specified width and height. The code provided has a minor typo with the instantiation of the rectangular objects (it uses 'Ri' instead of 'R1') and the print statements are incomplete. Once corrected, the output will display the areas of both Rectangle 1 and Rectangle 2.
