The Programming Section for ‘Rectangle Area Calculation in Java’

import java.util.Scanner; 
// Create a Scanner object
Scanner myObj = new Scanner(System.in); 
// Prompt for the length
System.out.println('Enter length of rectangle'); 
int length = myObj.nextInt(); 
// Prompt for the width
System.out.println('Enter width of rectangle'); 
int width = myObj.nextInt(); 
// Compute the area
int area = length * width; 
// Print the result
System.out.println('Area of Rectangle is ' + area);  

Explanation of the ‘Area of Rectangle Program in Java’ Code

  • Firstly, we import the Scanner class from the java.util package.
  • Next, we create an object of the Scanner class to accept input from the user.
  • We then prompt the user to enter the length of the rectangle and store this value in the ‘length’ variable.
  • The user is then asked to enter the width of the rectangle, and this value is stored in the ‘width’ variable.
  • Finally, we calculate the area of the rectangle by multiplying the length and the width, and the result is displayed on the screen.


Enter length of rectangle
Enter width of rectangle
Area of Rectangle is 30
