Java Program to Find the Area and Perimeter of Rectangle using Class

This is a Java Program to Create a Simple Class to Find out the Area and Perimeter of Rectangle.
Perimeter of rectangle = 2 * (length + breadth)
Area of rectangle = length * breadth

Enter the length and breadth of the rectangle as input. Now we use the given formula to calculate the area and perimeter of rectangle.

Here is the source code of the Java Program to Create a Simple Class to Find out the Area and Perimeter of Rectangle. The Java program is successfully compiled and run on a Windows system. The program output is also shown below.

  1. import java.util.Scanner;
  2. public class Area_Perimeter 
  3. {
  4.     public static void main(String[] args) 
  5.     {
  6.         int l, b, perimeter, area;
  7.         Scanner s = new Scanner(;
  8.         System.out.print("Enter length of rectangle:");
  9.         l = s.nextInt();
  10.         System.out.print("Enter breadth of rectangle:");
  11.         b = s.nextInt();
  12.         perimeter = 2 * (l + b);
  13.         System.out.println("Perimeter of rectangle:"+perimeter);
  14.         area = l * b;
  15.         System.out.println("Area of rectangle:"+area);
  16.     }
  17. }


$ javac Area_Perimeter .java
$ java Area_Perimeter 
Enter length of rectangle:4
Enter breadth of rectangle:5
Perimeter of rectangle:18
Area of rectangle:20
