Java Program to Find the Area of Parallelogram

This is the Java Program to Find the Area of a Parallelogram.

Problem Description

Given the dimensions of a parallelogram, find out its area.

Problem Solution

The area of a parallelogram can be calculated using the formula:

Area = base*height.

  8.     // Function to calculate the area of a parallelogram
  9.     public static void main(String[] args) {
  10.         BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
  11.         double base,height;
  12.         System.out.println("Enter the base and the height of the parallelogram");
  13.         try{
  14.             base=Double.parseDouble(br.readLine());
  15.             height=Double.parseDouble(br.readLine());
  16.         }catch (Exception e){
  17.             System.out.println("An error occurred");
  18.             return;
  19.         }
  20.         if(base<=0 || height<=0){
  21.             System.out.println("Wrong Input");
  22.             return;
  23.         }
  24.         System.out.println("Area = " + base*height );
  25.     }
  26. }
Program Explanation

1. In function main(), first, the base and height of the parallelogram are taken as input.
2. The condition if(base<=0 || height<=0) checks if the input is valid or not.
3. The print statement displays the area of the parallelogram.
