Question

W.A.P in Java to accept the diagonal of the square find and display the area and perimeter by using by input stream​

Answer 1

Question:-

➡ Write a program in Java to accept the diagonal of a square and find and display the area and perimeter by using inputstream.

Program:-

import java.io.*;

class Square

{

public static void main(String args[])

{

try

{

BufferedReader br= new BufferedReader(new InputStreamReader(System.in));

System.out.print("Enter the diagonal of the square: ");

double d=Double.parseDouble(br.readLine());

/*

* Diagonal = Side*root 2

* So, side = diagonal/root 2

*/

double s=d/Math.sqrt(2);

s*=4;

System.out.println("Perimeter of the square is: "+s);

s/=4;

s*=s;

System.out.println("Area of the square is: " + s);

}

catch(Exception IO)

{

System.out.println("An error Occurred. Please try again later.");

}

}// main

}// class
