Question

In Java, create a Square class that can be queried for its perimeter and area. Create a second class , with a main(), to test the Square class. Write code in full detail.

Answer 1

The text inside    // //    symbol are the comments *Leave this line*

import java.util.Scanner; //Scanner package used to take user input//
class Square
{
double a;   //varible declaration for side of square//
double are; //variable using to find area//
double peri; //variabe using to find perimeter//
  
   void method() //method to find area and perimeter//
   {
       System.out.println("The formula for the area of the square is : a^2");
       System.out.println("The formula for the perimeter of the square is : 4a");
       System.out.println("Enter side of the square: ");

       Scanner sc=new Scanner(System.in); //Scanner class for user input//
       a=sc.nextDouble();
       are=a*a;   //formula for area of square//
       peri=4*a; //formula for perimeter of square//
       System.out.println("Area of the Square: "+are+"cm/m/km"); //print statement for area///
       System.out.println("Perimeter of the Square: "+peri+"cm/m/km"); //print statement for perimeter//

   }
}
class Second
{
   public static void main(String[] args) { //main method//
       Square s=new Square(); //object of the Square class///
       s.method(); //calling method in Square class with object name//
   }
}
