public static void main(String[] args) {

 try (Scanner scanner = new Scanner(System.in)) {

  System.out.printf("1. Enter side of square : ");

  double side = scanner.nextDouble();  

   

  //Area of square is side * side

  double area = side * side;

  //Print area up to two precision

  System.out.printf("2. Area of square is : %4.2f",area);

 

  //Area of square is side * side

  double Perimeter = 4 * side;

  //Print area up to two precision

  System.out.printf("\n3. Perimeter of square is : %4.2f",Perimeter);
