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//
   }
}

Implement the Shape hierarchy -- create an abstract class called Shape, which will be the parent class to TwoDimensionalShape and ThreeDimensionalShape. The classes Circle, Square, and Triangle should inherit from TwoDimensionalShape, while Sphere, Cube, and Tetrahedron should inherit from ThreeDimensionalShape. Each TwoDimensionalShape should have the methods getArea() and getPerimeter(), which calculate the area and perimeter of the shape, respectively. Every ThreeDimensionalShape should have the methods getArea() and getVolume(), which respectively calculate the surface area and volume of the shape. Every...
