1. Add a field to the Hexagon.java class called side. It should be a double. 2. Write a no arguments constructor. Set side = 0.0 3. Write a constructor that accepts a double parameter. Set side equal to the value passed in. 4. Write accessor/muteator methods for the field side 5. Write a method (getPerimeter0) that returns a double and calculates the perimeter of the Hexagon. The formula for this is: perimeter = side * 6 6. Write a method (getDiagonalLength0) that returns a double that is the distance from one 'corner' to its opposite 'corner. The formula for this is: diagonalLength = side * 2 7. Write a method (getArea) which returns a double containing the surface area of the hexagon. The formula for this is (3/2 * sqrt(3) * side ^ 2). Take care with integer division here.
