So rather than initiating edge within tetrahedron, we initiate it beforehand and instead access it using a pointer? Noting that the interface is a separate document as my IDE needs it apart from classes — Twisted Fate. Tsk, the other person who was talking about polymorphism deleted their post and didn't catch their name. Wanted to pick their brain on that a little.
It's amazing how much a simple relevant example can help versus telling someone to look at the same theory documents. Sign up or log in Sign up using Google. Sign up using Facebook.

Featured on Meta. New post summary designs on greatest hits now, everywhere else eventually. This is a simple Area Calculator coded in Java. What this does is that it prompts the user to select a shape, and asks for the details needed to calculate the area of that specific shape.
Making a package for a one-class program seems like overkill. You would be better off naming the class AreaCalculator , which would be more meaningful than Main. This has no effect on performance.
The compiler will embed just one long string constant in the bytecode. A chain of if-elses would be better written using a switch block. Not only is it easier to see the patten at a glance, it is also more efficient, in that it compiles to a single tableswitch opcode.
Since there are so many places where you write System. Should you later decide to add validation and error handling, you can implement it in one central place. I suggest changing System. I don't see any reason why the inputs should be restricted to int s. You could just as easily accept double s. I recommend splitting each calculation into a separate function, to ensure that they do not interfere with each other.
For example, if you were to add support for parallelograms and trapezoids, you might have a conflict for a variable named height , if you lumped everything into main. The resulting main would be just a menu. Using package com. The idea is to produce unique Java namespaces by leveraging the uniqueness of internet domain names. It's a convention designed for the age of the internet and a sound strategy for avoiding namespace conflicts. It makes assigning responsibility a more reasoned process: only one or none of the packages can be named correctly.
My apologies if I am in error. This limit, if there is one, is defined by the particular implementation that is used. Each call to this method returns a fresh PathIterator object that traverses the Shape object geometry independently from any other PathIterator objects in use at the same time. Parameters: at - an optional AffineTransform to be applied to the coordinates as they are returned in the iteration, or null if untransformed coordinates are desired flatness - the maximum distance that the line segments used to approximate the curved segments are allowed to deviate from any point on the original curve Returns: a new PathIterator that independently traverses a flattened view of the geometry of the Shape.

Float public interface Shape The Shape interface provides definitions for objects that represent some form of geometric shape. The Shape is described by a PathIterator object, which can express the outline of the Shape as well as a rule for determining how the outline divides the 2D plane into interior and exterior points. Each Shape object provides callbacks to get the bounding box of the geometry, determine whether points or rectangles lie partly or entirely within the interior of the Shape , and retrieve a PathIterator object that describes the trajectory path of the Shape outline.
Method Summary Methods Modifier and Type Method and Description boolean contains double x, double y Tests if the specified coordinates are inside the boundary of the Shape , as described by the definition of insideness. Tests if the interior of the Shape entirely contains the specified rectangular area.
