Need help with design patterns

quinnd6

Ok Ive got a project due in tomorrow and I need to know if the below code is in the form of a facade design pattern ?
It calls one big method in the project 4 class which creates instances of the student and supervisor classes and its own class.


Is this a facade?

public class TableFacade
{
TableFacade()
{
System.out.println("This is the table of projects");
}

public Project4 makeTheTable()
{


Supervisor5 sup = new Supervisor5();
Project4 project =new Project4();
project.readRelevantProjectsFromFile(sup);


return project;
}
}

Im trying to adapt from my project4 class
is this in the adaptor pattern?



class AdaptProject
{
Project4 project;
Supervisor5 supervisor;

void readProjectDetails()
{

project.readProjectDetails();


}

void readRelevantProjectsFromFile(Supervisor5 v)
{
project.readRelevantProjectsFromFile(supervisor);

}

String projName()
{
return project.projName;
}
String projSubject()
{
return project.projSubject;
}
}

As these are patterns they are open to interpretation but:

In general the Facade pattern wraps an existing class, and simplifies it. So for something to be a facade pattern it should really wrap only one other class and provide a simpler way of accessing (its over-complex methods)

The simplest way to think of an Adaptor pattern (at least in java terms) is a new class that wraps another one so that it now implements an interface.

- There should be an existing interface (that code already uses)
- There should be an existing class that doesn't implement that interface.
- The Adaptor class implements both wraps the existing class *AND* implements the interface.

I would say a facade could wrap one or more classes.
