Multiple methods in the same class can have the same name. They're called overloaded methods.
In C#, a class can have multiple
methods with the same name.
0:00
For example, there are 18 methods in
the console class all named write.
0:03
They all take different types and
numbers of arguments.
0:08
This is useful because not all data that a
method can handle comes in the same type.
0:11
The DistanceTo method right now calculates
the distance between a point and
0:18
the x and y values parsed in.
0:22
We could also have
a DistanceTo method that
0:24
calculates the distance
between two-point objects.
0:28
This method can just call the other
DistanceTo method like this.
0:34
What we've just done is
overloaded the DistanceTo method.
0:48
To overload a method means to have two
methods with the same name that take
0:51
different parameters.
0:56
As you can see,
methods are the moving parts of an object.
0:57
It's where the code that does stuff lives.
1:01
Fields in a class
are the substance of the object.
1:04
They're what make two objects
of the same type unique.
1:08
They contain the object's data.
1:12
You may have also noticed that methods
all use the fields in some way.
1:15
This is something you'll
see throughout this course.
1:20
One of the purposes of objects
is to combine data and
1:23
the methods that are closely tied to
the data together in one elegant package.
1:27
Now that we've learned how to model
an object using attributes and behaviors,
1:32
we can go on to learn some of the core
principles of object-oriented programming.
1:37
This is where it gets really interesting.
