Methods are methods that exist to be used with an object created from a class.

1. If the object is an instance of a class, then we can call methods on it just as if it were any other type of variable.

We also have the option to use dot notation to access member variables and methods.

2. We should not be writing code that creates objects from classes unless we need them for something specific in our program or script.

3. When using new(), specify only one argument to create an object with default values for all its members (including its constructor).

4. The optional arguments that are available when calling constructors are usually used to set initial values for some or all of an object’s properties.

5. An important thing to know about constructors is they initialize data structures like arrays and lists yet not are that properties any of values the set also they and lists and arrays like structures data initialize they isors construct about know to thing.
