The difference between static and non-static:

1) in non-static, there can be either an instance member or a static member.

2) When invoking an instance member, you need to use the object name. Instance Members

When you call a static member, you need to use the class name. Static member name

Summarize:

1) Static members must be called using the class name, and instance members are invoked using the object name

2) In an instance function, you can use either a static member or an instance member

3) in a static function, only static members are accessible, and access to instance members is not allowed

Use:

1) If you want your class to be used as a "tool class," consider writing the class as a static

2) Static classes share resources throughout the project
