For this example we will be looking at the code below.
These fields and methods are represented by the class diagram below.
Notice that before this we have kept all fields and methods in alphabetical order. When we introduce private this will change the order of things. Instead of private fields and method being alphabetical they will all be pushed to below the public fields/methods and keep their alphabetical order there.
The major distinction between public and private fields is that the + turns into a - and the first character changes to lower-case. However, private methods do not change their first character to lower-case.
