Java non-access modifiers

• static (Modificatore di non accesso): un metodo che appartiene ad una classe, non ad un oggetto.

• final (Modificatore di non accesso): metodo che vieta la riassegnazione di una variabile in un secondo momento;

• abstract (Modificatore di non accesso): un metodo astratto appartiene ad una classe astratta

Tips and Best Practices

• Use Access Modifiers Wisely: Restrict access as much as possible to protect your data. Use private for fields unless they need to be accessed outside the class.
• Static Usage: Use static for utility methods and constants that do not require object state.
• Final for Constants: Declare constants using final and static to prevent modification.
• Abstract Classes: Use abstract classes as base classes that should not be instantiated directly.
• Synchronized for Thread Safety: Use synchronized to ensure thread safety when necessary, but be aware of potential performance impacts.
• Volatile for Visibility: Use volatile for variables shared between threads to ensure visibility of changes.
• Transient for Serialization: Use transient to exclude fields from serialization when they should not be part of the serialized object.
