Java Programming for Complete Beginners - Java 16 - Java Tip 16 - Quick Look at Inbuilt Enums - Month, DayOfWeek

The video tutorial covers the basics of enums in Java, demonstrating how to create and use an enum called 'season'. It explains that enums can exist independently or within a class. The tutorial explores enums in the Java API, focusing on 'Day of the Week' and 'Month' enums, and their practical applications. It highlights the concept of 'primitive obsession' and encourages using enums to restrict values to a specific set, making programming more efficient.

What is one of the key characteristics of an enum in Java?

• Enums are only used for numbers.

• Enums cannot be made public.

• Enums can exist independently of a class.

• Enums must always be inside a class.

Which of the following is an example of an enum in the Java API?

• Size

• DayOfWeek

• Shape

• Color

How can you create a specific month using the Month enum in Java?

• By using a boolean value.

• By passing a number corresponding to the month.

• By using a float value.

• By passing a string of the month's name.

What is 'primitive obsession' in programming?

• Using enums for all data types.

• Relying on strings and numbers instead of enums.

• Avoiding the use of classes.

• Using too many primitive data types.

Why should you consider using enums when dealing with a fixed set of values?

• Enums are easier to write than classes.

• Enums provide a type-safe way to handle fixed values.

• Enums can store unlimited values.

• Enums are faster than arrays.
