What are enums in Java and how do I use them?
Enums in Java are a special data type that enables a variable to be a set of predefined constants. They are useful for representing a fixed set of related values.
Can you give me an example of how to define an enum?
Sure! You can define an enum like this: enum Day { SUNDAY, MONDAY, TUESDAY, WEDNESDAY, THURSDAY, FRIDAY, SATURDAY }; This creates an enum called Day with seven constants.
How do I use enums in a switch statement?
You can use enums in a switch statement like this: switch(day) { case MONDAY: // do something; break; ... }. This allows you to execute different code based on the enum value.
Are there any advantages to using enums over constants?
Yes, enums provide type safety, better organization, and can have methods and fields, making them more powerful than simple constants.
