How do abstract classes and interfaces differ in Java?
Track: Java
Topic: OOP
Focus: Abstract Classes
Java: Abstract Classes
Answer
Abstract classes can have state and concrete methods; interfaces cannot.
Abstract classes can contain fields and fully implemented methods, allowing shared state and behaviors. Interfaces, however, focus on declaring methods without state, supporting multiple inheritance. For example, `AbstractList` in Java can store elements and provide default methods, while `List` interface only defines method signatures.
