What are some examples of interfaces in Java?
In Java, interfaces are used to define a contract for classes. For example, the 'Comparable' interface allows objects to be compared.
Can you give me more examples of built-in interfaces?
Sure! Other built-in interfaces include 'Runnable', 'Callable', and 'Iterable'. Each serves a specific purpose in Java.
How do I create my own interface?
To create your own interface, use the 'interface' keyword. For example: 'public interface MyInterface { void myMethod(); }'.
What is the difference between an interface and an abstract class?
An interface can only contain method signatures and final variables, while an abstract class can have method implementations and state.
