What are the differences between default methods and abstract methods in Java?
An example of an AI chatbot conversation about Java default methods and abstract methods.
What are the differences between default methods and abstract methods in Java?
Default methods in Java provide a default implementation, while abstract methods must be implemented by subclasses.
Can you give me an example of each?
Sure! A default method can be defined in an interface like this: default void myMethod() { System.out.println("Default implementation"); }. An abstract method looks like this: abstract void myAbstractMethod();.
When should I use default methods?
Use default methods when you want to add new functionality to an interface without breaking existing implementations.
Are there any limitations to using default methods?
Yes, default methods cannot be overridden if they are final, and they cannot be static.
