   Nov 15, 2015 · To overcome this issue, Java 8 has introduced the concept of default methods which allow the interfaces to have methods with implementation without affecting the classes that implement the interface. The default methods were introduced to provide backward comparability so that existing interfaces can use the lambda expressions without implementing the methods in the implementation class.

   Before Java 8: You could use abstract and regular classes to provide static and default methods. The role of interfaces is clear. All the methods in an interface should be overriden by implementing classes. You can't add a new method in an interface without modifying all the implementations, but this is actually a good thing. After Java 8:

   May 11, 2024 · Java 8 brought a few brand new features to the table, including lambda expressions, functional interfaces, method references, streams, Optional, and static and default methods in interfaces. We’ve already covered a few of these features in another article. Nonetheless, static and default methods in interfaces deserve a deeper look on their own.

   What is a default method in Java 8?

   • So, if a new method is to be added in an interface then its implementation code has to be provided in the class implementing the same interface. To overcome this issue, Java 8 has introduced the concept of default methods which allow the interfaces to have methods with implementation without affecting the classes that implement the interface.

   Why do we use default methods in Java?

   • Default methods helps in resolving Multiple inheritance of behaviour in java. Before Java8, there was support for Multiple inheritance of Type only and now with the help of default methods we can have multiple inheritance of behaviour. For e.g. Java 8 has three rules for resolving conflicts brought upon by multiple inheritance when ambiguous:

   Should interfaces be violated in Java 8?

   • In Java 8, interfaces can contain implemented methods, static methods, and the so-called "default" methods (which the implementing classes do not need to override). In my (probably naive) view, there was no need to violate interfaces like this. Interfaces have always been a contract you must fulfill, and this is a very simple and pure concept.
