Nonetheless, static and default methods in interfaces deserve a deeper look on their own. In this tutorial, we’ll learn how to use static and default methods in interfaces, and discuss some situations where they can be useful. Further reading: Private Methods in Java Interfaces Learn how t...
因此,如果你在Kotlin代码中尝试调用一个Java 8及以上版本中定义的接口静态方法,并且JVM目标设置为1.6,编译器就会抛出错误:“calls to static methods in java interfaces are prohibited in jvm target 1.6”。这是因为Kotlin编译器无法将这样的调用编译成与Java 6兼容的字节码。

class for all the java classes. So even if we have Object class methods defined as default methods in interfaces, it will be useless because Object class method will always be used. That’s why to avoid confusion, we can’t have default methods that are overriding Object class methods. ...
Interfaces should define the functionality an object provides. This functionality should be overridable and interchangeable (that's why interface methods are virtual). Statics are a parallel concept to dynamic behaviour/virtual methods. Interweaving the two doesn't feel right from a design point to ...
Kindly explain the difference of the two and also if there's an example of when we would use this would be nice. A little confused on Interfaces. Differences between static and default methods in Java 8: 1) Default methods can be overriden in implementing class, while static can...
