Kotlin中的抽象类与接口相似，但有一个重要区别。抽象类的属性不是必须抽象的或提供访问器实现的。关键字interface用于在Kotlin中定义接口。例如，这里，这是类或对象如何实现接口的方法：在这里，InterfaceImp 类实现了 MyInterface 接口。该类重写接口的抽象成员（test属性 和 foo()方法）。运行该程序时...
The method is non-abstract and declared in Person class (and not declared in Teacher class). Recommended Reading: Kotlin Interfaces Kotlin interfaces are similar to abstract classes. However, interfaces cannot store state whereas abstract classes can. Meaning, interface may have property but it ...
In the final example, we used abstract class and interface; it has the same feature as abstract class. An interface contains a non-abstract method like sample1(); similar to the abstract class, it contains both abstract and non-abstract methods. Finally, the object was created in the main ...

interface AppComponent : AndroidInjector<MyApplication> { @Component.Builder abstract class Builder : AndroidInjector.Builder<MyApplication>() } 注意:请阅读上面代码段中的内联评论。 我想要的只是将HomeViewModel设置为抽象类,并在需要的地方进行注入。

关键字interface用于在Kotlin中定义接口。例如, interfaceMyInterface{vartest:String//抽象属性funfoo()//抽象方法funhello()="Hello there"//具有默认实现的方法} 这里, 创建接口 MyInterface。 该接口有一个抽象属性 test 和一个抽象方法 foo()。 该接口还具有非抽象方法 hello()。

Kotlin 2.0 produces a compiler error in our generated AbstractSpringDAOImpl class that I could reproduce like this: Java base class: package test; import org.jetbrains.annotations.NotNull; import java.util.List; import java.util.Optional; public interface I<T> { List<@NotNull T> list(); Op...
