public abstractclassB {public static voidmain(String[] args){System.out.println("I am inside abstract class");}}public enumC {;public static voidmain(String[] args){System.out.println("I am inside enum");}} How to call static method of an Interface?
有 4 种类型的方法引用,如表 2-2 所示。 1.2.1 静态方法引用 Static Method References 静态方法引用的语法只需要类与静态方法名,中间通过两个 冒号分隔。例如: String::valueOf Integer::compare 对数组 integerArray 排序就可以调用: Arrays.sort(integerArray, (x,y) -> Integer.compareUnsigned(x, y)); ...

任何一个 interface{} 类型的变量都包含了2个指针,一个指针指向值的类型,对应 pair 中的 type,这个 type 类型包括静态的类型 (static type,比如 int、string...)和具体的类型(concrete type,interface 所指向的具体类型),另外一个指针指向实际的值,对应 pair 中的 value。
public static void getStaticMethod1(){ System.out.println("InterfaceJava8Test1的静态方法"); } // 默认方法 public default void getDefaultMethod2(){ System.out.println("InterfaceJava8Test1的默认方法"); } } 1. 2. 3. 4. 5. 6. 7. ...
public class MyReflection { public static void main(String[] args) throws Exception { MyTest myTest = new MyTest(); Class<MyTest> c = MyTest.class; Method method = c.getMethod("output", new Class[] {}); //如果MyTest类名上有注解@MyAnnotation修饰,则为true if(MyTest.class.isAnnotat...

Method If you configure inports as Method, a set method appears for each inport. If you configure outports as Method, a get method appears for each outport in the model. If you configure the other model element categories as Method, an aggregate structure-based get and set method appears ...
