1. default方法子类可以实现,也可以选择不实现。 2. static方法不能被继承,也不能被子类实现,只能被自身调用
在接口中,static 关键字修饰的方法为静态方法,与其他静态方法的应用并没有差别 1 2 3 4 5publicinterfaceInterfaceA{staticStringgetName(){return"名字为:InterfaceA"; } } 通过接口名.方法名()直接调用 1 2 3 4publicstaticvoidmain(String[] args){DefaultTesttest=newDefaultTest(); System.out.println(In...
interface中的默认方法（default）和静态方法（static）interface中的默认⽅法（default）和静态⽅法（static）Java8 中接⼝新增了default和static⽅法，这两种⽅法在接⼝中都可以有具体实现。普通的抽象⽅法和default⽅法会被⼦类继承，⼦类必现实现普通抽象⽅法，⽽default⽅法⼦类可以实现，也...
