在Java中“匿名类仅实现接口或扩展类而不同时扩展类”的原因是什么？

Question

I have read Anonymous class can only implement the interface or extend the class but not both. But I don't know what is the key reason behind it to prevent both at the same time?

Please enlighten me on this...

Answer 1

Because anonymous class basically doesnt has any name. So you basically cannot write

Class someClass extends SomeOtherClass implements SomeInterface

you do it like

new SomeClass/SomeInterface(){
  @override
  public void someMethod(){
  }
};
