Definitions: A class that is derived from another class is called a subclass (also a derived class, extended class, or child class). The class from which the subclass is derived is called a superclass (also a base class or a parent class). Excepting Object, which has no superclass, eve...
假设类 Derived 继承了类 Base,类 C 有一个原型为m(Base)的方法,则在下面的代码中,编译器隐式地将类 Derived 的对象 derived 转化为类 Base 的对象。这种隐式的转换使方法m(Base)使用所有能转换成 Base 类的所有参数。 C c = new C(); Derived derived = new Derived(); c.m(derived); 隐式的强制...

已存在的类成为超类(superclass)、基类(base class)或父类(parent class);新类称为子类(subclass)、派生类(derived class)或孩子类(child class)。 注释: 有些人认为 super 与 this 引用是类似的概念 , 实际上 , 这样比较并不太恰当 。 这是因为 super 不是一个对象的引用 , 不能将 super 赋给另一个...
Constructs a new throwable with the specified cause and a detail message of(cause==null ? null : cause.toString())(which typically contains the class and detail message ofcause). This constructor is useful for throwables that are little more than wrappers for other throwables (for example,java...
Netty使用中出现java.base/java.lang.String cannot be cast to io.netty.buffer.ByteBuf 原因:解码器用错,客户端或服务端选择ByteBuf封装消息,但是ChannelInitializer继承类中使用了String的解码器,String不能转成ByteBuf,把消息解码成String抛出来了。 解决方法:1.去掉解码器...
this usually requires the developer to cast the popped reference back to some more specific object-derived class so that some meaningful operation(s) can be performed, but in reality the type of all objects that exists on any stack instance should really be known at compile-time by the develo...
