5.You can write a new instance method in the subclass that has the same signature as the one in the superclass, thus overriding it. 6.You can write a new static method in the subclass that has the same signature as the one in the superclass, thus hiding it. ...
method overriding in Java. If you remember I shared one real-life story in Inheritance chapter and I am pretty sure that story would have helped you in understanding the Inheritance in a better manner. Similar to that, again I am going to share one of the real stories in this chapter as...
注意此处的一个小细节:若你自己运行这个案例你得到的参数名称可能是hello.args0等,而我此处是形参名。是因为我使用Java8的编译参数:-parameters(此处说一点:若你的逻辑中强依赖于此参数,务必在你的maven中加入编译插件并且配置好此编译参数) 若需要校验方法返回值,改写如下: ...
