方法的重写(Overriding)和重载(Overloading)是java多态性的不同表现,重写是父类与子类之间多态性的一种表现,重载可以理解成多态的具体表现形式。 (1)方法重载是一个类中定义了多个方法名相同,而他们的参数的数量不同或数量相同而类型和次序不同,则称为方法的重载(Overloading)。
@Override annotation is used when a developer overrides a function in Java to use the same function name but assign these functions with different properties. If you are aware of over rise functions in Java but have not been using @override annotation since you did not feel like using it as...
