方法的覆盖在Object Pascal覆盖一个方法用来实现OOP的多态性概念。通过覆盖使一方法在不同的派生类间表现出不同的行为。Object Pascal中能被覆盖的方法是在声明时被标识为virtual或dynamic的方法。为了覆盖一个方法，在派生类的声明中用override代替virtual或dynamic。typeTParent = classpublicprocedure mySing...

在Java中,静态方法(static methods)不能被标注为@Override,这是因为静态方法属于类级别的方法,而不是实例级别的方法。下面我将详细解释原因,并提供正确的使用@Override注解的场景或方法,以及在静态方法中实现类似@Override功能的替代方案。 1. 为什么静态方法不能被标注为@Override 静态方法不属于多态:重写(Override)的...

在Java中,抽象方法(abstract method)不能声明为静态(static)。原因如下: 1. **抽象方法的本质**:抽象方法没有方法体,必须通过子类继承后被重写(override)才能使用。子类的具体实现是对抽象方法的完整定义。 2. **静态方法的特性**:静态方法属于类级别(class-level),不依赖于对象实例。它不能被子类重写,仅能在...
You cannot expand the accessibility, meaning you cannot make the overriding method more accessible than the method it overrides. For example, if the base class method is Protected, you cannot override it with a Public method.Error ID: BC32203...
