The difference between Overload and Override

Overloaded Overload means that there can be multiple methods with the same name in the same class, but these methods have different parameter lists, that is, different parameter parameters or parameter types. Of course, the return values can be different when overloaded, but if the parameter list is exactly the same, you cannot overload through inconsistent return types, which is not allowed.

Overriding Override means that the method in the subclass can have exactly the same name and parameters as the method in the parent class. When this method is called through an object created by the subclass, the method defined in the subclass is called, that is, the method in the subclass overrides the method of the parent class. When a subclass overrides a parent method, it can only throw fewer or smaller exceptions than the parent class. The return of the overridden method must be consistent with that of the overridden method.

Boolean type, which is the basic data type that represents logical values.
