I believe the reason why the first set of properties will not work is because there is no auto value for display, so that property should be ignored. In that case, inline-table will still take effect, and as width do not apply to inline elements, that set of properties will not do anything. The second … Read more

In Java, the equals() method that is inherited from Object is: public boolean equals(Object other); In other words, the parameter must be of type Object.

In the example you’ve given, by declaring the class variable with the name ‘me’ in class Son you hide the class variable … Read more
Java supports* covariant return types for overridden methods. This means an overridden method may have a more specific return type. That is, as long as the new return type is assignable to the return type of the method you are overriding, it’s allowed. For example: class ShapeBuilder { … public Shape build() { …. } … Read more

If you’re replacing one implementation completely with another, it’s “overwriting” or more commonly “replacing“. If you’re replacing an implementation with another for some specific cases, it’s “overriding“. To “overwrite” something is to put something else in its place, destroying the thing overwritten.
