In the example above we have Donna and Red both nested classes of Eric. Remember Eric is the top level class so it can’t be made static. So, that leaves us with Donna and Red. Eric is in love with Donna, meanin
An object class in Java is the POJO class. It includes business logic. In a Model View Controller architecture, after viewing, the controller would communicate with the business logic, which would then get in touch with the Java POJO class to retrieve the data. The phrase "business logic" d...
Static methods cannot be overriddenbecause they are not dispatched on the object instance at runtime. The compiler decides which method gets called. Static methods can be overloaded (meaning that you can have the same method name for several methods as long as they have different parameter types)...
If a class is useful to only one class, it makes sense to keep it nested and together. It helps in the packaging of the classes. Java inner classes implements encapsulation. Note that inner classes can access outer class private members and at the same time we can hide inner class from ...
From the above introduction, it is now clear that to make anything final we just have to add a final prefix to it. So to make a final class in Java, add a final keyword in front of the class. A final class in Java cannot be inherited or extended, meaning that no subclass can be...
This method will parse the authenticate header as plainly as possible, meaning no casing will be changed on the scheme and no decoding will be done on the parameters. The only processing done is removal of quotes around parameter values and backslashes escaping values. Ex, "va\"lue" will be...
The‘Fruit’class is declared abstract, meaning it can’t be directly instantiated. Within the‘Fruit’class, there’s an abstract method called‘taste(),’which lacks a concrete implementation. The‘Apple’class, a subclass of‘Fruit’, provides the specific implementation for the‘taste()’meth...

At the member level, you can also use the public modifier or no modifier (package-private) just as with top-level classes, and with the same meaning. For members, there are two additional access modifiers: private and protected. The private modifier specifies that the member can only be acc...
