-* Modifiers.
-
-** public.
-
- * Public class is visible in other packages.
- * Public field is visible everywhere (class must be public too).
-
-** private.
-
- * Private variables or methods may be used only by an instance of the same
- class that declares the variable or method
- * A private feature may only be accessed by the class that owns the feature.
-
-** protected.
-
- * Is available to all classes in the same package and also available to all
- subclasses of the class that owns the protected feature.
- * This access is provided even to subclasses that reside in a different
- package from the class that owns the protected feature.
-
-** default.
-
-What you get by default ie, without any access modifier.
-
- * It means that it is visible to all within a particular package.
-
-* static.
-
- * Static means one per class, not one for each object no matter how many
-   instance of a class might exist. This means that you can use them without
-   creating an instance of a class.
- * Static methods are implicitly final, because overriding is done based on
-   the type of the object, and static methods are attached to a class, not an
-   object.
- * A static method in a superclass can be shadowed by another static method in
-   a subclass, as long as the original method was not declared final.
- * You can't override a static method with a nonstatic method.
-
-* final.
-
- * A final class can't be extended ie., final class may not be subclassed.
- * A final method can't be overridden when its class is inherited.
- * You can't change value of a final variable.
-
-* Exceptions.
-
-A checked exception is some subclass of Exception (or Exception itself),
-excluding class RuntimeException and its subclasses.
-
-Unchecked exceptions are RuntimeException and any of its subclasses. Class
-Error and its subclasses also are unchecked. With an unchecked exception,
-however, the compiler doesn't force client programmers either to catch the
-exception or declare it in a throws clause.
-
-* Inner classes.
-
-** Nested top-level classes.
-
-If you declare a class within a class and specify the static modifier, the
-compiler treats the class just like any other top-level class.
-
-Any class outside the declaring class accesses the nested class with the
-declaring class name acting similarly to a package. eg, outer.inner. Top-level
-inner classes implicitly have access only to static variables. There can also
-be inner interfaces. All of these are of the nested top-level variety.
-
-** Member classes.
-
-Member inner classes are just like other member methods and member variables
-and access to the member class is restricted, just like methods and variables.
-This means a public member class acts similarly to a nested top-level class.
-
-The primary difference between member classes and nested top-level classes is
-that member classes have access to the specific instance of the enclosing
-class.
-
-** Local classes.
-
-Local classes are like local variables, specific to a block of code. Their
-visibility is only within the block of their declaration. In order for the
-class to be useful beyond the declaration block, it would need to implement a
-more publicly available interface.
-
-Because local classes are not members, the modifiers public, protected,
-private, and static are not usable.
-
-** Anonymous classes.
-
-Anonymous inner classes extend local inner classes one level further. As
-anonymous classes have no name, you cannot provide a constructor.
