In computer programming, a runtime system or runtime environment is a sub-system that exists both in the computer where a program is created, as well as in the computers where the program is intended to be run. Polymorphism means "many forms", and it occurs when we have many classes that are related to each other by inheritance. It is used to call superclass methods, and to access the superclass constructor. Method: An abstract method can only be used in an abstract class, and it does not have a body. The name comes from the compile time and runtime division from compiled languages, which similarly distinguishes the computer processes involved in the creation of a The interface keyword is used to declare a special type of class that only contains abstract methods.. To access the interface methods, the interface must be "implemented" (kinda like inherited) by another class with the implements keyword (instead of extends).The body of the interface method is provided by the "implement" class. As the database may be viewed through three levels of abstraction, any change at any level can affect other levels' schemas. COLOR PICKER. Another way to achieve abstraction in Java, is with interfaces. You will learn more about these in the Java Modifiers Chapter.

You can use any directory name, like c:/user (windows), or, if you want to keep the package within the same directory, you can use the dot sign ". An enum can, just like a class, have attributes and methods.The only difference is that enum constants are public, static and final (unchangeable - cannot be overridden)..
