The Application Foundation Classes (AFC) were a graphical framework for building Java-based graphical user interfaces (GUIs), developed by Microsoft and shipped as part of the Microsoft SDK for Java. AFC was based on the Abstract Window Toolkit (AWT), but its architecture made it easier to extend components to better fit user needs.
bootstrap classes: the classes that are fundamental to the Java Platform (comprising the public classes of the Java Class Library, and the private classes that are necessary for this library to be functional). extension classes: packages that are in the extension directory of the Java Runtime Environment or JDK, jre/lib/ext/
Design patterns can be viewed as formalized best practices that the programmer may use to solve common problems when designing a software application or system. Object-oriented design patterns typically show relationships and interactions between classes or objects, without specifying the final application classes or objects that are involved.
The Java Virtual Machine is expected to be able to take advantage of the additional constraints of value classes to eliminate heap allocation of value types in the vast majority of cases. However, storing instances of value classes into a field or upcasting them to an interface will still require an allocation.
A general interface between Java and the native system, used for windowing, events, and layout managers. This API is at the core of Java GUI programming and is also used by Swing and Java 2D. It contains: The interface between the native windowing system and the Java application; The core of the GUI event subsystem; Several layout managers;
The following is a common set of access specifiers: [10] Private (or class-private) restricts access to the class itself. Only methods that are part of the same class can access private members. Protected (or class-protected) allows the class itself and all its subclasses to access the member. Public means that any code can access the member by ...
The Java Class Library (JCL) is a set of dynamically loadable libraries that Java Virtual Machine (JVM) languages can call at run time. Because the Java Platform is not dependent on a specific operating system , applications cannot rely on any of the platform-native libraries.
An interface in the Java programming language is an abstract type that is used to declare a behavior that classes must implement. They are similar to protocols.Interfaces are declared using the interface keyword, and may only contain method signature and constant declarations (variable declarations that are declared to be both static and final).
