The fragile base class problem is a fundamental architectural problem of object-oriented programming systems where base classes (superclasses) are considered "fragile" because seemingly safe modifications to a base class, when inherited by the derived classes, may cause the derived classes to malfunction. The programmer cannot determine whether ...
This makes it possible (for example): to load or unload classes at runtime (for example to load libraries dynamically at runtime, even from an HTTP resource). This is an important feature for: implementing scripting languages, such as Jython; using bean builders; allowing user-defined extensibility; allowing multiple namespaces to communicate.
The classpath tells Java where to look in the filesystem for files defining these classes. The virtual machine searches for and loads classes in this order: 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 ...
In object-oriented programming, a class defines the shared aspects of objects created from the class. The capabilities of a class differ between programming languages, but generally the shared aspects consist of state and behavior that are each either associated with a particular object or with all objects of that class.
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.
Also, another common example is that a person object created from a child class cannot become an object of parent class because a child class and a parent class inherit a person class but class-based languages mostly do not allow to change the kind of class of the object at runtime. For class-based languages, this restriction is essential in ...
Real time Java is a catch-all term for a combination of technologies that allows programmers to write programs that meet the demands of real-time systems in the Java programming language. Java's sophisticated memory management, native support for threading and concurrency, type safety, and relative simplicity have created a demand for its use ...
A typical implementation model of Java-RMI using stub and skeleton objects. Java 2 SDK, Standard Edition, v1.2 removed the need for a skeleton. The Java Remote Method Invocation (Java RMI) is a Java API that performs remote method invocation, the object-oriented equivalent of remote procedure calls (RPC), with support for direct transfer of serialized Java classes and distributed garbage ...
