In object-oriented computer programming, a null object is an object with no referenced value or with defined neutral (null) behavior.The null object design pattern, which describes the uses of such objects and their behavior (or lack thereof), was first published as "Void Value" [1] and later in the Pattern Languages of Program Design book series as "Null Object".
An example of the application of marker interfaces from the Java programming language is the Serializable interface: package java.io ; public interface Serializable { } A class implements this interface to indicate that its non- transient data members can be written to an ObjectOutputStream .
This is a list of the instructions that make up the Java bytecode, an abstract machine language that is ultimately executed by the Java virtual machine. [1] The Java bytecode is generated from languages running on the Java Platform, most notably the Java programming language.
is the text editor in PC DOS 6, PC DOS 7 and PC DOS 2000. Proprietary: ed: The default line editor on Unix since the birth of Unix. Either ed or a compatible editor is available on all systems labeled as Unix (not by default on every one). Free software: ED: The default editor on CP/M, MP/M, Concurrent CP/M, CP/M-86, MP/M-86, Concurrent CP/M-86 ...
In software design, the Java Native Interface (JNI) is a foreign function interface programming framework that enables Java code running in a Java virtual machine (JVM) to call and be called by [1] native applications (programs specific to a hardware and operating system platform) and libraries written in other languages such as C, C++ and assembly.

A snippet of Java code with keywords highlighted in bold blue font. The syntax of Java is the set of rules defining how a Java program is written and interpreted. The syntax is mostly derived from C and C++. Unlike C++, Java has no global functions or variables, but has data members which are also regarded as global variables.
Furthermore, J++ applications did not conform to the same standardized method of accessing the underlying operating system functions as any other Java application under Sun's Java SDK. In Microsoft 's implementation, an underlying framework called J/Direct provided a base mechanism that allowed J++ applications to completely circumvent Java's ...
