  2. Java memory model - Wikipedia

    en.wikipedia.org/wiki/Java_memory_model

    The original Java memory model developed in 1995, was widely perceived as broken, [1] preventing many runtime optimizations and not providing strong enough guarantees for code safety. It was updated through the Java Community Process, as Java Specification Request 133 (JSR-133), which took effect back in 2004, for Tiger (Java 5.0). [2] [3]

  3. Comment (computer programming) - Wikipedia

    en.wikipedia.org/wiki/Comment_(computer_programming)

    An illustration of Java source code with prologue comments indicated in red and inline comments in green. Program code is in blue.. In computer programming, a comment is a programmer-readable explanation or annotation in the source code of a computer program.

  4. Code mobility - Wikipedia

    en.wikipedia.org/wiki/Code_Mobility

    The purpose of code mobility is to support sophisticated operations. For example, an application can send an object to another machine, and the object can resume executing inside the application on the remote machine with the same state as it had in the originating application.

  5. Comparison of Java and C++ - Wikipedia

    en.wikipedia.org/wiki/Comparison_of_Java_and_C++

    Compiled Java code files are generally smaller than code files in C++ as Java bytecode is usually more compact than native machine code and Java programs are never statically linked. C++ compiling features an added textual preprocessing phase, while Java does not. Thus some users add a preprocessing phase to their build process for better ...

  6. Naming convention (programming) - Wikipedia

    en.wikipedia.org/wiki/Naming_convention...

    Java compilers do not enforce these rules, but failing to follow them may result in confusion and erroneous code. For example, widget.expand() and Widget.expand() imply significantly different behaviours: widget.expand() implies an invocation to method expand() in an instance named widget, whereas Widget.expand() implies an invocation to static ...

  7. Domain-specific language - Wikipedia

    en.wikipedia.org/wiki/Domain-specific_language

    ColdFusion's associated scripting language is another example of a domain-specific language for data-driven websites. This scripting language is used to weave together languages and services such as Java, .NET, C++, SMS, email, email servers, http, ftp, exchange, directory services, and file systems for use in websites.

  8. Write once, run anywhere - Wikipedia

    en.wikipedia.org/wiki/Write_once,_run_anywhere

    The installation of a JVM or Java interpreter on chips, devices, or software packages became an industry standard practice. A programmer could develop code on a PC and expect it to run on Java-enabled mobile phones, as well as on routers and mainframes equipped with Java, without any adjustments.

  9. Wildcard (Java) - Wikipedia

    en.wikipedia.org/wiki/Wildcard_(Java)

    Unlike arrays (which are covariant in Java [2]), different instantiations of a generic type are not compatible with each other, not even explicitly. [2] For example, the declarations Generic<Supertype> superGeneric; Generic<Subtype> subGeneric; will cause the compiler to report conversion errors for both castings (Generic<Subtype>)superGeneric and (Generic<Supertype>)subGeneric.
