  2. Java performance - Wikipedia

    en.wikipedia.org/wiki/Java_performance

    Results for microbenchmarks between Java and C++ highly depend on which operations are compared. For example, when comparing with Java 5.0: 32- and 64-bit arithmetic operations, [48] [49] file input/output, [50] and exception handling [51] have a similar performance to comparable C++ programs; Operations on arrays [52] have better performance in C.

    The Computer Language Benchmarks Game site warns against over-generalizing from benchmark data, but contains a large number of micro-benchmarks of reader-contributed code snippets, with an interface that generates various charts and tables comparing specific programming languages and types of tests.

  4. Java (programming language) - Wikipedia

    en.wikipedia.org/wiki/Java_(programming_language)

    Java is a high-level, class-based, object-oriented programming language that is designed to have as few implementation dependencies as possible. It is a general-purpose programming language intended to let programmers write once, run anywhere (), [16] meaning that compiled Java code can run on all platforms that support Java without the need to recompile. [17]

    en.wikipedia.org/wiki/Ahead-of-time_compilation

    In computer science, ahead-of-time compilation (AOT compilation) is the act of compiling an (often) higher-level programming language into an (often) lower-level language before execution of a program, usually at build-time, to reduce the amount of work needed to be performed at run time.

    In 1989, C++ 2.0 was released, followed by the updated second edition of The C++ Programming Language in 1991. [32] New features in 2.0 included multiple inheritance, abstract classes, static member functions, const member functions, and protected members. In 1990, The Annotated C++ Reference Manual was published. This work became the basis for ...

  9. Class (computer programming) - Wikipedia

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

    A class consisting of only pure virtual methods is called a pure abstract base class (or pure ABC) in C++ and is also known as an interface by users of the language. [13] Other languages, notably Java and C#, support a variant of abstract classes called an interface via a keyword in the language.
