  2. Java performance - Wikipedia

    In November 2004, Nailgun, a "client, protocol, and server for running Java programs from the command line without incurring the JVM startup overhead" was publicly released. [59] introducing for the first time an option for scripts to use a JVM as a daemon, for running one or more Java applications with no JVM startup overhead. The Nailgun ...

  3. Java concurrency - Wikipedia

    en.wikipedia.org/wiki/Java_concurrency

    Each thread can be scheduled [5] on a different CPU core [6] or use time-slicing on a single hardware processor, or time-slicing on many hardware processors. There is no general solution to how Java threads are mapped to native OS threads. Every JVM implementation can do this differently. Each thread is associated with an instance of the class ...

    en.wikipedia.org/wiki/Multithreading_(computer...

    Only when the data for the previous thread had arrived, would the previous thread be placed back on the list of ready-to-run threads. For example: Cycle i: instruction j from thread A is issued. Cycle i + 1: instruction j + 1 from thread A is issued. Cycle i + 2: instruction j + 2 from thread A is issued, which is a load instruction that misses ...

    Java: the JVMTI (JVM Tools Interface) API, formerly JVMPI (JVM Profiling Interface), provides hooks to profilers, for trapping events like calls, class-load, unload, thread enter leave. .NET : Can attach a profiling agent as a COM server to the CLR using Profiling API .

    C# standard library does not have classes to deal with arbitrary-precision floating point numbers (see software for arbitrary-precision arithmetic). C# can help mathematical applications with the checked and unchecked operators that allow the enabling or disabling of run-time checking for arithmetic overflow for a region of code.

  7. Java virtual machine - Wikipedia

    en.wikipedia.org/wiki/Java_virtual_machine

    Code, constants, and other class data are stored in the "method area". The method area is logically part of the heap, but implementations may treat the method area separately from the heap, and for example might not garbage collect it. Each JVM thread also has its own call stack (called a "Java Virtual Machine stack" for clarity), which stores ...

  8. Java Native Interface - Wikipedia

    en.wikipedia.org/wiki/Java_Native_Interface

    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.

  9. Comparison of Java and C++ - Wikipedia

    en.wikipedia.org/wiki/Comparison_of_Java_and_C++

    In Java, low level errors either cannot occur or are detected by the Java virtual machine (JVM) and reported to the application in the form of an exception. The Java language requires specific behavior in the case of an out-of-bounds array access, which generally requires bounds checking of array accesses.
