2. Java (software platform) - Wikipedia

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

   The Java platform is a suite of programs that facilitate developing and running programs written in the Java programming language. A Java platform includes an execution engine (called a virtual machine), a compiler and a set of libraries; there may also be additional servers and alternative libraries that depend on the requirements.

3. Java performance - Wikipedia

   en.wikipedia.org/wiki/Java_performance

   The target platform of Java's bytecode compiler is the Java platform, and the bytecode is either interpreted or compiled into machine code by the JVM. Other compilers almost always target a specific hardware and software platform, producing machine code that will stay virtually unchanged during execution [ citation needed ] .

4. Java virtual machine - Wikipedia

   en.wikipedia.org/wiki/Java_virtual_machine

   When Java bytecode is executed by an interpreter, the execution will always be slower than the execution of the same program compiled into native machine language. This problem is mitigated by just-in-time (JIT) compilers for executing Java bytecode. A JIT compiler may translate Java bytecode into native machine language while executing the ...

5. Compiler - Wikipedia

   en.wikipedia.org/wiki/Compiler

   Compiler technology evolved from the need for a strictly defined transformation of the high-level source program into a low-level target program for the digital computer. The compiler could be viewed as a front end to deal with the analysis of the source code and a back end to synthesize the analysis into the target code.

6. List of compilers - Wikipedia

   en.wikipedia.org/wiki/List_of_compilers

   Edison Design Group: provides production-quality front end compilers for C, C++, and Java (a number of the compilers listed on this page use front end source code from Edison Design Group [110]). Additionally, Edison Design Group makes their proprietary software available for research uses. [111]

7. HotSpot (virtual machine) - Wikipedia

   en.wikipedia.org/wiki/HotSpot_(virtual_machine)

   Tiered compiling, an option introduced in Java 7, uses both the client and server compilers in tandem to provide faster startup time than the server compiler, but similar or better peak performance. [9] Starting in Java 8, tiered compilation is the default for the server VM. [10] HotSpot is written in C++ and Assembly.

8. History of compiler construction - Wikipedia

   en.wikipedia.org/wiki/History_of_compiler...

   In computing, a compiler is a computer program that transforms source code written in a programming language or computer language (the source language), into another computer language (the target language, often having a binary form known as object code or machine code).

9. Java bytecode - Wikipedia

   en.wikipedia.org/wiki/Java_bytecode

   GNU Compiler for Java (GCJ), compiles from Java to Java bytecode; it can also compile to native machine code and was part of the GNU Compiler Collection (GCC) up until version 6. Some projects provide Java assemblers to enable writing Java bytecode by hand. Assembly code may be also generated by machine, for example by a compiler targeting a ...
