GRASP (Linux, UNIX) and pcGRASP (Windows) are written in C/C++, whereas jGRASP is written in Java (the "j" in jGRASP means it runs on the JVM). The jGRASP web site offers downloads for Windows, Mac OS, and as a generic ZIP file suitable for Linux and other systems. For languages other than Java and Kotlin, jGRASP is a source code editor and ...
The GNU Compiler for Java (GCJ) is a discontinued free compiler for the Java programming language. It was part of the GNU Compiler Collection. [3] [4] GCJ compiles Java source code to Java virtual machine (JVM) bytecode or to machine code for a number of CPU architectures. It could also compile class files and whole JARs that contain bytecode ...
Classpath is a parameter in the Java Virtual Machine or the Java compiler that specifies the location of user-defined classes and packages. The parameter may be set either on the command-line , or through an environment variable .
Eclipse OpenJ9 (previously known as IBM J9) is a high performance, scalable, Java virtual machine (JVM) implementation that is fully compliant with the Java Virtual Machine Specification. [ 3 ] OpenJ9 can be built from source, or can be used with pre-built binaries available at the IBM Semeru Runtimes project for a number of platforms including ...
GCJ the GCC Java compiler, that compiles either to bytecode or to native machine code. As of GCC 7, gcj and associated libjava runtime library have been removed from GCC. [1] IKVM.NET – Java for Mono and the Microsoft .NET Framework. Uses OpenJDK. Zlib License. JamVM – developed to be an extremely small virtual machine
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.
For example, in the sample build.xml file above, the clean target deletes the classes directory and everything in it. In a Makefile this would typically be done with the command: rm -rf classes/ rm is a Unix-specific command unavailable in some other environments. Microsoft Windows, for example, would use: rmdir /S /Q classes
Hence, developers needed an already-working Java compiler and runtime in order to build OpenJDK. Originally, only the existing proprietary Sun JDK met that requirement. Free distributions like Fedora can't depend on proprietary tools in order to build packages, so the IcedTea project had to make it possible to compile the code using free software.
