Since version 0.95, GNU Classpath, a free implementation of the Java Class Library, supports compiling and running javac using the Classpath runtime — GNU Interpreter for Java (GIJ) — and compiler — GNU Compiler for Java (GCJ) — and also allows one to compile the GNU Classpath class library, tools and examples with javac itself. [6]
The user cannot replace this class name using the invocation java -jar. Class-Path describes the location of supportLib.jar relative to the location of the library helloWorld.jar. Neither absolute file path, which is permitted in -classpath parameter on the command line, nor jar
In the case of GCJ, it uses ecj to perform this initial stage, then converts the bytecode to native code. From 0.95 onwards, GNU Classpath also supports compiling and running the newly GPLed open-source javac compiler using GNU Classpath and also allows the GNU Classpath class library, tools and examples to be compiled with javac itself.
Originally only one compiler existed, the javac compiler from Sun Microsystems, which compiles Java source code to Java bytecode; but because all the specifications for Java bytecode are now available, other parties have supplied compilers that produce Java bytecode. Examples of other compilers include: Eclipse compiler for Java (ECJ)
The most important type of object contained in a Jar file is a Java class. A class can be thought of as a named unit of code. A class can be thought of as a named unit of code. The class loader is responsible for locating libraries, reading their contents, and loading the classes contained within the libraries.
idlj – the IDL-to-Java compiler. This utility generates Java bindings from a given Java IDL file. jabswitch – the Java Access Bridge. Exposes assistive technologies on Microsoft Windows systems. java – the loader for Java applications. This tool is an interpreter and can interpret the class files generated by the javac compiler.

For example, to build the compile target Ant must first create a directory called classes (which Ant will do only if it does not already exist) and then invoke the Java compiler. Therefore, the tasks used are mkdir and javac. These perform a similar task to the command-line utilities of the same name. Another task used in this example is named jar:
