gij - GNU interpreter for Java bytecode
gij [OPTION] ... JARFILE [ARGS...] gij [-jar] [OPTION] ... CLASS [ARGS...] [-Dname[=value]...] [-ms=number] [-mx=number] [--showversion] [--version] [--help]
"gij" is a Java bytecode interpreter included with "libgcj". "gij" is not available on every platform; porting it requires a small amount of assembly programming which has not been done for all the targets supported by gcj. The primary argument to "gij" is the name of a class or, with "-jar", a jar file. Options before this argument are interpreted by "gij"; remaining options are passed to the interpreted program. If a class name is specified and this class does not have a "main" method with the appropriate signature (a "static void" method with a "String[]" as its sole argument), then "gij" will print an error and exit. If a jar file is specified then "gij" will use information in it to determine which class' "main" method will be invoked. "gij" will invoke the "main" method with all the remaining command-line options. Note that "gij" is not limited to interpreting code. Because "libgcj" includes a class loader which can dynamically load shared objects, it is possible to give "gij" the name of a class which has been compiled and put into a shared library on the class path.
-Dname[=value] This defines a system property named name with value value. If value is not specified then it defaults to the empty string. These system properties are initialized at the program's startup and can be retrieved at runtime using the "java.lang.System.getProperty" method. -ms=number This sets the initial heap size. -mx=number This sets the maximum heap size. -jar This indicates that the name passed to "gij" should be interpreted as the name of a jar file, not a class. --help Print help, then exit. --showversion Print version number and continue. --version Print version number, then exit.
