12 System properties

The runtime behavior of the libgcj library can be modified by setting certain system properties. These properties can be compiled into the program using the -Dname[=value] option to gcj or by setting them explicitly in the program by calling the java.lang.System.setProperty() method. Some system properties are only used for informational purposes (like giving a version number or a user name). A program can inspect the current value of a property by calling the java.lang.System.getProperty() method.

• Standard Properties: Standard properties supported by libgcj
