With one argument ending in ".", the switch enables assertions in the specified package and any subpackages. With no arguments, -enableassertions or -ea enables assertions. The -disablesystemassertions option provides a separate swith to enable assertions in all system classes. This makes it easy to turn on asserts in all classes except for system classes. There is one exception to this rule: in their no-argument form, the switches do not apply to system. The -disableassertions and -da switches apply to all class loaders and to system classes (which do not have a class loader). To run a program with assertions enabled in package but disabled in class, the following command could be used: With one argument not ending in ".", the switch disables assertions in the specified class. If the argument is ".", then the switch disables assertions in the unnamed package in the current working directory. With one argument ending in ".", the switch disables assertions in the specified package and any subpackages. With no arguments, -disableassertions or -da disables assertions. This is subject to change in a future release. The -client option is ignored with the use of -d64.
By default, the application is run in a 32-bit environment unless a 64-bit only system is used.Ĭurrently only the Java HotSpot Server VM supports 64-bit operation, and the -server option is implicit with the use of -d64. If a 64-bit environment is not installed or is not supported, an error will be reported. Run the application in a 64-bit environment. By default, the application is run in a 32-bit environment unless a 64-bit only system is used. If a 32-bit environment is not installed or is not supported, an error will be reported. Run the application in a 32-bit environment. For example, by calling System.getenv("CLASSPATH"). No Java program will ever see wild cards that are not expanded except by querying the environment. Any class path wildcard expansion occurs before the Java VM is started. The CLASSPATH environment variable, where defined, will be similarly expanded. A class path entry consisting simply of * expands to a list of all the jar files in the current directory. All jar files in the specified directory, even hidden ones, are included in the list. A Java program cannot tell the difference between the two invocations.įor example, if directory mydir contains a.jar and b.JAR, then the class path element mydir/* is expanded to a A.jar:b.JAR, except that the order of jar files is unspecified.
If -classpath and -cp are not used and CLASSPATH is not set, then the user class path consists of the current directory (.).Īs a special convenience, a class path element that contains a base name of * is considered equivalent to specifying a list of all the files in the directory with the extension. Specifying -classpath or -cp overrides any setting of the CLASSPATH environment variable. Separate class path entries with colons (:).

Loads a native agent library by full pathname. See JVMTI Agent Command-Line Options at -agentpath: pathname Loads native agent library libname, for example: On a 64-bit capable JDK, only the Java Hotspot Server VM is supported so the - server option is implicit.įor default a Java VM selection, see the Server-Class Machine Detection page at -agentlib: libname A 64-bit capable JDK currently ignores this option and instead uses the Java Hotspot Server VM.įor default Java VM selection, see the Server-Class Machine Detection page at -server
In addition, the current implementations of the virtual machines support a set of nonstandard options that are subject to change in future releases. The launcher has a set of standard options that are supported in the current runtime environment. Non-option arguments after the class name or JAR file name are passed to the main function. The Java runtime searches for the startup class, and other classes used, in three sets of locations: the bootstrap class path, the installed extensions, and the user class path. If the -jar option is specified, then the first non-option argument is the name of a JAR file containing class and resource files for the application, with the startup class indicated by the Main-Class manifest header. A fully qualified class name should be used. The method declaration has the following form:īy default, the first argument without an option is the name of the class to be called. The method must be declared public and static, it must not return any value, and it must accept a String array as a parameter. It does this by starting a Java runtime environment, loading a specified class, and calling that class's main method. The java command starts a Java application. The arguments passed to the main function.
