These are not interpreted by javac directly, but are made available for use by individual processors. Standard Options -A key Options to pass to annotation processors. An additional set of non-standard options are specific to the current virtual machine and compiler implementations and are subject to change in the future. The compiler has a set of standard options that are supported on the current development environment and will be supported in future releases. You can specify a separate destination directory with -d (see Options, below).

For example, if you keep all your source files in C:\workspace, the source code for 圜lass should be in C:\workspace\com\mysoft\mypack\M圜lass.java.īy default, the compiler puts each class file in the same directory as its source file. You should arrange source files in a directory tree that reflects their package tree. These class files have names combining the inner and outer class names, such as M圜lass$MyInnerClass.class.

Inner class definitions produce additional class files. For example, a class called M圜lass would be written in a source file called M圜lass.java and compiled into a bytecode class file called M圜lass.class. class suffixes, and both source and class files must have root names that identify the class. java suffixes, class file names must have. Then use the list file name on the javac command line, preceded by an character. For a large number of source files, list the file names in a file, separated by blanks or line breaks.For a small number of source files, simply list the file names on the command line.There are two ways to pass source code file names to javac: It can also process annotations in Java source files and classes. The javac tool reads class and interface definitions, written in the Java programming language, and compiles them into bytecode class files. The -J options are not allowed in these files. One or more files that lists options and source files. classes One or more classes to be processed for annotations (such as MyPackage.M圜lass). sourcefiles One or more source files to be compiled (such as M圜lass.java).

On Linux\Unix and Mac OS X, typing "locate tools.jar" at a command line can help you locate it. If you cannot find it here, search for "tools.jar" across all your hard drives.
On Windows, it can often be found in "C:\Program Files\Java\Now that the selection dialog is open, navigate through your file system and select your "tools.jar". This will display the same selection dialog. If the dialog is not displayed, select "Edit -> Preferences." and click on the "." to the right of the "tool.jar" field. If the aforementioned "tools.jar" dialog box is displayed, click "Yes" and another dialog will be displayed allowing you to select the location of your "tool.jar" file. In this case, you can tell DrJava where the compiler is.

If you do have a JDK installed, DrJava may be unable to find the compiler.

If you have not yet installed a Java Development Kit (JDK), you can download and install one from (Note: Mac OS X users should already have one installed.)Īfter installing the JDK, DrJava should be able to find and use the newly installed compiler. This usually occurs when the Java compiler is either not installed or installed in a non-standard location. Often, it will display a dialog box indicating that it cannot find "tools.jar". In some cases, DrJava cannot automatically find the Java compiler.
