If you are cross-compiling (compiling classes against bootstrap and extension classes of a different Java platform implementation), this option specifies the directories that contain the extension classes. All JAR archives found are automatically part of the class path.

Each JAR archive in the specified directories is searched for class files. The directories variable is a colon-separated list of directories. extdirs directories Overrides the location of the ext directory. endorseddirs directories Override the location of endorsed standards path. If -encoding is not specified, the platform default converter is used. encoding encoding Set the source file encoding name, such as EUC-JP and UTF-8. deprecation is shorthand for -Xlint:deprecation. Without -deprecation, javac shows a summary of the source files that use or override deprecated members or classes. deprecation Show a description of each use or override of a deprecated member or class. Note: The directory specified by -d is not automatically added to your user class path. If -d is not specified, javac puts each class files in the same directory as the source file from which it was generated. For example, if you specify -d C:\myclasses and the class is called 圜lass, then the class file is called C:\myclasses\com\mypackage\M圜lass.class. If a class is part of a package, javac puts the class file in a subdirectory reflecting the package name, creating directories as needed. The directory must already exist javac will not create it. d directory Set the destination directory for class files. = directories Override the location of endorsed standards path. = directories Override the location of installed extensions. If the -processorpath option is not specified, the class path is also searched for annotation processors. If the -sourcepath option is not specified, the user class path is also searched for source files. See Setting the Class Path for more details. If neither CLASSPATH, -cp nor -classpath is specified, the user class path consists of the current directory. This class path overrides the user class path in the CLASSPATH environment variable. cp path or -classpath path Specify where to find user class files, and (optionally) annotation processors and source files. key should be one or more identifiers separated by ".". 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.
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).
