The directory must already exist because javac does not create it. Sets the destination directory for class files.

Overrides the location of the endorsed standards path. Overrides the location of installed extensions. If the -processorpath option is not specified, then the class path is also searched for annotation processors. If the -sourcepath option is not specified, then the user class path is also searched for source files. If neither CLASSPATH, -cp nor -classpath is specified, then the user class path is the current directory. This class path overrides the user class path in the CLASSPATH environment variable. Specifies where to find user class files, and (optionally) annotation processors and source files. The key value should be one or more identifiers separated by a dot (.). These options are not interpreted by javac directly, but are made available for use by individual processors.

Specifies options to pass to annotation processors. You can specify a separate destination directory with the -d option. For example, if all of your source files are in \workspace, then put the source code for 圜lass in /workspace in \ workspace\com\mysoft\mypack\M圜lass.java.īy default, the compiler puts each class file in the same directory as its source file. These class files have names that combine the inner and outer class names, such as M圜lass$MyInnerClass.class.Īrrange source files in a directory tree that reflects their package tree. 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.

Use the list file name preceded by an at sign with the javac command. There are two ways to pass source code file names to javac.įor a small number of source files, list the file names on the command line.įor a large number of source files, list the file names in a file that is separated by blanks or line breaks. The javac command can also process annotations in Java source files and classes. The javac command reads class and interface definitions, written in the Java programming language, and compiles them into bytecode class files.
