Next in the Series: Javap – the Disassembler. You can use the foundation JDK tools and commands to create and build applications.

The following sections describe the tools and commands that you can use to create and build applications:. The javac command reads class and interface definitions, written in the Java programming language, and compiles them into bytecode class files.

The javac command can also process annotations in Java source files and classes. For a few source files, you can use the filename option on the javac command line to include a file that lists the source file names. Source code file names must have. For example, a class called MyClass would be written in a source file called MyClass.

Inner class definitions produce additional class files. You should arrange the source files in a directory tree that reflects their package tree. For example:. By default, the compiler puts each class file in the same directory as its source file. You can specify a separate destination directory with the -d option described in Standard Options. The javac command supports the new Java Compiler API defined by the classes and interfaces in the javax. To compile a set of source files, the compiler might need to implicitly load additional source files.

Such files are currently not subject to annotation processing. By default, the compiler gives a warning when annotation processing occurs and any implicitly loaded source files are compiled.

The -implicit option provides a way to suppress the warning. The encoding requirement for the environment variable is the same as the javac command line on the system.

Single quotes ‘ or double quotes ” can be used to enclose arguments that contain whitespace characters. All content between the open quote and the first matching close quote are preserved by simply removing the pair of quotes. In case a matching quote is not found, the launcher will abort with an error message. However, as in files , use of a wildcard is not supported:. The compiler has sets of standard options, and cross-compilation options that are supported on the current development environment.

The compiler also has a set of nonstandard options that are specific to the current virtual machine and compiler implementations but are subject to change in the future. The nonstandard options begin with -X. The different sets of javac options are described in the following sections:. To shorten or simplify the javac command, you can specify one or more files that contain arguments to the javac command except -J options. This lets you to create javac commands of any length on any operating system.

These options are not interpreted by javac directly, but are made available for use by individual processors. The key value should be one or more identifiers separated by a dot.

If a class is part of a package, then javac puts the class file in a subdirectory that reflects the package name and creates directories as needed.

Without the -deprecation option, javac shows a summary of the source files that use or override deprecated members or classes. The -deprecation option is shorthand for -Xlint:deprecation. Used in conjunction with either -source or –release. The directories variable is a colon-separated list of directories.

Each JAR file in the specified directories is searched for class files. All JAR files found become part of the class path. By default, only line number and source file information is generated. Valid keywords are:. When you specify this option, a native header file is generated for each class that contains native methods or that has one or more constants annotated with the java.

Native annotation. If the class is part of a package, then the compiler puts the native header file in a subdirectory that reflects the package name and creates directories as needed. In this case, the compiler issues a warning if any class files are generated when also doing annotation processing.

See Searching for Types. For example, -J-Xms48m sets the startup memory to 48 MB. This option operates the same as the -Xlint:none option.

Stores formal parameter names of constructors and methods in the generated class file so that the method java. This bypasses the default discovery process. Specifies the directory used to place the generated source files. If a class is part of a package, then the compiler puts the source file in a subdirectory that reflects the package name and creates directories as needed. The following values for release are allowed:. The compiler accepts code with features introduced in Java SE This is the source code path used to search for class or interface definitions.

As with the user class path, source path entries are separated by colons : on Linux and macOS and semicolons ; on Windows. If packages are used, then the local path name within the directory or archive must reflect the package name.

Messages include information about each class loaded and each source file compiled. By default, for releases prior to JDK 9, classes were compiled against the bootstrap classes of the platform that shipped with thejavac command. But javac also supports cross-compiling, in which classes are compiled against bootstrap classes of a different Java platform implementation.

It can have one of the following values in order of most to least visible :. For more information about these groups of checks, see the -Xdoclint option of the javadoc command. The -Xdoclint option is disabled by default in the javac command.

For example, the following option checks classes and members with all groups of checks that have the access level of protected and higher which includes protected and public :. Each package is either the qualified name of a package or a package name prefix followed by a period and asterisk. Each package can be prefixed with a hyphen – to disable checks for a specified package or packages.

In this release, enabling all available warnings is recommended. Precede a key by a hyphen – to disable the specified warning. This does not perform annotation processing or compilation.

The format of the output could change. By default, compiler messages go to System. An argument file can include javac options and source file names in any combination.

The arguments within a file can be separated by spaces or new line characters. If a file name contains embedded spaces, then put the whole file name in double quotation marks. File names within an argument file are relative to the current directory, not to the location of the argument file.

When executing the javac command, pass in the path and name of each argument file with the at sign leading character. When the javac command encounters an argument beginning with the at sign , it expands the contents of that file into the argument list.

Single Argument File You could use a single argument file named argfile to hold all javac arguments:. This argument file could contain the contents of both files shown in the following Two Argument Files example. Two Argument Files You can create two argument files: one for the javac options, and the other for the source file names. Note that the following lists have no line-continuation characters.

Create a file named options that contains the following:. Argument Files with Paths The argument files can have paths, but any file names inside the files are relative to the current working directory not path1 or path2 :.

If the -Xlint:fallthrough option was used when compiling this code, then the compiler emits a warning about possible fall-through into case, with the line number of the case in question.

The compiler generates a warning for the finally block in this example. When the int method is called, it returns a value of 0. A finally block executes when the try block exits.

In this example, when control is transferred to the catch block, the int method exits. See Cross-Compilation Options for javac. For example, consider the following two classes:.

When the compiler encounters a varargs method, it translates the varargs formal parameter into an array. In the method ClassWithVarargsMethod. Consequently, this example compiles. For example, the following is a simple annotation processor:. The following commands compile the annotation processor AnnoProc , then run this annotation processor against the source file AnnosWithoutProcessors.

When the compiler runs the annotation processor against the source file AnnosWithoutProcessors. To resolve this issue, you can rename the annotation defined and used in the class AnnosWithoutProcessors from Anno to NotAnno. The following statement generates a rawtypes warning:. List is a raw type. Because List is a parameterized interface, always specify its type argument.
