Select the Environment Variables button. You will see two sections: 'User variables for YourName' and 'System variables'. If you add it to the 'User variables' section, the PATH variable will be in effect only when you are logged on.
If you add it to the 'System variables' section, it will be in effect as long as someone is logged on. If you are not sharing the machine with anyone else who writes Java programs, you may add it to either section. Capitalization of the name does NOT matter.

Company Questions. Artificial Intelligence. Run the EXE you get to install it. We will use it in a moment to install the documentation. It will unpack and install the development kit automatically. Read the installation instructions for the documentation. They will instruct you to move the documentation file to same directory as that containing the development kit you just installed.
Unzip the documentation and it will drop into the proper place. As instructed on this page , you need to change your path variable. Then open autoexec. If everything is set up properly, then you should see a two-line blob of text come out that tells you how to use javac. That means you are ready to go. If you see the message "Bad Command or File Name" it means you are not ready to go.
Figure out what you did wrong by rereading the installation instructions. The -J options are not supported because they are passed to the launcher, which does not support argument files. When executing javac, pass in the path and name of each argument file with the ' ' leading character.
You can create two argument files -- one for the javac options and the other for the source filenames: Notice the following lists have no line-continuation characters. The argument files can have paths, but any filenames inside the files are relative to the current working directory not path1 or path2 :. The API for annotation processors is defined in the javax.
Unless annotation processing is disabled with the -proc:none option, the compiler searches for any annotation processors that are available. The search path can be specified with the -processorpath option; if it is not given, the user class path is used. Processor on the search path. Such files should contain the names of any annotation processors to be used, listed one per line.
Alternatively, processors can be specified explicitly, using the -processor option. After scanning the source files and classes on the command line to determine what annotations are present, the compiler queries the processors to determine what annotations they process.
When a match is found, the processor will be invoked. A processor may "claim" the annotations it processes, in which case no further attempt is made to find any processors for those annotations.
Once all annotations have been claimed, the compiler does not look for additional processors. If any processors generate any new source files, another round of annotation processing will occur: any newly generated source files will be scanned, and the annotations processed as before. Any processors invoked on previous rounds will also be invoked on all subsequent rounds. This continues until no new source files are generated. After a round occurs where no new source files are generated, the annotation processors will be invoked one last time, to give them a chance to complete any work they may need to do.
Finally, unless the -proc:only option is used, the compiler will compile the original and all the generated source files. To compile a set of source files, the compiler may need to implicitly load additional source files. Such files are currently not subject to annotation processing. By default, the compiler will give a warning if annotation processing has occurred and any implicitly loaded source files are compiled. See the -implicit option for ways to suppress the warning.
When compiling a source file, the compiler often needs information about a type whose definition did not appear in the source files given on the command line.
The compiler needs type information for every class or interface used, extended, or implemented in the source file. This includes classes and interfaces not explicitly mentioned in the source file but which provide information through inheritance.
For example, when you subclass java. Applet , you are also using Applet's ancestor classes: java. Panel , java. Container , java. Component , and java.
When the compiler needs type information, it looks for a source file or class file which defines the type. The compiler searches for class files first in the bootstrap and extension classes, then in the user class path which by default is the current directory. For details, see Setting the Class Path. If you set the -sourcepath option, the compiler searches the indicated path for source files; otherwise the compiler searches the user class path for both class files and source files.
