Hi!

Itt a válasz, bocsi, hogy angolul:

Setting up the path
Windows 2000/XP users may set their path by right-clicking on 'My Computer' and selecting
'Properties'. Under the 'Advanced' tab, there is a button that allows you to set the 'Environment
variables'. Click on this and alter the 'Path' variable so that it also contains the path to the
Java executable. For example, if you have installed Java in c:\jdk and your path is currently set
to C:\WINDOWS\SYSTEM32, then you would change your path to read C:\WINDOWS\SYSTEM32;c:\jdk\bin
When you open a new command prompt, it will reflect these changes and allow you to run java
programs by typing ''java''. If you have installed the SDK, then you will also be able to run
''javac'' to compile stuff. Windows 95/98/ME users may find that their path variable is stored in
a different place. Edit the c:\autoexec.bat file and add the following line at the end:
SET PATH=%PATH%;c:\jdk\bin
(This also assumes that you have installed Java in c:\jdk)
Linux, UNIX, Solaris, FreeBSD users must set their PATH variable to point to where the java
binaries have been installed. Please refer to your shell documentation if you have trouble
doing this. For example, if you use bash as your shell, then you would add the following line to
the end of your .bashrc: export PATH=/path/to/java:$PATH
