@Subz is it possible to download from internet java. in script check if exist java in PC do nothing, if no download from internet and install it

You could but not recommended unless you know a direct path to the download and these urls can change.  If you're packaging an application in-house you should always supply the third-party software with the package, otherwise your users are all downloading software when they could just use your version from a server share.  If you were packaging an application for external product then you would normally just tell the end user to download the latest Java runtime unless your application requires a specific version in which case you would supply that version with your application.  You may need to check the third-party license on packaging there apps, I know Adobe requires you to request this type of license.
