sorry for that, but I'm running out of time and I don't want that my app goes offline.You shouldn't have made three duplicate posts for this.
Lets start with Java. You do not need to install Java. Only to extract the files. You need to download the Java tar file (for linux) to your PC: https://java.com/en/download/manual.jsp
Upload it to your linux and extract it.
