Go to the path where you saved the java file you want to compile.
Replace path by typing cmd and press enter.
Command Prompt Directory will pop up containing the path file like C:/blah/blah/foldercontainJava.
Enter javac javafile.java.
Press Enter. It will automatically generate java class file.

Yes, as long as you have Java installed you will be able to run it on a computer running UNIX.
The whole idea of Java - one of the ideas - is to be able to run on multiple platforms.
Unix is an operating system, Java is a language.
You look at the file. A program such as Windows Explorer - or the equivalent in other operating systems - can tell you the size. Also, a command such as "dir" (in Windows), or "ls" (in Linux or Unix).

UNIX is an open source operating system. As natural for an OS, it has its own way of doing all the tasks it is supposed to do- like managing files, allocating resources, handling user accounts- so on and so forth. These features make working on UNIX a different experience to working on Windows or Mac OSx- just like the experience of Windows is dissimilar to the OSx experience. Keeping this in mind, the platform and the tools UNIX offers is collectively known as the UNIX environment.
Java was developed to be run on any OS. The existence of the Java Virtual Machine means that only the JVM has to be ported to different platforms, so Java source code can be run on any of those platforms without any change.(If the question was asking what system Java was developed on, then I don't know for sure. But since it was developed at Sun Microsystems, one could safely assume it was written in some version of Solaris.)
Unix is an operating system, Java is a language.
There is no the system file. There are many files necessary to create a working Unix system.
Unix files can be easily transferred to windows via a network connection either by using FTP or by using Samba. Samba allows a Unix file system to be mounted/shared on a Windows system to look like a windows directory.

For Unix systems that are only talking to other Unix systems NFS (Network File System) is the most popular. If you want to share Unix files with Windows systems, then Samba is one of the most popular ways to accomplish this.
Unix-like operating systems are used to save files on a computer operating system. When using this type of system, to unlink a file means to erase or delete it.
AnswerRecovering any 'deleted' and/or 'overwritten' file in a typical Unix system is problematic and much more difficult to do reliably than it is with, say, a typical Windows system. This is a function of the way the files are stored on a Unix system, not a problem with, or feature of, the operating system itself. I suggest you obtain and study Wietse Venema's TCT (The Coroner's Toolkit) for further information. [JMH]
This is not really a good comparison. It's like asking if a telephone is better than a TV. OK, well Android is an operating system, based on Linux (similar to Unix). Java is a programming language - a set of rules that programmers use to create the programs (apps). The operating system controls the basic functions and how the phone (or tablet) interacts with files and the user.
Privileges, in regards to computer science terms, are permissions granted by a system to allow certain data or files to be accessed or used. In UNIX, all files and data are assigned a set of permissions by the system. The files or data can be read, modified, and executed depending on the set of permissions assigned to the user.
Unix work is performed by users of the unix system, for application and system programs, or anything that requires a Unix system.
Being the well known entity files are, files are also called "regular files" to distinguish them from "special files". They show up in ls -l without a specific character in the mode field:
It's where all settings, documents, private files, etc. are located.
