Utilities are programs that can run or execute. Commands are slightly different than utilities. Command refers to the name of the program and any arguments you specify to that program to change its behavior.
Unix is an operating system, Java is a language.

They both are frequently used programs in UNIX, but they do different things. Read their manuals if you want to use them.
Traditionally, the UNIX command interface was the only way to communicate within a UNIX system. Today, that is not true, with the graphical interfaces that are available. However, the true power of what you can do within UNIX is still in the command line interface. The command line interface is not very intuitive, and uses commands that are abbreviated to the point of not necessarily being understandable. Also, system administration tasks in Unix have typically been harder to accomplish because of the amount of background knowledge necessary even to do simple things. UNIX was developed early on for programmers by programmers, and little thought was given to the end user; as a result, it had a reputation of being difficult to use until you took the time to understand the (admittedly) arcane command line interface.

A command is something that's built-in to the kernel, where as the utility is something that runs on top of the kernel. Example of utilities are: fdisk, copy, edit, etc.
They are different languages, so you need to use a different word with different syntax to do the same thing. For example, to display the contents of the current directory, the command in MS-DOS is dir, but in UNIX it's ls.
Command set and command switches. Both are based on the UNIX operating system, so they have the core of the operating system in common.
su substitute user.. and su is a unix command used to run the shell of another user without logging off..
No difference, really. Unix is an OS (Operating System)
what are similarities and differences between linux and unix?
There is no traditional 'execute' command in Unix.
UNIX is a command-based OS. In contrast, Windows is a menu-based OS.
There is no standard 'format' command in Unix.
Unix is an operating system, Java is a language.
The 'CD' command is not standard for Unix. The 'cd' command, however, will change directories (folders). It is a means of navigating the Unix file system.
