 ******************************************************************************

a - Download and install (FREE) virtualbox in your laptop from:
    https://www.virtualbox.org/

    If your computer is a MAC Computer, depending on your OS Version,
    virtualBox might not work in your Mac, therefore you will have to
    install the Mac VM named Parallels

 
b - From inside your VM (Virtual Machine), download ubuntu 16.04 Operating System ISO
    for AMD or Intel cpus at:
    https://users.cs.fiu.edu/~mrobi002/linux-iso/

    where you will find:
    
    ubuntu-20.04.4-desktop_amd64.iso  for 64 bit computers
  
    or
    
    Download and install Ubuntu version 16.04 as a virtual OS inside your VM, from
    https://www.ubuntu.com/download/alternative-downloads

  
c - From inside your VM (Virtual Machine) in Terminal Mode, download and install
    Java JDK inside your Ubuntu Virtual Machine as follows:

    sudo apt update

    sudo apt install default-jdk


d - From inside your Ubuntu terminal mode
    run the following commands:
    java -version
    javac -version
 
    Make sure that your "java -version" and your "javac -version" are the same version 


e - Make sure that your java programs can compiled and run in terminal mode in all Vms.
    WITHOUT getting ANY WARNINGS.

    
f - *** USING TERMINAL MODE ONLY ***, and using my JAVA Programming Rules, located at:      

    https://users.cs.fiu.edu/~mrobi002/includes/JAVA_programmingRules      

    NOTE: During the entire semester, in this class, when using Java, we will
          ONLY use the System.out printf(...) command

          In all Java program we will use 4(four) SPACES ***NO TABS***
          when indenting.

          PLEASE AVOID LOSING POINTS IN YOUR PROGRAMS


    do the following:
    

g - *** USING TERMINAL MODE ONLY ***
    In your Ubuntu Virtual Machine (VM) do the following:

    1) Create a folder called pgm1
       ***WARNING***
       I AM NOT ASKING YOU TO GO TO YOUR DESKTOP, HOME, USER, ETC DIRECTORY

       Just when you log into your Ubuntu terminal mode create a folder named pgm1

       When I grade your program I will execute it from my local ubuntu folder

       If your program is trying to execute from any other folder you will get
       a 0 (zero) grade 
    
    2) Move into the pgm1 folder
    
    3) Using a linux editor ONLY, create a Java program named:
       your last name + first letter of your first name + ubuntuPgm1.java
       
       example robinsonMubuntuPgm1.java

       At the top/beginning of the this program, totally aligned to the left,
       place the following documentation:
