Java program named MemoryCalculator

Part 1 - Java program named MemoryCalculator
     In your Ubuntu VM (virtual machine), using terminal mode ONLY, do the following:
     
     Create the folder program2
     
     In this folder place the text file located on my faculty website in Module 2 called RAMerrors (Do not rename this file, it has no extension.)
     
     Each record in this file represents the location of an error found in RAM
     
     Assume you have a computer with 4 gigs of RAM, each gig in a 
     different memory chip, therefore you have 4 one gig RAM chips.

                                         ---------decimal---------------   
     HINT: RAM chip 0 contain addresses:              0 -  8,589,934,584 bits
           RAM chip 1 contain addresses:  8,589,934,585 - 17,179,869,184 bits
           RAM chip 2 contain addresses: 17,179,869,185 - 25,769,803,768 bits
           RAM chip 3 contain addresses: 25,769,803,769 - 34,359,738,368 bits
           
           
     HINT: RAM chip 0 contain addresses:             0 -  1,073,741,823 bytes
           RAM chip 1 contain addresses: 1,073,741,824 -  2,147,483,648 bytes 
           RAM chip 2 contain addresses: 2,147,483,647 -  3,221,225,471 bytes 
           RAM chip 3 contain addresses: 3,221,225,472 -  4,294,967,296 bytes 

                                
     In the same folder, in terminal mode using an editor, create a Java program 
     to do the following:
     - Call the Java program - MemoryCalculator
     - Open the RAMerrors text file  
     - Read each record
     - Print the RAM memory chip where the error is located for each record
 
     *** CREATE YOUR OWN METHODS THAT WILL CONVERT 
           HEX TO BINARY AND BINARY TO DECIMAL

     *** DO NOT USE JAVA'S AUTOMATIC CONVERSION METHODS 
 
 
 Part 2 - Linux Shell Scripting
   - NOT using editors, create a sh file named: program2.sh
    - Set this *.sh file to: chmod 755 *.sh
    - NOT using editors, append your name, current date and time to a NEW file called results.txt
    - NOT using editors, append to the *.sh file, all the commands needed so that when you execute your sh file,
     this file will produce the following:
     
   How: 
   - Ask the user to enter a number.
   - Verify that the number is between 1 and 100.
   - If the number is not between 1 and 100, then keep asking the user to enter a number until it is valid.
   - Use a for loop from 1 to the value entered by the user 
   - Sum the results of calculating each number mod 5
   - After the for loop ends, display the sum of all previous results and
     append it to the results.txt file as follows 
     Sum of numbers is xxx
