Part 1 - Java program named MemoryCalculator - Worth 5 points

    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, build 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

 

    *** BUILD 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 - Worth 5 points.

  - NOT using editors, build 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
