Corrected the mistake mentioned by the prof on MyCourses
Removed Unused argument WW

WW is not used anywhere in the code, and is therefore unnecessary.
CC -> numberOfColumns

CC represents the number of columns that the prime numbers should be
printed in, therefore I renamed it to something more clear.
RR -> numberOfRows

RR represents the number of rows that the prime numbers should print in.
Therefore I renamed it to a variable name that was clearer.
JPRIME -> isPrime

The boolean JPRIME was to know if a certain number was prime or not.
Therefore, it was renamed to something more clear.
J -> currentNumber

J represented the number we were currently checking, therefore it was
renamed to something more clear.
SQUARE -> square

Now respects variable naming guidelines.
PAGENUMBER -> pageNumber, PAGEOFFSET -> pageOffset, ROWOFFSET -> rowOffset

Renamed some variables to respect variable naming guidelines.
Added Brackets Around Single-Line if Statements

Easier to read.
ORD -> primeNumberIndex

Added a comment explaining the use of this variable in the code as well.
N -> i, moved variable declaration closer to its use

N here is just an index for the MULT arraylist, therefore it was renamed
to a more conventional index name.
The variable is only used in a part of the code, therefore its
declaration was moved to this part.
MULT -> nonPrimeNumbers

MULT was an arraylist that stored non prime numbers that we compared to
the current number. Therefore it was renamed accordingly.
ORDMAX -> nonPrimeNumbersArraySize

ORDMAX dictated the size of the nonPrimeNumbersArray
Fixed Entire Code Indentation
Brackets Around 1-Line While Statement
C -> currentColumn

More descriptive variable name
Added Spaces to make Code More Legible
Commented the code
Added method descriptions
