Arrays

This past week, we learned about arrays. The concepts were new, but not too daunting. The week went by a little better than the previous ones because I was able to fix the GCD lab for my group. Apparently, || and && can make all the difference in the world when completing a code!
This is a segment of our code from the lab:

public int findGCD()
   {
      int gcd = numerator;
     
         if(numerator > denominator)
         {
            gcd = denominator;
           
            while(numerator%gcd != 0 || denominator%gcd != 0)
            {
               gcd--;
            }

         }

Before, the || sign was an &&, and we simply could not figure out why jGRASP kept returning 0/1 or 1/1 for the GCD when we input fractions that needed to be simplified. 0 and 1 are two of the most common GCD's when simplifying, and it makes sense in a context like this. For instance, if the fraction we entered was 16/8, the program could only increment downward if BOTH of the numbers' remainders were not 0. 

Overall, as I'm preparing for the test, I find that it's better to review all of the worksheets and quizzes in order to remember all of the information. The labs are also going to be a good source of studying because they contain a lot of the curriculum that we are learning in class. Hopefully, I can apply the information in the lab to the test.
