I am getting a error:cannot find symbol when compiling

Question

I am trying to calculate and round up with an IF statement, the code is below. The error comes on the line: if (partterms < 6)

   // Setup Array List for Course CU
        ArrayList<Double> coursecu = new ArrayList<Double>();
  // Read inputs for Course Units and Sum the Value
        System.out.println("Please enter Individual Course CU values, Q to quit:");
        Scanner in2 = new Scanner(System.in);
        while (in.hasNextDouble())
        {
            coursecu.add(in.nextDouble());
        } 
        double sum = 0;
        for(int i = 0; i < coursecu.size(); i++)
        {
            sum = sum + coursecu.get(i);
        }
        System.out.println();
        System.out.println("Total Credit Units Required for Graduation");
        System.out.println(sum);
  // Calculate the Number of Terms to Completion
       {
          double fullterm = sum / planned_units; // Sets Whole Terms 
          double partterm = sum % planned_units; // Sets Partial Terms
        }
        if (partterm < 6)
        {
            number_terms = fullterms++;
        }
        else
        {
            number_terms = fullterms;
        }

Thanks Jeroen, I changed it back but it still gives the error. — rtruelock, Jan 05 '14 at 20:13
This question appears to be off-topic because it is about a code with a small typo. It will not be useful for anyone else visiting the site. — Sergey Kalinichenko, Jan 05 '14 at 20:13
Maroun, I am trying to calculate and round up the term number based upon the partterm value. Does that make sense? — rtruelock, Jan 05 '14 at 20:14
Thanks dasblinkenlight but fixing the typo did not change the error result — rtruelock, Jan 05 '14 at 20:15
This question was prompted by a problem that is unrelated to the actual question asked. While similar questions may be on-topic here, this one was solved by the asker in a manner unlikely to be relevant to others. This confusion can often be avoided by identifying and closely inspecting the shortest program necessary to reproduce the problem before posting. — Shog9, Jan 05 '14 at 20:41

{ ← 
    double fullterm = sum / planned_units; // Sets Whole Terms 
    double partterm = sum % planned_units; // Sets Partial Terms
} ←

Remove { and } and the variables will be known outside this weird block.

I don't think that will change something the brackets are just useless – Yehia Awad Jan 05 '14 at 20:15
@яша They limit the life of the variable to the block, only. – Maroun Jan 05 '14 at 20:16
nevertheless I have upvoted though it helps to improve the code – Yehia Awad Jan 05 '14 at 20:17

@яша Not only improve the code, it's actually the reason of the error. – Maroun Jan 05 '14 at 20:19

That did it!! wow, those two brackets, I am not sure why I had them in it. Thanks Maroun!! – rtruelock Jan 05 '14 at 20:20
@ᴍarounᴍaroun That's weird I didn't know that, Thanks for clarifying, one minute, if you create new unnecessary brackets, what would that do ? I mean in the design point of view ? – Yehia Awad Jan 05 '14 at 20:22
@яша Using them like this is to limit the variable scope.. See [this](http://stackoverflow.com/questions/1563030/anonymous-code-blocks-in-java) post. – Maroun Jan 05 '14 at 20:30
