Mode Method Help

[Carey]

please help me improve my mode method. its only got one problem. the first number in the array does funny things. put in 1,1,1,2,2,2,2,2. the answer should be 5 instances of 2, but the ones get included in there for some reason.

code:

public String mode()     {         int arrayCount = 0;         int[] highCount = new int[3];              //how many times a number appears in the array         double[] highNumber = new double[3];             //the number that appears most in the array         int modeCount = 1;                      //temp counter for how many times a number appears in the array (set to one to start)         double modeNumber = numbers[0];         //the number to start looking at and counting for         for (int a = 1 ; a < Array.getLength(numbers) ; a++)    //for how many numbers in the array         {             if (numbers[a] == modeNumber)              //if the number is the same as the number you are checking for...             {                 modeCount+=1;                   //add one to the count             }             else                                    //if it's not the same...             {                 if (modeCount > highCount[arrayCount] && modeCount > 1)      //if the number appears more times than the current highCount...                 {                     highCount[arrayCount] = modeCount;      //replace the record with the current stats                     highNumber[arrayCount] = modeNumber;                 }                 else if (modeCount == highCount[arrayCount] && modeCount > 1)                 {                     arrayCount +=1;                     if (arrayCount > 2)                     {                         return "No mode";                     }                     highCount[arrayCount] = modeCount;      //replace the record with the current stats                     highNumber[arrayCount] = modeNumber;                 }                 modeCount = 1;                  //set the modeCount to 1                 modeNumber = numbers[a];        //set the number you are checking for to the current number             }//end if statement         }//end for loop         if (modeCount > highCount[arrayCount] && modeCount > 1)      //if the number appears more times than the current highCount...         {             highCount[arrayCount] = modeCount;      //replace the record with the current stats             highNumber[arrayCount] = modeNumber;         }         else if (modeCount == highCount[arrayCount])         {             arrayCount +=1;             if (arrayCount > 2)             {                 return "No mode";             }             highCount[arrayCount] = modeCount;      //replace the record with the current stats             highNumber[arrayCount] = modeNumber;         }         if (arrayCount == 0)         {             if (highCount[0] == 0)             {                 return "No mode";             }             return highCount[0]+" of "+highNumber[0];         }         else if (arrayCount == 1)         {             return highCount[0]+" of "+highNumber[0]+", and "+highCount[1]+" of "+highNumber[1];         }         else if (arrayCount == 2)         {             return highCount[0]+" of "+highNumber[0]+", "+highCount[1]+" of "+highNumber[1]+", and "+highCount[2]+" of "+highNumber[2];         }         else         {             return "No mode";         }     }

The code provided is insufficient. It's missing context. Where does this "numbers" array come from?

i don't need help on the rest of the program, but since you asked so nicely here is the whole thing. its a BlueJ project, so if you don't use BlueJ, just delete everything except the Statistics.java file. also ignore the standard deviation image.

cmon people!!!! i need some help here!!!!


sorry about the necro-post, im desperate

I don't see a problem. After adding a main, I try your numbers 1,1,1,2,2,2,2,2 I get mode: 5 of 2. Exactly what I should get. Am I missing something here?
