Thread: creating a new method that's not outputting correct result

I'm trying to create a new method called getTotal which is supposed to take all the numbers in the array and add each of them up to get a total of all the numbers. I was supposed to print each number in the array out in rows of 4 scores each which is done correctly. However, when I try and add the scores array to get a total I get a bunch of 0's out of nowhere. The output is below the code. What am I doing wrong?

 
import java.io.*;
 
 
public class staticMethods{
 
public static void main(String[] args) throws IOException{
 
	File dataFile = new File("C:\\Documents and Settings\\Mark\\Desktop\\Scores.txt");
	BufferedReader br = new BufferedReader(new FileReader(dataFile));
 
	String scoresString = new String();
	String[] scoresArray = new String[36];
	int[] scoresIntArray = new int[36];
 
	scoresString = br.readLine();
	scoresArray = scoresString.split(" ");
 
	for(int i = 0; i < scoresArray.length; i++)
	{
 
		scoresIntArray[i] = Integer.parseInt(scoresArray[i]);
		String displayRows = new String();
 
 
			if (i < scoresArray.length) {
                displayRows += scoresArray[i++];
            }
 
            if (i < scoresArray.length) {
                displayRows += " " + scoresArray[i++];
            }
 
           if (i < scoresArray.length) {
                displayRows += " " + scoresArray[i++];
            }
 
 
 
            if (i < scoresArray.length) {
                displayRows += " " + scoresArray[i];
            }
 
            System.out.println(displayRows);
 
 
 
	}
	br.close();
	getTotal(scoresIntArray);
 
}
 
 
			public static void getTotal(int[] scores)
				{
 
					int total = 0;
 
					for(int i = 0; i <scores.length; i++)
					{
						System.out.println(scores[i]);
						total = total + scores[i];
 
 
 
					}
 
					System.out.println("The total of the array is " + total);
 
 
 
			}
 
 
}

The total of the array is 688

It appears that you're incrementing i several times in the same iteration, hence it's exiting quicker. If all of them are occurring under the same condition, then combine them under the same if block.

if (i < scoresArray.length) {
displayRows += scoresArray[i++];
}

if (i < scoresArray.length) {
displayRows += " " + scoresArray[i++];
}

if (i < scoresArray.length) {
displayRows += " " + scoresArray[i++];
}



if (i < scoresArray.length) {
displayRows += " " + scoresArray[i];
}

Each of those i++'s is incrementing the variable i.
i++ is the same as i = i + 1;

I'm having trouble with another method I'm trying to create. I'm trying to find a position of a number in the array but I previously sorted it in the getMedian method. I thought when I sorted it in the median method, it only stays sorted for the median method. However, whenever I try to find a position of a number in the array it finds it in the sorted array, but I want to find it from the original array.

	File dataFile = new File("C:\\Documents and Settings\\Mark\\Desktop\\Scores.txt");

	String[] scoresArray = new String[36];
	int[] scoresIntArray = new int[36];
 
	scoresString = br.readLine();
	scoresArray = scoresString.split(" ");
 
	for(int i = 0; i < scoresArray.length; i++)
	{
 
		scoresIntArray[i] = Integer.parseInt(scoresArray[i]);
 
	}
 
		String displayRows = new String();
		for(int i = 0; i < scoresIntArray.length; i++)
		{
			displayRows += scoresIntArray[i++] + " " + scoresIntArray[i++] +  " " + scoresIntArray[i++] + " " + scoresIntArray[i] + "\n";
 
            }
	System.out.println(displayRows);
 
 
 
	br.close();
 
	getTotal(scoresIntArray);
	getAverage(scoresIntArray);
	getLowest(scoresIntArray);
	getHighest(scoresIntArray);
 
	getMedian(scoresIntArray);
	getPosition(scoresIntArray, 93);
 
}

						System.out.println(scores[j]);

					System.out.println("\nThe total of the array is " + total);
 
 
 
			}
 
			public static void getAverage(int[] scores){
				int total = 0;
				int average = 0;

				{
					total += scores[i];

					lowest = scores[i];

			public static void getHighest(int[] scores)
			{
				int highest = 0;
 
				for(int i = 0; i < scores.length; i++)
 
				{
					if(scores[i] > highest)
					{
						highest = scores[i];
 
					}
 
 
				}
				System.out.println("The highest number in the array is " + highest);
 
			}
 
		public static void getMedian(int[] scores)
		{
 
			int median = 0;
 
			Arrays.sort(scores);
 
 
			int middle = (scores.length / 2);
 
			if ( 0 == scores.length / 2)
 
			median = (scores[middle] + scores[middle+1])/2;
 
			else if (0 != scores.length / 2)
			{
				median = scores[middle];
 
			}
 
 
 
	System.out.println("The median of the array is " + median);
 
		}
 
 
		public static void getPosition(int[]scores, int number)
		{
 
			for (int i = 0; i < scores.length; i++)
 
 
				if(scores[i] == number)
			System.out.println("The position of the number in the array is " + i);
 
 
 
 
 
 
 
 
		}
}

How do I "unsort" it back to the original array?
