    <p>I write a code sample about calculate the aritmetic mean,i did lots of thing but some parts are missing/incorrect.</p> <p>This is my code sample : </p> <pre><code>public static void main(String[] args) { int i; int j; int thelargest; int thesmallest; Scanner input = new Scanner(System.in); System.out.println("Enter the list of number : "); String input2 = input.nextLine(); String[] numbers = input2.split("\\s+"); int[] result = new int[numbers.length]; for (j = 0; j &lt; numbers.length; j++) { result[j] = Integer.parseInt(numbers[j]); } for (i = 0; i &lt; result.length; i++) { System.out.print(""); System.out.println(result[i]); } System.out.println("The Largest Number : " + findTheLargestNumber(result)); System.out.println("The Smallest Number : " + findTheSmallestNumber(result)); thelargest = findTheLargestNumber(result); thesmallest = findTheSmallestNumber(result); float arithmeticMean = (float) (result[i + j])// result.length; System.out.println("The Arithmetic Mean : " + arithmeticMean); </code></pre> <p>/*There is a mistake and I tried to solve it but I didn't find any way to solve it.I want my programme to sum the results(numbers) and divide into number of result.(For example :10+20+30=60 and the aritmetic mean is 60/3=20.)Lastly,I think the mistake is about (float)(result[i+j]).</p> <p>*/</p> <pre><code>} public static int findTheSmallestNumber(int[] series) { int thesmallest = series[0]; for (int i = 1; i &lt; series.length; i++) { if (series[i] &lt; thesmallest) { thesmallest = series[i]; } } return thesmallest; } public static int findTheLargestNumber(int[] series) { int thelargest = series[0]; for (int i = 1; i &lt; series.length; i++) { if (series[i] &gt; thelargest) { thelargest = series[i]; } } return thelargest; } </code></pre> <p>}</p> <p>Thanks for everbody which gonna help to me .</p>

    1. CO`result[i + j]` this should throw an *ArrayIndexOutOfBounds* exception.

    2. CO`result[i + j]` returns the element at the `i+j`-th position: (a) there might no item at this position and you will get an exception (b) even if there were an element at that position, there is no reason that it would be equal to the mean. You need to loop over the items and calculate the mean manually.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
