    <p>OK So I am making a bubble sorting program to make sure arrays are in order and I have the first class compiled fine now but the second one keeps giving me problems. Right now it says it is the wrong type so I changed the variable dif to a int instead of a double but then it says possible loss of precision. Here is the code for the first file.</p> <pre><code>public class BubbleSort { public static void sort(int[] a, int numberUsed) { int index; for ( int i =0; i&lt;numberUsed; i++) { for (index = 0; index&lt;a.length - 1; index++) { if (a[index]&gt; a[index + 1]) { interchange(index, index + 1, a); } //end of if () } //end of for () } //end of for () } private static void interchange(int i, int j, int[] a) { int temp1; temp1 = a[i]; a[i] = a[j]; a[j] = temp1; } } </code></pre> <p>and this is the second file that is giving me the problem</p> <pre><code>import java.util.Scanner; public class GolfScores { public static double[] diff = new double[5]; public static void printOutArray(double[] a) { System.out.println("Sorted array values:"); for (int i=0; i&lt;a.length; i++) { System.out.printf("%2.2f",a[i]); } //end of for loop System.out.println(); double Handicap= (diff[0])/1*0.96; System.out.printf("Handicap: %2.2f",Handicap); System.out.println(); } public static void main(String[]args) { //construct and declare three arrays Scanner keyboard = new Scanner(System.in); double[] rating = new double[5]; double[] slope = new double[5]; double[] score = new double[5]; int numberUsed = 0; int index = 0; //Print out directions for the user System.out.println("Calculate handicap for 5 games of golf. This program takes Scores, \nCourse Rating and Slope rating for 5 games. \n\nUsing those figures, the program calculates the differential\nfor each round entered using this formula:(Score - Course Rating) x113 / Slope Rating. \n\nThen uses the lowest differential to calculate handicap"); System.out.println(); //A do while loop that runs until index is great than 5 do { System.out.print("Enter golf scores for game " +(index+1)+ ": "); score[index]= keyboard.nextDouble(); System.out.print("Course rating for game "+(index+1)+ ": "); rating[index] = keyboard.nextDouble(); System.out.print("Course slope for game "+(index+1)+": "); slope[index] = keyboard.nextDouble(); index++; //index is the number of array indexed variables used so far } while((index&lt;5)); //this formula for all 5 arrays (Score- Course Rating) x 113 / Slope Rating diff[0]=((score[0]- rating[0]) * 113 / slope [0]); diff[1]=((score[1]-rating[1])*113/slope[1]); diff[2]=((score[2]-rating[2])*113/slope[2]); diff[3]=((score[3]-rating[3])*113/slope[3]); diff[4]=((score[4]-rating[4])*113/slope[4]); BubbleSort.sort(diff, diff.length);//passes value of diff array to BubbleSort.sort printOutArray(diff);//prints out diff array } } </code></pre>

    1. CODon't use bubblesort. It's a toy sort, used for "baby's first sort program", after which it should be forgotten and never used again. Whatever language you're using probably has other built-in sorts. Use them.

    2. CO@Paul : I would assume this is a homework assignment, and calling Arrays.sort is not allowed.

    3. COOnce more, if it's homework it would be REALLY NICE if the poster would tag or mentions so so that we can give an accurately targeted answer. Anyone who answers this question (as phrased) with anything but "Use arrays.sort" is wrong if it's not tagged as homework.

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.
