    <p>I'm creating a program that will calculate he cost of traveling. Each segment has a cost, and user is asked to enter the cost for each segment, then enter 3 segment ID's (0-6). The cost of the 3 ID's is added to give a final price.</p> <p>I need to repeat the program from the beginning if user enters >=1 (see comment at the end), how can I do this? Also, could I improve my program, and how?</p> <pre><code>import java.util.Scanner; public class AssignmentArrays{ public static void main(String[] args){ Scanner seg0 = new Scanner(System.in); Scanner seg1 = new Scanner(System.in); Scanner seg2 = new Scanner(System.in); Scanner seg3 = new Scanner(System.in); Scanner seg4 = new Scanner(System.in); Scanner seg5 = new Scanner(System.in); int[] data = new int [6]; data[0] = 0; data[1] = 0; data[2] = 0; data[3] = 0; data[4] = 0; data[5] = 0; /* Segment values */ while(data[0] == 0){ System.out.println("Enter cost for segment 0:"); data[0] = seg0.nextInt(); System.out.println("Enter cost for segment 1:"); data[1] = seg1.nextInt(); System.out.println("Enter cost for segment 2::"); data[2] = seg2.nextInt(); System.out.println("Enter cost for segment 3:"); data[3] = seg3.nextInt(); System.out.println("Enter cost for segment 4:"); data[4] = seg4.nextInt(); System.out.println("Enter cost for segment 5:"); data[5] = seg5.nextInt(); /* Path inputs */ Scanner node1 = new Scanner(System.in); Scanner node2 = new Scanner(System.in); Scanner node3 = new Scanner(System.in); int node1value; int node2value; int node3value; int pathCost; System.out.println("Enter ID of segment 0 of path:"); node1value = node1.nextInt(); System.out.println("Enter ID of segment 1 of path:"); node2value = node2.nextInt(); System.out.println("Enter ID of segment 2 of path:"); node3value = node3.nextInt(); /* Path cost calculation */ pathCost = data[node1value] + data[node2value] + data[node3value]; System.out.println("The cost of the trip is: $" + pathCost); /* Repeate or end program */ Scanner end = new Scanner(System.in); int userChoice; System.out.println("Enter 0 to exit or any other number to evaluate another path:"); userChoice = end.nextInt(); if (userChoice == 0){ System.out.println("The program has ended"); break; } else if(userChoice &gt;= 1){ /* REPEATE ALL OF THE ABOVE HERE */ } } } } </code></pre>

    2. CO6 Scanners? 1 is more than enough. Also if you want to repeat the whole program on `1` as input. just enclose the relevant part of code that you want repeated inside a while loop that loops if `userChoice` is 1

    3. COI think I understand. What about the scanners? How am I supposed to do it instead?

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.
