    <p>My assignment asks me to make a TV show program, where I can input shows, delete, modify and sort them. What I'm stuck on is the sorting part. The program prompts the user for the name of the show, day a new episode premieres, and time, which are stored in the array. It's sorts by the keys name, day, and time (alphabetically and numerically). </p> <p>The program prompts the user to input one of those keys, then the program needs to sort the shows by that key (sorting by day will sort alphabetically). </p> <p>I made a class and used an array to save the inputted shows. Here is the class: </p> <pre><code>public class showInfo { String name; String day; int time; } </code></pre> <p>I've inputted the shows like this: </p> <pre><code>public static void addShow() throws IOException { //initialize counter int i = 0; arr = new showInfo[i]; showInfo temp = new showInfo(); //input information do { System.out.print("Enter the name of show: "); String showName = br.readLine(); temp.name = showName; System.out.print("Enter which day of the week a new episode premieres: "); String showDay = br.readLine(); temp.day = showDay; System.out.print("Enter time in 24-hour format (e.g. 2100, 1900): "); int showTime = Integer.valueOf(br.readLine()).intValue(); temp.time = showTime; i++; System.out.print("Would you like to add another show? (y/n) "); } while((br.readLine().compareTo("n"))!=0); } </code></pre> <p>In order to sort by time, I've written the following method:</p> <pre><code>public static void timeSort() { int min; for (int i = 0; i &lt; arr.length; i++) { // Assume first element is min min = i; for (int j = i+1; j &lt; arr.length; j++) { if (arr[j].time &lt; arr[min].time) { min = j; } } if (min != i) { int temp = arr[i].time; arr[i].time = arr[min].time; arr[min].time = temp; } } System.out.println("TV Shows by Time"); for(int i = 0; i &lt; arr.length; i++) { System.out.println(arr[i].name + " - " + arr[i].day + " - " + arr[i].time + " hours"); } } </code></pre> <p>My problem is that when I call it and output it in the main, it only shows "TV Shows by Time" text, but not the shows. Why is this? (Should I show my full code?) </p> <p>I think my issue has something to do with the counter, but I'm not sure how I'd fix that since the user is supposed to input as many shows as they'd like and the amount of shows is modified and deleted in other methods.</p> <p>Any help would be great! Thanks in advance!</p>

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.
