Body
<p>I'm trying to create a loop where the user enters some values for pizza toppings. They can have pepperoni, pineapple etc. When they type "done" I want it to break out of the loop. I have this all working. Its just my for loop which is the problem. I have 4 pizza topping, so naturally I put it to loop around 4 times. But if the user types in a wrong value, that uses up one of my 4 loops. Now I could set the counter to 200 so they are very unlikely to get it wrong that many times. But i'm hoping there is a cleaner version. So it will keep prompting the user until "done" is typed in. I tried using a while loop, with the do-while nested within it. Something like </p> <pre><code> while( size != "done") </code></pre> <p>But that didn't work either. Hes my code : </p> <pre><code> public List<String> Input(){ List<String> toppings = new ArrayList<String>(); Scanner sc = new Scanner(System.in); String size; System.out.println("What pizza toppings; Pepperoni, Fungi, Pineapple or Bacon, type 'done' when your finished: "); FORLOOP: for(int i = 0; i < 4 ; i++){ do { size = sc.next(); if ( size.equalsIgnoreCase( "Pepperoni") || size.equalsIgnoreCase( "Fungi" ) || size.equalsIgnoreCase( "pineapple" ) || size.equalsIgnoreCase( "bacon" )) { toppings.add(size); } else if( size.equalsIgnoreCase( "done" ) ){ break FORLOOP; } else{ System.out.print("Choose either 'Pepperoni', 'Fungi', 'bacon' or 'pineapple' Toppings, type 'done' when finshed: "); } } while ( false ); } return toppings; } </code></pre>

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.
