    <p>I'm old school, so I believe in only one entry and exit point for a method or function...</p> <p>The essence of your problem comes down to the compilers inability to guarantee that any one <code>if</code> statement "may" be meet (you and I know that the last one should be, but the compiler won't take that risk).</p> <p>So instead of having a <code>return</code> for every condition, you could define a single <code>return</code> variable and change it's value based on your needs, for example...</p> <pre><code>String getMaturityLevel(int age) { String maturity = "antique"; if(age &lt; 2) maturity = ("a baby"); else if(age &lt; 4) maturity = ("a toddler"); else if(age &lt; 13) maturity = ("a child"); else if(age &lt; 20) maturity = ("a teenager"); else if(age &lt; 35) maturity = ("a young adult"); else if(age &lt; 65) maturity = ("middle aged"); else if(age &lt; 100) maturity = ("geriatric"); return maturity; } </code></pre> <p>Now, in this small piece of code, it may not make much difference, but when you deal with methods that are longer or have multiple compound if/loop statements, a single <code>return</code> statement anywhere in the code can ruin your understanding of what you think the method is doing...it's a nit pick, but anything that makes my life easier ;)</p> <p>I would also encourage you to use <code>{...}</code> around your <code>if</code> statements, it will stop you from doing something like...</p> <pre><code>else if(age &lt; 100) maturity = ("geriatric"); maturity = "Why is the returned value for every condition?"; </code></pre>

    1. COThankyou I was trying to lean towards one return statement at the end but was unsure how to do it, also we are told not to use {} unless its going to be a block. ie more than one command executed at a time. But in future I'll take it on board as we want code to be easily understandable.

    2. COThe problem with not using `{...}` around your `if` blocks is that it's really easy to miss putting a extra line of execution where you expect it to be run for only the condition you want, but end up finding it gets executed every time...nasty debugging fun ;) - Also, as someone who has being in the industry some 14+ years, I'd say `if(something){ singleLine }` is more then acceptable ;)

    3. COSeconded, `if something {do_work;}` is acceptable, readable and your compile won't care. But `if something do_work; do_more_work;` will crash. The best practice is to be more robust than efficient.

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.
