    <p>Write a program to print out all possible values of int data type from the smallest to the largest, using Java.</p> <p><strong>Some notable solutions as of 8th of May 2009, 10:44 GMT:</strong></p> <p>1) Daniel Lew was the first to post <a href="https://stackoverflow.com/questions/835648/all-possible-values-of-int-from-the-smallest-to-the-largest-using-java/835666#835666">correctly working code</a>.</p> <p>2) Kris has provided <a href="https://stackoverflow.com/questions/835648/all-possible-values-of-int-from-the-smallest-to-the-largest-using-java/835841#835841">the simplest solution</a> for the given problem.</p> <p>3) Tom Hawtin - tackline, came up arguably with <a href="https://stackoverflow.com/questions/835648/all-possible-values-of-int-from-the-smallest-to-the-largest-using-java/835926#835926">the most elegant solution</a>.</p> <p>4) mmyers pointed out that printing is likely to become a bottleneck and <a href="https://stackoverflow.com/questions/835648/all-possible-values-of-int-from-the-smallest-to-the-largest-using-java/835681#835681">can be improved through buffering</a>.</p> <p>5) Jay's <a href="https://stackoverflow.com/questions/835648/all-possible-values-of-int-from-the-smallest-to-the-largest-using-java/837436#837436">brute force approach</a> is notable since, besides defying the core point of programming, the resulting source code takes about 128 GB and will blow compiler limits.</p> <p>As a side note I believe that the answers do demonstrate that it could be a good interview question, as long as the emphasis is not on the ability to remember trivia about the data type overflow and its implications (that can be easily spotted during unit testing), or the way of obtaining MAX and MIN limits (can easily be looked up in the documentation) but rather on the analysis of various ways of dealing with the problem.</p>

    1. COWas this a real interview question? How awful. I hate useless interview questions. I'd seriously look at them and say "why would anyone ever write that".

    3. COSome companies use questions like this as a quick weed out question. Usually it's over the phone, but occasionally you'll get one face to face. Don't be so surprised, the questions do get harder.

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.
