    <p>when I read the source code of java version 1.7.0_09, I found that the realization of toString method of Integer class uses negative int to calculate the mod operation, is there any sense to that? code is as follows:</p> <pre><code>public static String toString(int i, int radix) { if (radix &lt; Character.MIN_RADIX || radix &gt; Character.MAX_RADIX) radix = 10; /* Use the faster version */ if (radix == 10) { return toString(i); } char buf[] = new char[33]; boolean negative = (i &lt; 0); int charPos = 32; if (!negative) { i = -i; //***** change i to negative } while (i &lt;= -radix) { buf[charPos--] = digits[-(i % radix)]; //***** change back to positive after //***** mod operation i = i / radix; } buf[charPos] = digits[-i]; if (negative) { buf[--charPos] = '-'; } return new String(buf, charPos, (33 - charPos)); } </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.
