<div class="block">Compares this object with the specified object for order. Returns a
negative integer, zero, or a positive integer as this object is less
than, equal to, or greater than the specified object.
<p>The implementor must ensure
<code>sgn(x.compareTo(y)) == -sgn(y.compareTo(x))</code>
for all <code>x</code> and <code>y</code>. (This
implies that <code>x.compareTo(y)</code> must throw an exception iff
<code>y.compareTo(x)</code> throws an exception.)
<p>The implementor must also ensure that the relation is transitive:
<code>(x.compareTo(y) &gt; 0 &amp;&amp; y.compareTo(z) &gt; 0)</code> implies
<code>x.compareTo(z) &gt; 0</code>.
<p>Finally, the implementor must ensure that <code>x.compareTo(y)==0</code>
implies that <code>sgn(x.compareTo(z)) == sgn(y.compareTo(z))</code>, for
all <code>z</code>.
<p>It is strongly recommended, but <i>not</i> strictly required that
<code>(x.compareTo(y)==0) == (x.equals(y))</code>. Generally speaking, any
class that implements the <code>Comparable</code> interface and violates
this condition should clearly indicate this fact. The recommended
language is "Note: this class has a natural ordering that is
inconsistent with equals."
<p>In the foregoing description, the notation
<code>sgn(</code><i>expression</i><code>)</code> designates the mathematical
<i>signum</i> function, which is defined to return one of <code>-1</code>,
<code>0</code>, or <code>1</code> according to whether the value of
<i>expression</i> is negative, zero, or positive, respectively.</div>
