Reports local variables that are "reused" overwriting their
|
|
values with new values unrelated to their original use.
|
|
<p>Such a local variable reuse may be confusing,
|
|
as the intended semantics of the local variable may vary with each use. It may also be
|
|
prone to bugs if due to the code changes, the values that have been considered overwritten actually
|
|
appear to be alive. It is a good practice to keep variable lifetimes as short as possible, and not
|
|
to reuse local variables for the sake of brevity.</p>

<p>Example:</p>
|
|
<pre><code>
|
|
void x() {
|
|
String s = "one";
|
|
System.out.println("s = " + s);
|
|
s = "two"; //reuse of local variable 's'
|
|
System.out.println("s = " + s);
|
|
}
|
