Reports type cast expressions where
|
|
the casted expression has a class/interface type that neither
|
|
extends/implements the cast class/interface type, nor has subclasses that do.
|
|
<p>
|
|
Such a construct is likely erroneous, and will
|
|
throw a <code>java.lang.ClassCastException</code> at runtime.
|
|
</p>
|
|
<p><b>Example:</b></p>
|
|
<pre><code>
|
|
interface A {}
|
|
interface Z {}
|
|
static class C {}
|
|
|
|
void x(C c) {
|
|
if (c instanceof Z) {
|
|
A a = ((A)c); // cast to incompatible interface 'A'
|
|
}
|
|
}
|
