instanceof
check for a different type.
Although this might be intended, such a construct is most likely an error, and will
result in a java.lang.ClassCastException
at runtime.
Example:
class Main {
int whenCharSequenceCastToNumber(Object o){
if (o instanceof CharSequence) {
return ((Number) o).intValue();
}
return 0;
}
int earlyReturnWhenNotCharSequence(Object o){
if (!(o instanceof CharSequence)) return 0;
return ((Number)o).intValue();
}
}
