'Iterator.next()' which can't throw 'NoSuchElementException'
Reports implementations of Iterator.next()
that cannot throw java.util.NoSuchElementException
.
Such implementations violate the contract of java.util.Iterator
, and may result in subtle bugs if the iterator is used in a non-standard way.
Example:
class Numbers implements Iterator<Integer> {
@Override
public Integer next() { //warning
if (hasNext()) {
return generateNext();
} else {
return null; //throw NoSuchElementException instead
}
}
...
}
