I have a Stream<Integer> and want to know if there is a null in this stream. How do I check that? Using .anyMatch(null) throws me a java.lang.NullPointerException.

We can use lambda expression str -> str!= null inside stream filter() to filter out null values from a stream.
In any of the cases your code is going to throw a NullPointerException. The exception can be avoided by adding Null checks.
anyMatch accepts a predicate.
stream.anyMatch(x -> x == null)
or
stream.anyMatch(Objects::isNull)
