1.Stream to List Example You can use the toList() method of the Collectors class to convert a Stream to List in Java 8. Here is an example of converting a stream of integers to a list of integers. The stream is from another list of Integers. ...
// Java 8, seem a bit long, but you can enjoy the Stream features like filter and etc. List<String> result5 = map.values().stream() .filter(x -> !"apple".equalsIgnoreCase(x)) .collect(Collectors.toList()); // Java 8, split a map into 2 List, it works!
