How can I iterate over a list in Java using streams?

How can I iterate over a list in Java using streams?

You can use the stream() method on the list, followed by forEach() to iterate over the elements.

Can you show me a code example?

Sure! Here's a simple example:

List<String> names = Arrays.asList("Alice", "Bob", "Charlie");
names.stream().forEach(name -> System.out.println(name));

What if I want to filter the list before iterating?

You can use the filter() method before forEach(). For example:

names.stream().filter(name -> name.startsWith("A")).forEach(System.out::println);

Is there a way to collect the results into a new list?

Yes! You can use the collect() method with Collectors.toList(). Here's how:

List<String> filteredNames = names.stream().filter(name -> name.startsWith("A")).collect(Collectors.toList());
