Can the terminal method be applied multiple times to the same stream in Java's Stream API?

No, the terminal method in Java Stream API can only be applied once to a single stream. After calling a terminal method, the stream is considered closed, and reusing the same stream will result in an IllegalStateException.

If you need to perform multiple operations, you should create a new stream from the original collection or data source.

Example:

List<String> list = Arrays.asList("a", "b", "c");
Stream<String> stream = list.stream();
long count = stream.count(); // terminal method
// stream.forEach(System.out::println); // will throw IllegalStateException

// Correct:
list.stream().forEach(System.out::println);
