簡介¶

public interface BaseStreamS extends BaseStream\> extends AutoCloseable public interface Stream extends BaseStreamStream<T>>

S同樣是stream，裡面不同（新的流對象）=> Stream<T>

S sequential();  // 調用sequential，返回一個新流
Stream<T> peek(Consumer<? super T> action); // 調用peek，返回一個新流

• A sequence of elements supporting sequential and parallel aggregate operations.

AutoCloseable¶

try (Stream<String> stream = list.stream()) {
  stream.onClose(() -> {
    System.out.println("1");
    throw new NullPointerException("1 exception");
  }).onClose(() -> {
    System.out.println("2");
    throw new NullPointerException("2 exception");
  }).forEach(System.out::println);
}

AbstractPipeline¶

Abstract base class for "pipeline" classes, which are the core implementations of the Stream interface and its primitive specializations. Manages construction and evaluation of stream pipelines.
