如何在Java中将扫描器字符串转换为Stream？

您正在处理所有错误，

Scanner

try (final InputStream is = A.class.getResourceAsStream("data.txt");        final Reader r = new InputStreamReader(is, StandardCharsets.UTF_8);        final BufferedReader br = new BufferedReader(r);        final Stream<String> lines = br.lines()) {}

如果您确实要使用a

Scanner

implements Iterator

public Stream<String> streamScanner(final Scanner scanner) {    final Spliterator<String> splt = Spliterators.spliterator(scanner, Long.MAX_VALUE, Spliterator.ORDERED | Spliterator.NONNULL);    return StreamSupport.stream(splt, false) .onClose(scanner::close);}

PS，您似乎也没有关闭资源。 总是 关闭一个

InputStream
