flushing input stream: java
提问by Terman
Is there a way to flush the input stream in Java, perhaps prior to closing it? In relation to iteratively invoking the statements below, while reading several files on disk
有没有办法在 Java 中刷新输入流，也许是在关闭它之前？关于在读取磁盘上的多个文件时反复调用以下语句
InputStream fileStream = item.openStream();
fileStream.close;
回答by spa
InputStreamcannot be flushed. Why do you want to do this?
OutputStreamcan be flushed as it implements the interface Flushable. Flushing makes IMHO only sense in scenarios where data is written (to force a write of buffered data). Please see the documentationof Flushablefor all implementing classes.
InputStream无法冲洗。你为什么要这样做？
OutputStream可以在它实现接口时刷新Flushable。冲洗使恕我直言仅在写入数据的情况下有意义（以强制写入缓冲数据）。请参阅该文档的Flushable所有实现类。
