public interface Closeable extends AutoCloseable
Closeable 是可以关闭的数据源或目的地。调用 close 方法来释放对象持有的资源（如打开的文件）。

    • close

      void close() throws IOException
      关闭此流并释放与其关联的任何系统资源。如果流已经关闭，则调用此方法不会产生任何效果。

      如 AutoCloseable.close() 中所述，关闭可能失败的情况需要特别注意。强烈建议在抛出 IOException 之前放弃底层资源并在内部将 Closeable 标记为已关闭。

      close 在接口 AutoCloseable
      抛出:
      IOException - 如果发生 I/O 错误
