In the above example, we tried to open a file and read it into the buffer from a file path. If the file exists and we are able to read the file, then no errors would be thrown, and the file buffer would get closed in finally block if it’s not null. Even if there is an erro...

Java 7引入了try-with-resources语句,它可以自动管理实现了AutoCloseable或Closeable接口的资源。这使得关闭流的代码更加简洁和安全。 代码示例 使用try-with-resources重写上述示例: try(FileInputStreamfis=newFileInputStream("example.dat");BufferedInputStreambis=newBufferedInputStream(fis);ObjectInputStreamois=newObject...
