在 Java 中，flush() 方法用于流中。但是我不明白使用这种方法的全部目的是什么？
fin.flush();
告诉我一些建议。
最佳答案
来自docs flush 方法:
Flushes the output stream and forces any buffered output bytes to be written out. The general contract of flush is that calling it is an indication that, if any bytes previously written have been buffered by the implementation of the output stream, such bytes should immediately be written to their intended destination.
缓冲主要是为了提高 I/O 性能。更多信息可以阅读这篇文章:Tuning Java I/O Performance .
