为什么System.out.print导致自动刷新？ [英] Why does System.out.print cause autoflush?

问题描述

System.out是一个PrintStream对象。我阅读了有关PrintStream的文档。我不明白为什么System.out.print导致缓冲区被刷新？

System.out is a PrintStream object. I read the documentation on PrintStream. What I don't get is why System.out.print causes the buffer to be flushed? Shouldn't that happen only for println?

推荐答案

那不是只发生在println吗？

Shouldn't that happen only for println?

Javadoc不会说何时刷新 。并且说将刷新到 println（） 或换行符上。

The Javadoc doesn't say when it won't be flushed. And it says it will be flushed on a println() or a newline.
