Reads text from a character-input stream, buffering characters so as to provide for the efficient reading of characters, arrays, and lines. 从字符输入流读取文本,并且缓冲字符,以便提供对字符、数组和行的有效读取。 The buffer size may be specified, or the default size may be used. The default i...
the example below the behaviour will be to save: # after 900 sec (15 min) if at least 1 key changed # after 300 sec (5 min) if at least 10 keys changed # after 60 sec if at least 10000 keys changed # # Note: you can disable saving at all commenting all the "save" lines. ...

lines.onClose( () -> System.out.println("Done!") ).forEach( System.out::println ); } Stream的方法onClose返回一个等价的有额外句柄的Stream,当Stream的close()方法被调用的时候这个句柄会被执行。Stream API、Lambda表达式还有接口默认方法和静态方法支持的方法引用,是Java 8对软件开发的现代范式的响应。
