Number syntax 可以通过以下正则表达式语法来指定可由该类的实例解析为数字的字符串,其中Rmax是所使用的基数中的最高位(例如,基数10中的Rmax是9)。 NonAsciiDigit: 非ASCII字符c, Character.isDigit (c)返回true Non0Digit: [1- Rmax ] | NonASCIIDigit 数字: [0- Rmax ] | NonASCIIDigit Groupe...
如果底层可读的Readable.read(java.nio.CharBuffer)方法的调用会抛出一个IOException,则扫描器将假定输入的结尾已经到达。 由底层可读最新抛出IOException可以通过检索ioException()方法。当一个Scanner关闭时,如果源实现了Closeable接口,它将关闭其输入源。A Scanner对于无需外部同步的多线程使用是不安全的。除非...
