There is far more methods in class Scanner than you'll need in this course. We only cover a small useful subset, ones this allow us to read in numeric

First, we should introduce the package import Java.util.Scanner; It is a simple text scanner that can use regular expressions to parse basic types and strings. Scanner uses the separator mode to decompose its input into tokens, which, by default, match the delimiter pattern. You can then use a different next method to convert the resulting token to a different type of value.Scanner reader=new

In our life, the use of more than the printer, but if it is in the office, then the scanner is more common, usually we will use the scanner to document or related documents to scan the surface into pictures, but some users are reflected in the link sweep negotiable, the driver installation failed, if the driver installation failed, Then it will mean that the scanner
