Because this system involves the problem of scanning files, scanning files is a key and difficult point of the whole project, so we make several sets of solutions for reference only. The control scanner is the requirement programming language to control the hardware, the system development is based on the web framework and cannot be controlled with the underlying hardware. Several solutions are presented as follows: First, the use of Java to write app

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

Scanner in the Java.util package, you need to import java.util.*, or import java.util.Scanner;How it works: by creating a Scanner object with new, scanner needs to pass in a system.in as a parameter, which we can consider to be the scanner of the data through its internal mechanism to wrap system.in. The
