Summary:The recent enterprise online written test, found that most of the enterprise's written test platform using the game Code network (although a lot of slots), and on-line programming needs to use scanner to read the input of the program, therefore, the author on the achievements of the ancestors of scanner did a new, detailed summary. We know that Java.util.Scanner is a new feature of JAVA5, and the ma
WORD2013 has been out for a long time and there are many functions that need to be networked to complete. Today we are going to introduce the Office application-the use of barcode generator, with it we can make a variety of bar code more convenient, do not require us to spend additional time and effort to produce, the following is the procedure.

Let's look at the exact words in the Java API documentation:当扫描器抛出 InputMismatchException 时,该扫描器不会传递导致该异常的标记,因此可以通过其他某种方法来获取或跳它。 这是java API文档中的原话。In fact it means: "'If you enter the a character when the Nextint method executes, and you do not successfully parse an integer at this time, your input wi
() method and the Nextline () method, because Nextline () consumes the line feed. You can refer to the correct wording of this program (Http://code.geeksforgeeks.org/CErAhD). This problem and the scanf () in C + + (http://www.geeksforgeeks.org/problem-with-scanf-when-there-is-fgetsgetsscanf-after-it/) Method follows the same problem as the gets () method.
