Barcode Scanner implementation on Java

Good sirs, I have a question. The school Java project I am currently working on requires me to have a USB Barcode Scanner as an external input to be connected to my laptop. I haven't actually bought the USB Scanner since it's quite expensive for a student. So I have to gather evidence that this Scanner would work with my program. Would the Scanner be able to read from a barcode (presumably printed off online) and store it into a variable? If so, is it true that the action event for the press of the scanner would be read exactly like a keyboard keypress? If so, what would the line of code look

问题 I have a barcode scanner (which acts like a keyboard) and of course I have a keyboard too hooked up to a computer. The software is accepting input from both the scanner and the keyboard. I need to accept only the scanner\'s input. The code is written in C#. Is there a way to \"disable\" input from the keyboard and only accept input from the scanner?

问题 This question already has answers here : Integrating the ZXing library directly into my Android application (16 answers) Closed 3 years ago . I\'ve been searching for how to add a barcode scanner to my app. Are there any examples or how can I do this easily? 回答1: The ZXing project provides a standalone barcode reader application which — via Android's intent mechanism — can be called by other applications who wish to integrate barcode scanning. The easiest way to do this is to call the ZXing

问题 I\'m writing this in mere desperation :) I\'ve been assigned to make a standalone barcode scanner (as a proof of concept) to an Android 1.6 phone. For this i\'ve discovered the ZXing library. I\'ve googled, read related topics here on StackOverflow used common sence and so forth. Nothing seemed to have helped, and i just can\'t punch a hole on this mentale blockade :/ I know it to be possible, to use the lib, and create your own standalone barcode scanner. I\'ve read that using the \"Barcode
