nextShort(): Reads a single short value from the input.nextDouble(): Reads a single int value from the input.nextByte(): Reads a single byte value from the input.next(): Reads a single word value from the input.nextLine(): Reads a single line value from the input.nextBloolean(): Reads a single boolean value from the input.nextFloat(): Reads a single float value from the input.nextInt(): Reads a single int value from the input.In video game development, you can use it to build a character creation phase, where a user will enter information like their name.

For example, you can ensure that only permitted characters get validated and entered into the software database. In addition, scanner methods can help develop stringent rules and guidelines for user input, like the type and the amount of data it can accept.Ĭombining the Scanner with other functions, methods, etc., makes it an even more powerful tool. The Java Scanner class also comes with several methods to create more robust input collection techniques.

Next, let’s look at some of the most common methods used with the Scanner class, then we can dive into some code examples. Once you’ve imported the Scanner class, you can begin to use it in your code. At the top of every file is where all imports occur, and the utils import will often be one of the first imports you make.Īnd that’s it importing the Scanner class is as easy as it can get. The Scanner class comes in a commonly used package aptly named the utilities package.

Importing Scanner for use in your code is simple and only requires a singular line of code.

The following video shows an example of how to use the Java Scanner class to perform a function. You can even use the Scanner to control data format before entering it into a database. Those building websites with Java can use it to create a user sign-up/sign-in feature, ensuring that only the characters the developers deem safe can be entered.

Quite right, too, since it should be one of the easiest things to do, especially for software that requires a large amount of user input. The creators of the Java language considered that early on and provided the Scanner class to make this an easy process. This is a big deal since almost all software requires some degree of user interaction, and it needs a way to capture that data. In other words, it provides a way for the user to enter information that the software can use to inform its behavior. The Java Scanner is a class in the Java Utilities Package, and it serves the purpose of creating bi-directional communication between the software and its user. Without further delay, let’s jump right in.

How to Start Scanning for User Input With Java.

Finally, you will see some code examples from the view of developing a simple character creation phase for a hypothetical video game. You will also learn about the different methods that come with it and how they extend or specify the behavior of the scanner class. In this post, you will discover the Java class called Scanner and how to create an instance of it.
