In this video, Doug Winnie shows how to capture input from the user to create an interactive Java program. Through using features of the Java language, including them using import statements, users can enter text into the console and have it saved as variables in the program.
- [Instructor] So far, all of our programs…haven't had any interaction with the user.…We've coded the Java and built and ran the program.…Programs need to have ways to interact with the user.…And that happens in multiple ways.…Using the keyboard, mouse, and even with your voice or body.…The simplest is to interact with the keyboard.…For our console application, we can do that…by allowing the user to enter text into the console.…Java applications have many ways to capture input,…and they vary between frameworks.…So we'll use a simple example here for our program.…
Before we start adding in some code,…let's look at what we start with.…This is essentially an empty project.…But there is one line at the top…on line three, import statement.…When we work with Java, there are parts…of the Java language, or development kit,…that are included with our project automatically.…Everything we've been using so far…has been part of the basic Java system.…But when you work with something…outside of the core language,…you need to explicitly add it to your project.…
