Join Todd Perkins for an in-depth discussion in this video Input and output, part of Learning Java Applications (2016).
- The next item up for review is reading data to the console…and printing data out to the console.…Now, we've looked at printing data out to the console…quite a bit already.…So, we're mostly going to focus on…user input inside of the console…and using that inside of our applications.…So let's say our goal is to create a mini app…that just adds numbers together.…So, for example, we could start with…system.out.println…and we can ask the user to enter the first number.…
Now we want to capture number.…So what we do is create a scanner,…and this is one of multiple ways to capture user input,…but for now we're going to focus on just the scanner here.…So the scanner, we'll call this scan,…set it equal to a new instance of the scanner class,…and then we're going to pass in system.in…so we're grabbing that user input there.…Now, when we use scanner, we're seeing this error right here…and when you click on the error,…you see the error that's happening…because the scanner cannot be resolved to a type.…
So the suggestion is to import the scanner class.…
