Using the Scanner for input

- [Instructor] In the previous video,…we created some code that used…the string's instance methods.…We set a string input and ran a bunch of…instance methods on it, such as toUpperCase and charAt.…In this video, we will make this program dynamic…by having the user actually input a value…that will be saved in the variable…and ultimately use these instance methods.…To do this, we'll use the scanner class.…The scanner is a part of Java's util package,…and so we'll write an import statement to import…that class so we can use it in our program.…

Up here, we're going to write import java.util.Scanner,…and this is what's going to allow us…to get input from the user.…Now that we have access to the class, we are going to create…an instance of the scanner with its constructor…and save it in a variable.…Going to the top of our main method here, we're going to go…Scanner sc = new Scanner(System.in).…Here, we give System.in as an input to…the scanner constructor so that the scanner knows…where to look for input.…

To get access to what the user inputs, we are going to…
