Create a random number generator

- [Teacher] When you roll a die,…you're taking a chance.…The chance is that you're going to get…a number from one to six appear on the die…when it is finished rolling.…In code, you simulate the die…using a random number generator.…In Java, to create the random number generator,…you'll use the random class.…This class, when it is instantiated,…allows you to generate a random number…using a range that you define.…In our code, we need to create…the generator for our app.…Open the MainActivity.java file.…We'll create a field in our class…to hold the instance of the random class.…

At the top, above the onCreate method,…create a field to hold our random class instance.…We'll use the class name Random,…and then we'll call it rand.…You'll need to import this class…using the Alt Enter shortcut for the IDE.…When the activity starts,…we need to create our instance of the random class…and assign it to the field.…We can do this at the bottom of the onCreate method.…We'll access our instance, rand,…and we'll set that to a new instance…
