Experimenting with the Code (OPTIONAL)

These are optional steps you can take If you’re interested in experimenting with the code in parts 1 and 2 of the practice set. You’ll need to do the following steps in your Practice Set 2 project that you just created.

Step 1 : Add the Display Code to Java

Delete everything in MainActivity.java. Then copy over all of the code in this gist into the MainActivity.java file.

Step 2 : Add the Display Code to XML

Delete everything in activity_main.xml. Then copy over all of the code in this gist into the activity_main.xml file.

Step 3 : How to use your new code

At this point, you’re set to experiment with the code in parts 1 and 2 of this practice set. You'll find the code in the Instructor Notes.

The code will always have this heading and look like this example below:

Code

Declaration and initialization one

String-name = "Katherine";

Declaration and initialization two

String "name" = "Kunal";

Declaration and initialization three

String name on profile = "Lyla";

or be linked in a gist like this one

Copy the code below the comment in onCreate that says:

Then you can run your app to see what the does.

You can practice this now. Add the following code after the comment in onCreate:

display1("This is Box 1.");
display2("And this is Box 2.");
display3("And look! Box 3!");

Which should display:

This is Box 1.
And this is Box 2.
"And look! Box 3!"

Happy coding!
