We've seen constructors being used before. It's time to learn how to write constructors for your own classes.

Read: http://docs.oracle.com/javase/tutorial/java/javaOO/constructors.html

Having read the article, some of the previous examples of constructors might start to make a bit more sense. For example, we've seen the Intent constructor before:

Intent intent = new Intent(this, SecondActivity.class);

Compare this to the documentation (https://developer.android.com/reference/android/content/Intent.html\#Intent\(\)\)). As we can see, there are a number of constructors available, and the above call corresponds to one of them. We've also seen a different constructor being used here: http://www.vogella.com/tutorials/AndroidIntent/article.html\#sending-out-explicit-or-implicit-intents. Having multiple constructors like this makes it easier to create the type of Intent we want.

Try: Make a constructor for the Student class that makes it easier to create a student. ie, can we create a Student object with a name, age, and phone number with one line of code?
