The instructions say, "Please add a new constant to store the maximum number of characters allowed which is 140. Use the proper access level modifiers to make it unchangeable and accessible right off of the class. Follow the proper naming convention."
The first thing to notice is that we need to add a constant to our code. We use constants to represent things that we know will never change (i.e hours in a day etc.). Our constant will be the max number of characters allowed in a tweet.
Whenever we need to add a constant to our code, we use the keyword final to make it unchangeable. Furthermore, we use all caps letters and place underscores in between words. Therefore, we know we need something like:
accessor final int MAX_CHARS = 140;
The instructions also state that we need to use an accessor that allows access right off the class. This means that we need to make it public and use the static keyword as well.
public static final int MAX_CHARS = 140;
I hope this helps.
Regards,
Chris
