This is a lot to ask!

So I already know I need to create a new method, and that in the method I will be getting the value of characters from the Tweet which I think means I will use a .atCharArray. I'm not sure if I'm supposed to attach that to the method name, or to something else.

Tweet.java 
public class Tweet {
  private String mText;
  public static final int MAX_CHARS = 140;
  public Tweet(String text) {
    mText = text;
  }

  public String getText() {
    return mText;
  }

}

Welcome to Treehouse! Let's take a look:

Task 2

Add a new method that returns the remaining characters available, based on the length of what is currently stored in mText.

I'm going to assume that by this point in the course you have a strong understanding of what creating a method and returning data means and the way in which one can do that in a general sense. For this challenge it sounds like we want to return the number of characters still available. That sounds like an int type and it should be the number of characters left.

For example, our max Tweet is 140 characters, if the length of our current text is 100 characters our method should return 40, correct (140-100) ? See if you can use that hint to get through the task.

Post back if you're still stuck.
