Hi Tim McKyer,

For task one, we need to declare a constant that is 140 characters. The naming convention for constants, in Java, is to capitalize all of the letters. A constant is declared by using the keyword final.

For task 2 , we need to make a method that will return the remaining characters of the MAX_CHAR constant we declared in task 1. We do this by subtracting the characters that have already been used from the MAX_CHAR constant. getText().length() will give us the characters that have already been used. So, MAX_CHAR - getText().length(); will give us the remaining characters out of 140.

public class Tweet {
  private String mText;
  public static final int MAX_CHAR = 140; //task 1

  public Tweet(String text) {
    mText = text;
  }

  public String getText() {
    return mText;
  }
  //task 2
  public int getRemainingCharacters(){

    return  MAX_CHAR - getText().length();    
  }
}

If you have any other questions feel free to ask! Hope this helps!
