I am having trouble becuase it doesnt say if i should creat a variable where to store the remainder of the characters?

should i do a 'for' to search the 'text' and how many characters are left?

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

  public Tweet(String text) {
    this.text = text;
  }

  public String getText() {
    return text;
  }

  public void setText(String text) {
    this.text = text;
  }
}

Hi Carlos Alberto Salcedo Valencia,

You could do that, but that would be making it harder on yourself. All you really need to do is get the length of the text which the user already has with text.length() and then substract MAX_CHARS by that length. The result then should be returned by the method.

Good luck!

i am haveing trouble because i have to return and INT and the variable i created to store subtraction from text.length and MAX_CHARS, is a String. the problem is telling me, Create a public method named getRemainingCharacterCount that returns an int representing how many characters they have left before they 140. Base your calculation on the field that stores the current text.

 public int getRemainingCharacterCount(){
    return MAX_CHARS - text.length();
  }
