Create a public method named getRemainingCharacterCount that returns an int showing how many characters are left

cant get this to work, its showing no error... i think theres no syntax error but the login isnt what they want... maybe i dont get the question. What am i doing wrong

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

  private String text;

  public int getRemainingCharacterCount(){
    int remainingchars=MAX_CHARS-text.length();

    while(remainingchars<= MAX_CHARS){
      System.out.printf("You have %d character left",remainingchars);
    }
    return remainingchars;
  }

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

  public String getText() {
    return text;
  }

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

Hi Thandolwethu,

your while loop will run endlessly if the character limit is not reached, because the remaining chars will always be less or equal to MAX_CHARS. Just replace the "while" with an "if" statement and you will be fine.

Kind Regards, Florian

Thanks Florian, whenever I added shorthand increment/decrement notations it would give values that are way off. To solve if all i did was remove everything inside the method except the return statement and it worked.
