getRemainingCharacterCount

I need help i've written my code like that but i keep getting an error message so i can't seem to find the error i'm making.

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

  public Tweet(String text) {
    while(text.length() < MAX_CHARS) {
     this.text = text; 
    }
   }

  public String getText() {
    return text;
  }

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

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

Hey Elias Svoba

When I pass in the exact code you passed in, I too get an error without explanation, it seems to me there is some bug that causes the program that checks your solution to time out. Even though I'm not a pro, it seems to me your code is correct. You might consider reporting this bug to TeamTreehouse by shooting them an e-mail at help@teamtreehouse.com.

Here is a solution that does work:

    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; }

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

Hi Elias Svoba I assume the purpose of the code is to check if the tweet is longer than 140 characters. You should use “if” instead of "while". Every time you input text shorter the 140 characters you enter an infinite loop.
