java.lang.IllegalArgumentException: wrong number of arguments

I am not sure why I am getting this error.

Tweet.java 
public class Tweet {
  private String mText;
  public static final int MAX_WORD = 140;


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

  public int getRemChar(String text) {
    int len = text.length();
    return len;
  }


  public String getText() {
    return mText;
  }

}

Well there are couple of mistakes.

1) This method should use mText, so no need to pass String to it 2) It should give answer of difference between mText length and MAX_WORDS

public int getRemChar () {
    int len = MAX_WORD - mText.length();
    return len;
  }

try this
