Ensure you've created a new public int field following the constant naming convention of MAX_CHARS

Can someone tell me what I am doing wrong and a quick and simple explanation on what a field is. Thank you!

Tweet.java 
public class Tweet {
  private String text;

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

  public String getText() {
    return text;
  }

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

  public final static int MAX_CHARTS = 140;
}

I don't know Java, but you have a Syntax error. The challenge is asking for MAX_CHARS not MAX_CHARTS. I tested it and it works fine spelled right. I also would declare this right below the declaration of text at the top instead of below your methods.

you spelled chars wrong. additionally, and these won't throw an error, but typically this would be put at the top before any methods, and static goes before final.

a field is just a variable in a class, so max_chars is a field and so is text. text is private so it can only be accessed by code in this class. max_chars is public so it can be accessed from any class in the application. text is not static, so it belongs to the instances of the class. each instance has its own value for text, which makes sense, each instance of a tweet is different. to access the non-static field text you need an object (instance) of the class. max_chars is static, so it belongs to the class. this makes sense here because all tweets have a max length of 140 chars. that value stays constant no matter how many tweets we make or if we make any at all. since this value is not going to change and exists irrespective of instances of the class, we make it public static final.
