Create a public method named getRemainingCharacterCount that returns an int representing how many characters they have l

I simple have no idea how to get past this code challenge can somebody please help I am still new to java and some of these explanations I find them confusing:

public class Tweet {
  private String mText;
  public static final int MAX_CHARS= 140;

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

  public String getText() {
    return mText;
  }

  public getRemainingCharacterCount(){
    return int mText < 140;
  }

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

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

  public String getText() {
    return mText;
  }

  public getRemainingCharacterCount(){
    return int mText < 140;
  }

}

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

You don't need to create mtext. you shouldn't replace text to mtext, because of this you created an error. Hope this helps.

Thanks, Lawrence

For me ``` 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(); } } ```

It worked out perfectly. I haven't changed this.text and it was easier.

Thanks Robert!

The mText stuff was driving me crazy with lots of compile errors. Replacing the 2nd part with {this.text = text;} saved me.

You can subtract the length of mText from the maximum number of characters, MAX_CHARS, to find the remaining character count.

Hi Kourosh, how do Ido that? Like this? But still this is not working. I now just want to get past this code challenge I will return back to it one day when I know more java to try to analyse it. :)

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

You're almost there. The method needs a return type which should be int, so add that after public. Also you've forgotten the parenthesis for the length() method.

The problem may actually be related to the constructor. You only need to set mText in there:

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

depending on where you inserted it, you may need to delete or add some {} these always get me. ALAWAYS. good luck

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

i put it exactly like this, not messing with any of my braces. took me like 15min.

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

worked for me, but i had lots of issues with my braces {}
