What is wrong?

Question

I have this question:
Create a public method named getRemainingCharacterCount that returns an int representing how many characters they have left before they 140. Base your calculation on the field that stores the current text.
And I have this code:
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 String getRemainingCharacterCount() {
  return MAX_CHARS - text.length();
  }
}
I keeps giving me an error that in line 18 (return MAX_CHARS - text.length();) the second variable is a String and I don't know why.
Can you please help me?
Andrei.
```Tweet.java
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 String getRemainingCharacterCount() {
  return MAX_CHARS - text.length();
  }
}
```

Hi there!  You're doing great! But you've confused Java a little bit here. When we write a function definition we specify what data type we're returning or void to return nothing. You're returning an int which is exactly what you should be returning, but you told Java that you're going to return a String.
You typed:
```java
  public String getRemainingCharacterCount() {
```
But you meant to type:
```java
  public int getRemainingCharacterCount() {
```
This tells Java that it can expect a data type of int to be returned from that function. That's why you're getting the error about not being able to convert between the data types.
Hope this helps! :sparkles:

  public String getText() {
    return text;
  }
  public void setText(String text) {
    this.text = text;
  }
  public int getRemainingCharacterCount() {
  return MAX_CHARS - text.length();
  }
}

It returns an int and not a String
change the return value from string to int and you are good to go
