I have a problem i don't understand in the Challange task "PictureBook.java" part two.

The task is " Now add a String member variable named mTitle. Make it public."

the code i have writen is the same as i have in my project when folowing the previous videos.

public class PictureBook { public String mTitle() { } }

i then get a syntax error "./PictureBook.java:3: error: missing return statement } ^ 1 error"

But it do not understand the error, i have the "}" in the code ?

when i look at the similar code i have in my project it exactly the same just with different String name.

Can anyone help me understand this?

PictureBook.java 
public class PictureBook {
  public String mTitle() {

  }
}

The challenge is asking you to declare a member variable and you're declaring a method. Get rid of the parenthesis and curly brace and you'll have the variable definition. Right now you're declaring a method that returns a String which is why it's complaining about a missing return statement.
