Are you asking how to create a method that returns a double? If so just place this within your class. You can also add parameters as well. I would recommend taking a few of the Java programming courses if you aren't familiar with how methods work.

public double GiveMeADouble()
{
     double test = 0.0;

     return test;

}

Hey John!

I believe you must've mis-read the question. We're creating member variables rather than classes so, we create these in the normal format of a variable:

public String myString = "This is a string";

So, you'll need to update the visibility (See the question), the variable type (Which should be either int or double (See the question to know which one to use)) and prefix with m for a member variable. Also, you don't need to set a value for the variable so, just end it with a ;.

Also, be sure to remove them brackets from your class declaration! We don't use brackets next to the class name - we use constructors for this instead but, you don't need to worry about this for the Code Challenge.

Hopefully, this should make sense now but, if there's still something you don't understand, give me a shout :)
