Problem with Code

[Norm]

non-static method trimmed(String) cannot be referenced from a static context

Change the definition of trimmed() to be static so that it can be called from a static method.

Woohoo almost figured this out but stuck on the bottom of code.

 while(loop)
            {
             //Get the next line in the file
                String curString = s.nextLine();
                //Trim and Squeeze
                System.out.print ( "Trim & Squeeze: " + ThreeMethods.squeeze(ThreeMethods.trimmed(curString)) + "\n");
                //Trim, Squeeze, and Shorten to 10 characters
                System.out.print ( "Trim, Squeeze, Shorten to 10: " + ThreeMethods.trimmed(ThreeMethods.squeeze(ThreeMethods.trimmed(curString)),10) + "\n");
                //Trim, Squeeze, lower-case and shorten to 20 characters
                System.out.print ( "Trim, Squeeze, Shorten to 20, lower-case: " + ThreeMethods.trimmed(ThreeMethods.trimmed(ThreeMethods.squeeze(ThreeMethods.trimmed(curString)),20)) + "\n");
                System.out.print ( "\n");
            }

What am i missing??
Error I am getting is this - error: cannot find symbol
String curString = s.nextLine();
symbol: variable s
location: class A3MO6252017

My brain is in a fog right now from looking at it so much. Any help would be great.
Thank you!

error: cannot find symbol
String curString = s.nextLine();
symbol: variable s

The compiler can not find a definition for the variable: s that is in scope where it is used.

Where is s defined?
