    Default String help please!

    I've been going through the StringBuffer part of my unit and believe that I have gained enough understanding to manipulate the StringBuffer in a program. Yet each time I try to invoke one of the methods outlined in the unit, I'm given an error message. Is there something wrong with my syntax or logic? Is there something that I need to import? Any help would be appreciated. I am attaching my output below. Thank you all so much!

    public class StringBuffer
    {
    public static void main(String[] args)
    {
    StringBuffer sbuff = new StringBuffer();

    //one attempt to append - error
    sbuff.append("Jenna");

    //second attempt to append - error
    String phrase = new String("Jenna");
    sbuff.append(phrase);

    //attempts to call upon other methods - errors
    System.out.println("Your name backwards is: " + sbuff.reverse());
    System.out.println("The length of your name is: " + sbuff.length());
    }
    }

    Take a look at the name of your own class, and then tell me what you think will happen when you call, new StringBuffer. How does Java know which one you mean?
