Objects that implement this interface can have characters or character sequences appended to them. Appendable was added in Java 5.0 as a simple unifying API for StringBuffer and StringBuilder, java.nio.CharBuffer, and character output stream subclasses of java.io.Writer. The java.util.Formatter class can send formatted output to any Appendable object. See also Readable.

public interface Appendable {
// Public Instance Methods
     Appendable append(char c) throws java.io.IOException;  
     Appendable append(CharSequence csq) throws java.io.IOException;  
     Appendable append(CharSequence csq, int start, int end) throws java.io.IOException;  
}
