Logging class with static members

I created a class, that roughly looks like this. Does pattern of such type of class (accessible everywhere, without instance) has some name? Or this is typical Utility pattern?

public class CodingLogger {
  private static StringBuffer buffer = new StringBuffer();
  public static void println(Object o) {
    System.out.println(String.valueOf(o));
    buffer.append(String.valueOf(o) + LINE_SEPARATOR);
  }
}
