          @Deprecated
          public static LogStream log(String name)

      Deprecated. no replacement
      Return the LogStream identified by the given name. If a log corresponding to "name" does not exist, a log using the default stream is created.
      Parameters:
        `name` - name identifying the desired LogStream
      Returns:
        log associated with given name
      Since:
        JDK1.1

    - #### getDefaultStream

          @Deprecated
          public static PrintStream getDefaultStream()

      Deprecated. no replacement
      Return the current default stream for new logs.
      Returns:
        default log stream
      Since:
        JDK1.1

          @Deprecated
          public static void setDefaultStream(PrintStream newDefault)

      Deprecated. no replacement
      Set the default stream for new logs.
      Parameters:
        `newDefault` - new default log stream

      Overrides:
        `write` in class `PrintStream`
      Parameters:
        `b` - The byte to be written

      Deprecated. no replacement
      Write a subarray of bytes. Pass each through write byte method.
      Overrides:
        `write` in class `PrintStream`
      Parameters:
        `b` - A byte array
        `off` - Offset from which to start taking bytes
        `len` - Number of bytes to write
      Since:
        JDK1.1
      See Also:
        `FilterOutputStream.write(int)`

    - #### toString

          @Deprecated
