Examples of java.util.logging.Formatter

java.util.logging.Formatter
A Formatter provides support for formatting LogRecords.
Typically each logging Handler will have a Formatter associated with it. The Formatter takes a LogRecord and converts it to a string.
Some formatters (such as the XMLFormatter) need to wrap head and tail strings around a set of formatted records. The getHeader and getTail methods can be used to obtain these strings. @version 1.17, 11/17/05 @since 1.4

      FileHandler handler = new FileHandler(outputFile.getPath());
      handler.setFormatter(new Formatter() {

        public String format(LogRecord record) {
