   {/*from   w w  w.  j av  a2  s . co m*/
      Object objectRef = "hello"; 
      String string = "goodbye";  
      char[] charArray = {'a', 'b', 'c', 'd', 'e', 'f'};
      boolean booleanValue = true;
      char characterValue = 'Z';
      int integerValue = 7;
      long longValue = 10000000000L;
      float floatValue = 2.5f; 
      double doubleValue = 33.333;

      StringBuilder lastBuffer = new StringBuilder("last buffer");
      StringBuilder buffer = new StringBuilder();

      buffer.append(objectRef)
            .append("%n")
            .append(string)
            .append("%n")
            .append(charArray)
            .append("%n")
            .append(charArray, 0, 3)
            .append("%n")
            .append(booleanValue)
            .append("%n")
            .append(characterValue)
            .append("%n")
            .append(integerValue)
            .append("%n")
            .append(longValue)
            .append("%n")
            .append(floatValue)
            .append("%n")
            .append(doubleValue)
            .append("%n")
            .append(lastBuffer);

      System.out.printf("buffer contains%n%s%n", buffer.toString());
