Working with Selected classes from the Java API 
  • Manipulate data using the StringBuilder class and its methods
  • Create and manipulate Strings
  • Create and manipulate calendar data using classes from java.time.LocalDateTime,  java.time.LocalDate, java.time.LocalTime, java.time.format.DateTimeFormatter, java.time.Period
