  • Determine the effect upon object references and primitive values when they are passed  into methods that change the values

Working with Inheritance 

  • Describe inheritance and its benefits

  • Develop code that makes use of polymorphism; develop code that overrides methods;  differentiate between the type of a reference and the type of an object

  • Determine when casting is necessary

  • Use super and this to access objects and constructors

  • Use abstract classes and interfaces

Handling Exceptions 

  • Differentiate among checked exceptions, unchecked exceptions, and Errors

  • Create a try-catch block and determine how exceptions alter normal program flow

  • Describe the advantages of Exception handling 

  • Create and invoke a method that throws an exception

  • Recognize common exception classes (such as NullPointerException, ArithmeticException, ArrayIndexOutOfBoundsException, ClassCastException)

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

  • Declare and use an ArrayList of a given type 

  • Write a simple Lambda expression that consumes a Lambda Predicate expression
