  • Know how to read or write to object fields

  • Explain an Object's Lifecycle (creation, "dereference by reassignment" and garbage collection)

  • Develop code that uses wrapper classes such as Boolean, Double, and Integer

Using Operators and Decision Constructs

  • Use Java operators; use parentheses to override operator precedence

  • Test equality between Strings and other objects using == and equals ()

  • Create if and if/else and ternary constructs

  • Use a switch statement

Creating and Using Arrays

  • Create and overload constructors; differentiate between default and user defined constructors

  • Apply access modifiers

  • Apply encapsulation principles to a class

  • 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

  • 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
