  • Declare and initialize variables (including casting of primitive data types)
  • Differentiate between object reference variables and primitive variables
  • 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

  • Apply the static keyword to methods and fields
  • Create and overload constructors; differentiate between default and user defined constructors

  • 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
