• 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

• Apply the static keyword to methods and fields

• 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

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