• Import other Java packages to make them accessible in your code
• Compare and contrast the features and components of Java such as: platform independence, object orientation, encapsulation, etc.

• 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

• Use Java operators; use parentheses to override operator precedence

• 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

• 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

• 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
