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.

Working With Java Data Types 

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

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

Describe the advantages of Exception handling
