- Create an overloaded method
- Differentiate between default and user defined constructors
- Create and overload 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
- Implement inheritance
- Develop code that demonstrates the use of polymorphism
- 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, RuntimeExceptions and Errors
- Create a try-catch block and determine how exceptions alter normal program flow

- Overload constructors and other methods appropriately
- Use the instanceof operator and casting
- Use virtual method invocation
- Override methods from the Object class to i mprove the functionality of your class
- Use package and import statements
Advanced Class Design
- Identify when and how to apply abstract classes
- Construct abstract Java classes and subclasses
- Use the static and final keywords
- Create top-level and nested classes
- Use enumerated types
Object-Oriented Design Principles
- Write code that declares, implements and/or extends interfaces
- Choose between interface inheritance and class inheritance
- Develop code that implements "is-a" and/or "has-a" relationships
- Apply object composition principles
- Design a class using the Singleton design pattern

- Sort and search arrays and lists
String Processing
- Search, parse and build strings
- Search, parse, and replace strings by using regular expressions, using expression patterns for matching limited to: . (dot), * (star), + (plus), ?, \d, \D, \s, \S, \w, \W, \b. \B, [], ().
- Format strings using the formatting parameters: %b, %c, %d, %f, and %s in format strings.
