Java Programming

ABOUT THE CLASSES
- Group classes conducted weekly once with 12 classes in each session.
- Classes are 1 hour and explore concepts through small example programs and simple explanations.
- Homework is assigned weekly, and help is available between classes via email.
- The levels described below typically take one 12-week session each with 1-3 hours weekly homework.
- Students are welcome to move faster — completing a level in less than 12 weeks by devoting more time to homework each week and using the unlimited email help available between classes.

WHY JAVA?
- One of the most popular and in-demand programming languages.
- Powers millions of devices worldwide.
- Used by computer science and programming elective courses in local high schools.
- Provides a head-start on preparation for the AP Computer Science A exam.
- Used by USA Computing Olympiad participants.

Description of the Units

Unit 1: Getting Started and Primitive Types

Learn the fundamentals of Java as well as other foundational concepts for coding.

Primitive data types including int, double, and Boolean
Evaluating arithmetic expressions in program code
Using assignment operators to produce a value
How variables and operators are sequenced and combined in an expression to create a result

Unit 2: Using Objects

Explore reference data as a way to represent real-world objects in a digital world and discover methods to perform more complex operations.

Objects and classes as ways to describe instances, attributes, and behaviors
Creating objects by calling constructors with and without parameters
Defining an object’s behavior using methods, including static and Math class
Using String objects and methods
Using application program interfaces (APIs) and libraries

Unit 3: Boolean Expressions and If Statements

Delve into the building blocks of algorithms and focus on using conditional statements to solve problems and control results.

Finding Boolean values with expressions involving relational operators
Using conditional statements to execute different statements based on input values
Building on conditional statements to create multiple possible outcomes
Creating the same value using equivalent Boolean expressions
Referencing objects with aliases

Unit 4: Iteration (Loops)

Learn about iteration, which is another building block of algorithms used for repetition.

Creating a loop to run an expression repeatedly until certain conditions are met
Standard arithmetic-based and String algorithms
Representing iterative processes in code using for and while loops
Nesting loop and iteration statements

Unit 5: Writing Classes

Explore how real-world interactions can be expressed digitally by organizing behaviors and attributes into classes, and you’ll examine the legal and ethical implications of computer programming.

The makeup of a class, including whether attributes are public or private
Setting an object’s attributes using constructors
Using comments to describe the functionality of code
Defining behaviors of an object using non-void, void, and static methods
Breaking problems into smaller parts by creating methods to solve individual subproblems

Unit 6: Arrays

Learn techniques and standard algorithms to work with collections of related data, known as data structures.

Representing multiple related items as array objects
Traversing an array by accessing the elements using iteration statements
Standard algorithms that utilize array traversals to perform functions

Unit 7: ArrayList

Delve deeper into data sets, exploring ArrayList objects for larger amounts of data, as well as the privacy concerns related to personal data storage.

Representing collections of related object reference data using ArrayList objects
Traversing an ArrayList by accessing the elements using iteration statements
Standard algorithms that utilize ArrayList traversals to perform functions
Searching and sorting using standard algorithms

Unit 8: 2D Arrays

Branch out into 2D arrays and experiment with data sets represented in a table.

Representing collections of data as arrays of arrays, or 2D arrays
Traversing a 2D array by accessing the elements using nested iteration statements

Unit 9: Inheritance

Learn how to manipulate programming without altering existing code by using subclasses to create a hierarchy.

Using common attributes and behaviors to group existing objects into superclasses
Defining and overriding methods within subclasses and superclasses
Creating references using inheritance hierarchies
Associating subclass objects with superclasses to create polymorphism

Unit 10: Recursion

Learn how to solve larger problems by solving smaller, simpler versions of the same problem using recursive methods.

Executing recursive methods
Searching and sorting using binary search and merge sort algorithms
