# Syllabus
This course is taught in 8 modules and mimics the education you'd obtain if you sat through an entire year of introductory programming at the university level. I've taught intro-level programming for 6+ years and am acutely aware of what beginners need to see and hear. In short, **I DON'T SKIP STEPS!**.

The 8 modules included in this course are as follows:
1. [Basics](#module-1---basics)
2. [Functions and Storage](#module-2---functions-and-storage)
3. [Object-Oriented Programming](#module-3---object-oriented-programming)
4. [Exceptions and File Input/Output (I/O)](#module-4---exceptions-and-file-inputoutput-io)
5. [Memory Organization, Lambda Expressions and Basic Data Structures](#module-5---memory-organization-lambda-expressions-and-basic-data-structures)
6. [Threads, GUIs and APIs](#module-6---threads-guis-and-apis)
7. [Recursion](#module-7---recursion)
8. [Tranitioning to C++ (from Java)](#module-8---tranitioning-to-c-from-java)

   - Abstract Methods and Classes
   - Interfaces

## Module 4 - Exceptions and File Input/Output (I/O)
Module 4 covers intermediate to advanced topics of programming (in Java), specifically focusing on exceptions and file I/O. The content in this section is almost always taught in a "102"-style intro programming course, if it is covered at all. A wide variety of concepts are covered, but the high-level topics and goals of this module are broken down into the following lessons:
1. Basic Exception Handling (exceptions, try/catch/finally) [(more details)](Module_04_Exceptions_And_File_IO/src/clients/Lesson_01_Exception_Handling_Toy_Example.java)

## Module 5 - Memory Organization, Lambda Expressions and Basic Data Structures
Module 5 covers advanced topics of programming (in Java), specifically focusing on memory organization, lambda expressions and an intro to basic data structures. While memory organization may be taught in a "102"-style intro programming course, most of these topics are not covered at all in a "101" or "102"-level course. Topics in this course are taught to **expose** students to advanced topics so that they are more prepared for a course like Data Structures (typically comes after a "102"-style course). A number of high-quality slides are provided with this module since the concepts covered are more conceptual than previous content. A wide variety of concepts are covered, but the high-level topics and goals of this module are broken down into the following lessons:
1. Memory Organization (Stack vs. Heap) [(more details)](Module_05_Memory_Org_Lambda_Expressions_And_Datastructures/src/Lesson_01_Stack_Vs_Heap.java)
2. Performance & Functional Differences: ArrayList vs. LinkedList vs. Set [(more details)](Module_05_Memory_Org_Lambda_Expressions_And_Datastructures/src/Lesson_02_ArrayList_Vs_LinkedList_Vs_Set.java)
3. Lambda Expressions (passing methods as parameters) [(more details)](Module_05_Memory_Org_Lambda_Expressions_And_Datastructures/src/Lesson_03_Lambda_Expressions.java)
4. Sets (simple example) [(more details)](Module_05_Memory_Org_Lambda_Expressions_And_Datastructures/src/Lesson_04_Set_Basics_Countries_Visited_Example.java)
5. Maps (mapping a "primitive" to a "primitive") [(more details)](Module_05_Memory_Org_Lambda_Expressions_And_Datastructures/src/Lesson_05_Map_Simple_Values_Countries_Visited_Example.java)
6. Maps (mapping a "primitive" to a list) [(more details)](Module_05_Memory_Org_Lambda_Expressions_And_Datastructures/src/Lesson_06_Map_Complex_Values_Countries_Visited_Example.java)
7. Maps (sorting by map key, sorting by map value) [(more details)](Module_05_Memory_Org_Lambda_Expressions_And_Datastructures/src/Lesson_07_Maps_Table_Contents_Word_Count_Example.java)

## Module 6 - Threads, GUIs and APIs
Module 6 covers advanced topics of programming (in Java), specifically focusing on threads, GUIs and APIs. While this module may prove to be the most fun for students, these topics are typically not covered in a "101"- or "102"-style intro programming course. These are **essential** topics that most students are forced to teach themselves. Understanding these topics well, even in the context of Java, will prepare students to jump into web-app or mobile-app platforms much more easily.A wide variety of concepts are covered, but the high-level topics and goals of this module are broken down into the following lessons:
1. Theads (breaking up tasks to increase performance) [(more details)](Module_06_Threads_GUIs_And_APIs/src/main/java/Lesson_01_Threads.java)
2. Hand-coded GUI Creation (components, layouts, event handlers) [(more details)](Module_06_Threads_GUIs_And_APIs/src/main/java/Lesson_02_Handcoded_GUI_Self_Destructing.java)
3. APIs, JSON, External Libraries and Maven (making Yelp API calls and parsing response data, adding external libraries) [(more details)](Module_06_Threads_GUIs_And_APIs/src/main/java/Lesson_03_APIs_JSON_Libraries_Maven.java)
4. WindowBuilder GUI and APIs (making a GUI using a GUI-builder) [(more details)](Module_06_Threads_GUIs_And_APIs/src/main/java/Lesson_04_Windowbuilder_GUI_APIs.java)

## Module 7 - Recursion
Module 7 covers advanced topics of programming (in Java), specifically focusing on recursion. Recursion is taught in some "102"-style programming courses or not until a Data Structures course. Lessons in this course are taught to **expose** students to recursion so that they are more prepared for a course like Data Structures (typically comes after a "102"-style course) and are not meant to provide mastery. A wide variety of concepts are covered, but the high-level topics and goals of this module are broken down into the following lessons:
1. Recursive Math Examples (base cases, recursive cases) [(more details)](Module_07_Recursion/src/Lesson_01_Recursion_Math_Examples.java)
   - Recursive Powers Computation
   - Recursive Factorial Computation
   - Recursive Fibonacci Number Computation
   - Recursive Prime Computation
   - Recursive Decimal-to-Binary Computation
2. Binary Search Example [(more details)](Module_07_Recursion/src/Lesson_02_Recusion_Binary_Search_Example.java)

## Module 8 - Tranitioning to C++ (from Java)
Module 8 covers beginner and intermediate topics of C++, taught toward students who are well-trained in Java (like the students who completed Modules 1-7 of this course). A quick comparison is provided of syntax (Java vs. C++) and lessons demonstrate the differences of C++ when compared to the Java content covered in Modules 1, 2 and the portion of Module 3 covering basic classes. Lessons in this course are taught to **jump start** students into C++ so they have a solid foundation to confidently learn advanced C++ topics on their own. A wide variety of concepts are covered, but the high-level topics and goals of this module are broken down into the following lessons:
1. Basics (includes, console I/O, loops, conditional statements, arrays, vectors) [(more details)](Module_08_Transition_To_C++/Source/Lesson_01_C++_Basics.cpp)
2. Pointers (* and & syntax, pointer arithmetic) [(more details)](Module_08_Transition_To_C++/Source/Lesson_02_Pointer_Basics.cpp)
3. Functions (pass by value, pass by reference) [(more details)](Module_08_Transition_To_C++/Source/Lesson_03_Pass_By_Reference_Vs_Value.cpp)
4. Basic Classes (define macros, .h header files, .cpp source files, deconstructors) [(more details)](Module_08_Transition_To_C++/Source/Lesson_04_Burrito_Client.cpp)
