SNHU IT-145: Foundation in Application Development
IT-145 follows IT-140 and switches you from Python to Java, covering object-oriented basics — classes, objects, inheritance, and methods. The course builds toward a final project implementing a rescue-animal management system with multiple interacting classes.
Fennie is independent and not affiliated with Southern New Hampshire University. This is an unofficial study guide.
Build my IT-145 study planWhat makes it hard
The jump from Python's loose syntax to Java's strict typing, compilation errors, and class boilerplate is the main shock. Students who skated through IT-140 hit a wall when inheritance shows up, and the final project requires reading and extending provided starter code rather than writing everything fresh.
What you'll cover
- • Java syntax and compilation
- • Classes, objects, and methods
- • Inheritance
- • Input/output and the Scanner class
- • ArrayLists
- • Debugging compiler errors
The IT-145 study guide
How to study for SNHU IT-145, step by step.
- 1
Get Java compiling in week 1
Install the IDE and run a Hello World before the first assignment opens. Environment friction is wasted time once the 8-week clock starts ticking toward Sunday deadlines.
- 2
Map Java onto the Python you know
Keep a running translation sheet — how Java declares variables, writes loops, and reads input compared to IT-140's Python. The logic transfers; only the syntax is new at first.
- 3
Budget double time for the inheritance weeks
Inheritance is the first concept with no IT-140 equivalent, and it's the hinge of the final project. Slow down there even if earlier modules felt easy.
- 4
Read the starter code before extending it
The rescue-animal project grades your ability to understand provided classes as much as write new ones. Trace what the starter code does on paper before adding anything.

Put IT-145 on a Daily Plan
Upload the IT-145 module list to Fennie and it builds a day-by-day Daily Plan paced to your deadlines, with flashcards on the exact Java terminology your materials use and quizzes before each module wraps. Starting is free.

How Fennie helps with IT-145
Upload the IT-145 module list and Fennie's Daily Plans pace the Java units day by day around your Sunday deadlines, with extra time budgeted for the inheritance weeks. Use chat to untangle compiler errors conceptually and generate flashcards for Java terminology — access modifiers, constructors, method signatures — that the quizzes lean on.
FAQ
Is IT-145 harder than IT-140?
Most students say yes. Java is stricter than Python, and IT-145 introduces object-oriented concepts like inheritance that have no IT-140 equivalent. Budget more time per week than you did in IT-140.
What is the IT-145 final project?
A rescue-animal management system in Java. You extend provided starter classes, add an inheritance hierarchy, and implement a menu-driven program — reading the given code carefully matters as much as writing your own.
Do I need IT-140 before IT-145?
Yes, it's the prerequisite, and the course assumes you're comfortable with loops, functions, and basic data structures. If your IT-140 was a while ago, review Python logic first — the concepts transfer even though the syntax changes.

IT-140 — Introduction to Scripting
IT-140 is SNHU's first programming course, teaching Python through zyBooks labs over an 8-week term. It feeds into IT-145 and the CS sequence, and it ends with a final project where you build a text-based adventure game from scratch.
IT-200 — Fundamentals of Information Technology
IT-200 surveys the IT landscape — hardware, software, networks, data, and security — and how the pieces fit together in organizations. It's an early requirement in SNHU's IT degree, assessed through weekly discussions and scenario-based assignments rather than programming.
IT-235 — Database Design
IT-235 teaches relational database design from requirements: entity-relationship diagrams in Crow's Foot notation, normalization, and translating a business scenario into tables and relationships. The multi-part final project produces a complete database design package for a business case.
