UMGC CMSC 115: Introductory Programming
CMSC 115 is the first programming course in UMGC's computer science major, teaching Java fundamentals (variables, control flow, methods, and arrays) through hands-on projects with professional tools. It's the gateway to the CMSC sequence and moves at a brisker, more engineering-minded pace than the CMIS introductory track.

What makes it hard
Java is a strict first language: compilation errors, types, and boilerplate frustrate beginners who expected to write logic, not fight syntax. The weekly programming projects in an 8-week session leave no slack, and students who don't build a debugging routine early spend their weekends staring at stack traces.
What you'll cover
- • Java syntax, variables, and data types
- • Selection and loops
- • Methods
- • Arrays
- • Testing and debugging
- • Documenting and structuring programs
The CMSC 115 study guide
How to study for UMGC CMSC 115, step by step.
- 1
Get your Java environment running before week 1 ends
Install the JDK and IDE and have a program compiling on day one. Environment friction is dead weight in an 8-week session, especially when projects are due weekly.
- 2
Code a little every day around your schedule
Programming fluency is rep-built, and CMSC 115's weekly projects assume the previous week's skills are warm. Short daily sessions fit a work or duty schedule better than weekend marathons and teach more.
- 3
Read compiler errors as instructions, not insults
Java's error messages name the line and the problem. Building the habit of reading them top to bottom, fixing one error at a time, is the debugging routine the whole course runs on.
- 4
Trace your code by hand before running it
Walk a loop on paper, tracking each variable line by line. Hand-tracing builds the mental model that makes both the projects and any code-comprehension questions dramatically faster.

FAQ
Is UMGC CMSC 115 hard?
It's a real programming course, not a survey. Beginners should expect weekly projects and a steady ramp. Java's strictness is the early hurdle; students who practice daily rather than weekly handle the 8-week pace fine.
What's the difference between CMSC 115 and CMIS 102?
CMSC 115 is the computer science major's Java-based programming course; CMIS 102 is a gentler problem-solving introduction using Python. Which you need depends on your degree program, so check your plan before registering.
What language does CMSC 115 use?
Java, with professional development tools. The fundamentals you build (types, control flow, methods, arrays) carry directly into the intermediate Java courses that follow.
More UMGC courses
CMIS 102: Introduction to Problem Solving and Algorithm Design
CMIS 102 is UMGC's entry point to programming, teaching problem decomposition, algorithm design, and basic coding in Python. It's the prerequisite gateway for the computer science and software development paths, and weekly work centers on small programming exercises that build from sequential logic to functions and loops.
CMIS 111: Social Networking and Cybersecurity Best Practices
CMIS 111 is a hands-on survey of social networking platforms and personal cybersecurity: how to use professional and personal networks while protecting yourself from common attacks. It's a popular general-education technology elective with projects built around real accounts and security tools rather than exams.
CMIS 242: Intermediate Programming
CMIS 242 is UMGC's object-oriented Java course: classes, inheritance, polymorphism, exceptions, generics, and graphical interfaces, assessed through weekly programming projects. It follows the introductory Java course and is where programs stop being scripts and start being designed.
CMIS 320: Relational Database Concepts
CMIS 320 covers relational database theory and practice: the relational model, entity-relationship modeling, normalization, and SQL. Projects walk you from a business scenario to a normalized design to an implemented, queried database, the full design-to-SQL arc in one 8-week session.
