This deck covers the core building blocks of Java programming, from understanding the runtime environment (the JVM, JDK, and JRE) to the foundational concepts of object-oriented programming. You'll work through the four pillars of OOP — encapsulation, inheritance, polymorphism, and abstraction — along with practical language features like constructors, access modifiers, the static and final keywords, method overloading and overriding, and how abstract classes differ from interfaces.
It's a great fit if you're just starting out with Java and want a clear, structured way to learn the essentials, or if you're preparing for a technical interview and need to refresh key definitions and distinctions. Intermediate learners returning to Java after time away will also find it useful for tightening up terminology and filling in gaps in their understanding of how the language is organized.
To get the most out of these cards, try working through a small batch at a time rather than tackling everything in one sitting. Since many of the concepts build on each other — like understanding access modifiers before diving into encapsulation, or grasping overloading before overriding — reviewing earlier topics briefly before moving forward will help the later material click into place. Mixing in some hands-on coding alongside the flashcards is a great way to reinforce what you're learning.
