This Java programming lecture covered fundamental concepts starting with *primitive data types* versus objects, explaining how primitives differ from their corresponding wrapper classes. The instructor explained type systems in Java, highlighting that class names begin with capital letters while primitive types use lowercase. The session introduced the *'var' keyword* (added in Java 10) for type inference, discussing its capabilities and limitations in variable declarations. The lecture then covered *type conversion* concepts, distinguishing between widening (implicit) and narrowing (explicit) conversions with practical examples. The final portion addressed Java **operators**, categorizing them as unary, binary, and ternary, with special emphasis on increment/decrement operators and their pre/post variations, noting their importance in technical interviews.
