Core Java Course for Interviews: Zero to Hero
Core Java done right: language foundations, OOP, collections, generics, streams, concurrency basics, and writing clean production code.
About this course
The on-ramp before the advanced Java SSE guide: JVM internals, OOP principles done with real-world-shaped examples, the collections framework, generics, Java 8+ streams and lambdas, concurrency fundamentals, memory and garbage collection, and the habits that separate clean production Java from code that merely compiles. Includes hands-on runnable coding labs with real test cases.
