Java 21+ Core Fundamentals & Object-Oriented Architecture Dasar-Dasar Java 21+ & Arsitektur Berorientasi Objek

A comprehensive hands-on curriculum from zero to confident Java programmer. Master modern Java 21+ primitives, control flow, object-oriented design (encapsulation, inheritance, polymorphism, abstraction), interfaces, custom exceptions, and real-time unit test verification. Kurikulum langsung yang komprehensif dari nol hingga menjadi programmer Java yang andal. Kuasai tipe data primitif Java 21+, alur kontrol, desain berorientasi objek (enkapsulasi, pewarisan, polimorfisme, abstraksi), antarmuka, custom exception, dan verifikasi unit test real-time.
