Overview

Java collections, data structures, and object-oriented programming alongside architecture notes and model evaluations.

Archive brings together Java study references and working notes outside the dedicated cloud, AI, and database tracks. The Java sections cover collections, data structures and algorithms, and object-oriented programming; general notes cover application architecture and model evaluations.

General

Jev Decision Model

Architecture, cost economics, calibrated confidence, and execution mechanics of non-autoregressive decision models.

Architecture Patterns

UI patterns, application layering, folder grouping styles, and monorepo architectures for TypeScript and Python.

Java

Collections

Arrays, strings, lists, queues, sets, and maps, with implementation details, API references, and complexity comparisons.

DSA

Linked lists, trees, algorithmic complexity, and problem-solving patterns with Java implementations and exam practice.

OOPs

Encapsulation, abstraction, inheritance, and polymorphism, including Java method dispatch and overriding rules.
