Concurrency

Choose a goal, then follow each stage as an ordered, explained outline.

Learning goal

Learn deeply

Build a durable mental model, then transfer it into a working application.

Foundation

Stage purpose: Establish the vocabulary and first working mental model.

Required background: Complete the linked prerequisites below or bring equivalent experience.

Expected outcome: Explain the core idea and use it in a small example.

Estimated time: 30 minutes

  1. Lesson · Estimated time: 30 minutes

    Intro to Threads

    Outcomes
    • Explain the core idea in Intro to Threads
    • Apply Intro to Threads in a representative exercise

    Prerequisites: No prerequisite topics

    Evidence: Practise the outcome in code and record what you learned.

    Current status: Not started

    Recommended next: Thread Synchronization — Carry the Intro to Threads mental model into the next step with a concrete transfer exercise.

Core concepts

Stage purpose: Connect the concepts into a repeatable problem-solving model.

Required background: Complete the linked prerequisites below or bring equivalent experience.

Expected outcome: Apply the model to a representative exercise without copying a recipe.

Estimated time: 30 minutes

  1. Lesson · Estimated time: 30 minutes

    Thread Synchronization

    Outcomes
    • Explain the core idea in Thread Synchronization
    • Apply Thread Synchronization in a representative exercise

    Prerequisites: Intro to Threads

    Evidence: Practise the outcome in code and record what you learned.

    Current status: Not started

    Recommended next: Thread Pools & ExecutorService — Carry the Thread Synchronization mental model into the next step with a concrete transfer exercise.

Applied transfer

Stage purpose: Transfer the concepts into a realistic implementation task.

Required background: Complete the linked prerequisites below or bring equivalent experience.

Expected outcome: Produce a small artifact that proves the decision works.

Estimated time: 30 minutes
