Core Java - Multithreading and Classes

LearnKartS focuses on concurrency and frequently used language classes. Thread creation and synchronization share the roughly three-hour syllabus with wrappers, immutable strings and string-building utilities. It is a targeted continuation after core object-oriented Java.

What you will learn

• Follow a thread’s lifecycle and identify shared-state concerns.
• Use wrappers and understand boxing conversions.
• Compare immutable strings with mutable string-building operations.

Who this suits

Learners who already understand Java classes, objects, methods, inheritance and polymorphism.

Before you enroll

The provider lists those core concepts as prerequisites and marks the course intermediate. Short examples still need repeated execution and tests to reveal concurrency problems.

Coursera offers paid enrollment or subscription access. Check the enrollment screen for assessment and certificate terms, trials and any financial-aid options. Tool subscriptions, model API usage and cloud services may cost extra.

Put it into practice

Create a shared counter and demonstrate a lost update with concurrent access. Add synchronization and explain the trade-off before treating the result as correct.
