What Will I Learn?

• Exploit the ninja techniques learned from this course to write safe and error free multithreading code in the first iteration itself.
• Become confident to move away from the old Threads-API and use the modern Executors-API for all multi-threading needs instead.
• Understand and exploit the various pro techniques to avoid the pitfalls while using Executors.
• Understand and leverage the similarities & differences between the Threads-API and the Executors-API.
• Rightly judge which Executor pool to use for which needs.
• Differentiate between safe and error-prone multi-threading code.
• Appreciate the reasons why Executors API was built even though the Threads API already existed.
• Write efficient multi-threading code by utilizing a plethora of pro tips and techniques.
• Get the Source Code of all the examples!

Requirements

• You should already have a solid grasp of Core Java.
• You should already know about the basic concepts of multi-threading viz. what are threads, why are threads required, various states they can be in, what is synchronization, what is locking, etc.
• You should have Eclipse IDE and JDK 1.7 or higher installed on your machine.
• You should already know how to use Eclipse IDE for Java programming.

Target audience

• This course is meant for all Java professionals who are familiar with Java's Threads-API but who are not comfortable with the Executors-Framework yet. For example - if you know how to terminate normal threads but not how to terminate Executor tasks or threads, then this course is for you.
• Even if you do not know how to terminate normal threads, return values from normal threads and the like - then also this course is for you. Professionals who are still using the old Threads-API and want to have more practical knowledge about some advanced concepts of this API can also benefit from this course as Threads-API is also covered in detail.
• If you love to have deep knowledge of underlying concepts of a technology or topic rather than just shallow familiarity, then this course is for you.
• This course is probably not for you if you are looking to learn about Java multi-threading from scratch!
• This course is definitely not for you if you do not know how to code in Java!
