Join Ketkee Aryamane for an in-depth discussion in this video ExecutorService overview, part of Java EE: Concurrency and Multithreading.
- [Instructor] Let's take a look…at the Executor Service Demo that you're going to execute.…Now, this is going to be a little longer demo,…so I'll request you to be patient with it.…Let's first understand what we are going to do.…We are going to implement a use case.…That use case is that we want to process users information.…What are we going to do as a part of this use case?…We are going to the read, then enter user information…from a file.…I'll show you the file in a minute.…And, once you read the user information,…you're going to process and then you're going to insert…a record for each user in the database.…
The file of the user information will look like this.…It's available for you in your exercise files…under 03_04, which is this (mumbles).…You have the email,…you have the name of the person,…and then the ID.…Right?…And, you have many such users in this file.…So, what we're going to do is read this file,…read every line.…Every line represents one user record.…Right?…So, we take that user record, we process it.…
