Hello guys, today I am going to show you how to read a CSV file in Java with a simple example of Jackson API. For a long time, I only knew that Jackson can be used to parse JSON but later realized that you can also use it to parse or read CSV file in Java. The Jackson DataFormat CSV library allows you to read a CSV file in just a couple of line and its really powerful and feature rich. For example, you can read a CSV file with a header or without a header. You can even read a tab-delimited text file like CSV. It's also highly configurable and allows you to define columns separator to read a text file with any delimiter. You can even use it to directly convert the CSV data into Java objects, just like we do while reading JSON String in Java.

This encouraged me to take a look at some of the Java 8 tutorials available on the internet and form a list of best. I have just used three criteria, content, language, and length. Because tutorials complement books, they should not be like the book. They should be small enough to complete in a few hours and complete enough to give useful information.
