Hey Koushik, Instead of removing header from the csv file, we can add .linesToSkip(1) inside the reader(){} method.
Thanks.

@Java Brains, Hey Kaushik, the column names are in the input csv file - first row, and we should have simply grabbed it as it is ;) without doing the extra transformation from the Match POJO and stripping off the ceremonies to flatten it, and manually adjusting the camelCase to underscores.

Note: Of course, we haven't used all the columns in our POJO and we need to remove those items specifically - Copy + Paste + Remove a few :).

Thanks Koushik, It's really helps me a lot to understand Spring Batch :) please keep it up. I have a small question why we can't use repository for read and write data into DB ?

[David.Saraiva]

I guess the writer is the only one being injected in the "step1" bean because it requires the bean "dataSource", the reader and processor are not being used by bean injection. Also, I like this kind of series, keep up the good work, I would like to see kotlin instead of java but then the name "javabrains" would sound strange :)

Excellent tutorial Koushik, writer is kept as a argument, (just thinking it loud) might be because object of type DataSource is added by Spring automatically, or we can intervene there as well with plugging specific DataSource object we need.

Do you learn all these different annotations, function names, class names, etc or just copy paste every time ?
Thanks for this wonderful tutorial

for the date issue with csv format, use this formula to convert to standard format
TEXT(G1, "yyyy-mm-dd")

Hi Koushik, can you kindly explain what is a bean in short sentences or share me a video link if you have? I am amateur Java programmer and kinda able to follow this tutorial, but some terms are relatively difficult for me. Thank you!

Duckworth–Lewis–Stern method (DLS) method -> By using this method, the winner will be declared in-case of rain or bad whether conditions in Cricket. In the data csv, the "method" column represents the same.

great video, it got me thinking. Is it possible to read from one database to another using batch in springboot? How?

[mikeli]

do you not need a joblauncher to run the specified job? or it just run automatically once the jobbuilder and stepbuilder has been configured?

[aniket]

Hello Koushik.. Your videos are fantastic.. Is there any plan to create video series on Data structures and on design pattern in future ?

[timefly]

Hey @Koushik, how did you make all the multiple rows into one single comma separated row. How to achieve this in IntelliJ.

[yavuzselimbektas]

Why do we need to create different classes if we do not use the names row in the CSV file?

[amantiwari]

Hey Kaushik, you are doing a great job, a small suggestion Instead of selecting and copying, you can just click on copy button and do the job(3.38).

[yashtiwaritj]

At 4:18, how you opened organize imports using which shortcut key please tell?

Hey Kaushik!

Great Video!

How is the experience of using VSCode for Java?
What are the extensions that you have installed for Java?!

I had tried to use VSCode earlier for java but it was not the best editor for Java at that time.

[saamtech]

What keyboard do you use? love the mechanic sound it makes

[rabinarayansabat]

Hello Sir, I am trying to add junit for this spring batch code but not getting success. Could you please create a video for it or some suggestions.

[ankitdubey]

Hey Kaushik, I want to make an controller which will pass the file to this batch processor but don't know like how should I start it. can you make a video on how this can be done?
