Reading from a CSV File and Searching for a Record in Java

Reading from a CSV File and Searching for a Record in Java

Hello guys, I'm back with another file handling video and today we will be killing 2 birds with one stone by allowing the user to search for a record via reading the file, if it is found then tell the user the record details, if not found then tell them the record can't be found. This is in my opinion the hardest thing to dofor the As Practical exam but watch this video and practice in a couple of scenarios and you will be a pro. Thanks for being a great audience and we will see you next time!

Easter holidays are over but I will try to upload as often as possible. Why not subscribe to keep notified when I upload?

great tutorial and detailed explanation for each line. I t helps me understand what everything is doing and what I need to do in a project ive got.
What did confuse me a little was when you explained the conditions of the while loop and said that !found means 'is found', but I eventually knew what you meant was that the while loop will continue until 'found' is found to be true. thank you again, glad I found your tutorials, Ive subscribed on just this vid, cheers mate.

Thank you so much I implemented this for a button and it works so nice. the buttons reads, retrieves, adds to JTable and writes to another file

Great clear video!
If I wanted to add a list of items and move items from a file would this be the right approach? or would xml using JSP be better?
Thanks

Great video ! You should replace your if(ID.equals(searchTerm)) { found = true; } by found = ID.equals(searchTerm); tho

Hello! How to make this into dynamic? I mean the user will input the search term into the console then it will display the result.

In the line of x = new scanner, I am getting error of differ in length, please help

[akanshyadash]

Hello sir, i am getting false in x.hasNext, so my fn is not working...how should I proceed?

[khisa]

Instead of writing a string in the searchterm what if i were to take that as user input? I am using system.in to take the input but idk what to do with it. Thanks

hey can you tell me how to use CSV parser ? for editing the csv files

[marial]

I followed the tutorial and it continues to not work. I might need some help.

[ahmadalghizi]

for the filepath, did you drag the tutorial.txt into the project folder or did you get the filepath from where u had it stored in your computer since i keep getting an error?

[MrJona]

Is there any way to make this function more efficient if you are only checking for one value like in this example. Instead of going through each item, just check if one item in a row is equal. In other words do you have to write x.next(); to go through each value or could you skip some of the values? How would that impact the performance?
(I have to search through a large database with thousands of rows and around ten or so columns)

[ahmadalghizi]

what if instead of having 3 paramters in my text file i have 4 or 6 or 8, is there a way to make this have a lower coupling?

Hi, do you know how we would do this in JavaFX? Thanks.

[aadilmufti]

Great Video! Just a quick question, what if the CSV file has headers, how do I parse through it without considering the catagories within the file? Thank You!
