Java File I/O (Reading & Writing)

Hi, may u answer my question, I am just curious about the try catch parts, what do it gonna do? also why do we have to handle that exception as well as what will happen if we just dont handle the exception?

Thanks, was really helpful!😀

Your setup is cool

thanks sir

Do you can solve this:
Build Application that has three classes (three user data types). Every class has
some of attributes and methods to manipulate the objects of these classes.
The objects and their data can be saved permanently into Files. Every class have
to save in three forms of files:
1. Object Stream.
2. Data Stream.
3. Random Access File Stream.
Data can be brought mainly from csv file. Every record consists of multiple fields,
and every line has only one record.

Great video. Many thanks.

Sir, i want to ask you how to create an object like for example Class Student in file io ?

What we should do if we need to edit some information in the saved file without losing the other data?

Append to the file?

Excellent stuff!! You solved my problem in 7 mins.
Also can pls explain how can I limit the number of characters in a particular cell of a csv file. For example upto 2000.
Please help.

how do I send it to a folder that no one else will likely have? I tried making a folder in my C: drive to send it to but no one else will likely have that folder.

Which application have you used for programming in this video?

so buffered readers and writers are restricted to only one functionality (method)?

How do you print out every line in reverse alphabetical order?

nice, thanks for that. However i tried reading from some an excel i created earlier with various columns and rows but i just a lot of binary among other characters. i initially read and wrote to .xls instead of the .txt which worked fine. any ideas?

what str. in bw.write line? even without it will work?

"Beginner". This shit was too hard to follow

is it possible to use this method to make a user password program

Great video man! Keep up the good work

thank you so much! They didn't really explain this at the java lecture, so your video was very helpful!

Which platform do you use?

Amazing video but Is it the same for Mac?

I need this for an application to write its log to a file. Thank you so much!

what is it called with how his bw.write(str:) like it's showing you your method/function is a string. I notice that in all his videos that it tells you what it is.

When My mentor told me we were doing FILE i/o i was kinda scared lmao but it is way easier that what I thought

I wish my assignments were as simple as this 😪

Thanks for the great explanation.

when I wrote backslash, it did not create a new line. Could you clarify me on this problem?
