Thanks for teaching what our mediocre educational system cannot despite having the audacity of charging what it costs.
-
what does close function do
-
I can add records with an input??
-
How can I have the user input the records to the file?
-
I have a little problem with this method. It rewrites the text file each time I launch the program! How to solve this problem?
-
Is this all defunct since Java 8 came onto the scene?
-
Enjoying not following the class naming conventions set by Oracle, huh? 😛
-
Why is bucky trying to handle exceptions? When will you get an error while create a file?
-
This videos have helped me understand java as they are more practical and easy to understand plus the clarity is good.
-
I try to run this and it says "Error: Main method not found in class"
-
How would you write to the same file but not overide it. Ex: a contact book that when you ran the program you could choose to either add to an existing contact list or search that file for existing contacts.

nice toturials

What's the point of the catch in this scenario?
If there's no file with filename "Fred.txt" in the location I'm creating in, it lets me create "Fred.txt"
If there already is "Fred.txt" in location, it still lets me create a new "Fred.txt"
When would the catch part of the try…catch actually get executed? -
This was easy and iteresting.
-
Its not letting me add more than one piece of data to the file. For example, if I do, x.format("Bob", "Alex, "Charlie); it only shows Bob in the file. I have to x.format(one piece of data) every time does anyone know whats going on? Help pls
-
what is an x? a build-in object?
-
Just pointing it out there, you can run the code in one class instead of making a second "main" class, by adding: public static main void (String[] args) { "Insert Stuff"} right before the last parenthesis (that signals the end of class).
-
How do I overwrite existing data in the file?
-
Ιf I wanted to write something else inside this file, like new information or smth, how would i do it? Could i declare a new value maybe y and do the following: (in their corresponding blocks)
y = new Formatter("chinese.txt"); //so that it can add to the file without creating it again
y.format(~~~whatever~~~);
y.close(); -
String.format() isn't supporting in my java. how we can fix it??
-
When you have Avenging to do but also have to teach programming 😀 that's BUCKY :3
-
you should create a program that tracks down who dislikes your videos so I can beat their ass
-
Interestingly, for the Formatter class, the command n doesn't work as with String.format(). Instead use %n.
