Your opinion. What is the best input method?

Question

Java

I am learning to write in Java. I enter data from the keyboard using Scanner, today my classmate said that he uses some kind of "buffer", and said that he seems to be the best.
And then it became interesting to me, which input method is the best in your opinion, what do you use?

Answer 1

Answer: none.
In Java, console input is almost never used and is offered for study only for educational purposes.
About the buffer:
It looks like this

BufferedReader reader = new BufferedReader(new InputStreamReader(System.in));
String s = reader.readLine();

I like this option (with a buffer) more: for input from a file, the difference will be small (for text):

BufferedReader reader = new BufferedReader(new FileReader("input.txt"));
String s = reader.readLine();

Answer 2

The best one is the one that is better suited for this task, a classmate tells you nonsense, usually it doesn’t matter at all, so I use the one that comes to hand.

Answer 3

Use bufferedreader to come in handy later
