Read data: I can use classes bufferedReader and bufferwriter.
Lets say I have a text in Java.
I use bufferedReader to read the files if it is a random file
bufferedReader is only the functionality to read a file.
For, Excel files I use the special library, Apache POI library.
These are external libraries.
I use properties class to read the properties files.
Scanner class also for read the data from filesCopyright © 2021 Codeinu
