What does this line mean!

Question

FileOperations.writeToFile(new BusinessAccount());

FileOperations and businessAccount are classes i knw that. I am just confused what the above line actually do!

Answer 1

It just means that you can write objects to a file as well and transfer it. Other ways could be using sockets or queues etc.

Answer 2

FileOperations is a class which has a writeToFile() method and it takes a BusinessAccount object as parameter.

Answer 3

ObjectOutputStream is a class which is generally used to write objects to a stream, it could be a file as well.

The above line just creates a reference of ObjectOutputStream and assigns null to it.
