Question

Which class can be used to read data into a text file?

Answer 1

Answer:

BufferedReader

Explanation:

There are many ways for reading a file. Many classes independently or with combination can be used for this purpose.

Option (a) BufferedReader class can be used to read data of a file.

Option (b) The System class contains methods which are useful to conduct IO ( Input Output ) operations like Standard Input and Standard Output.This class cannot be used to read a file. So, option (b) is not correct answer.

Option (c) and (d) Even though the names ReadFile and FileRead seems to be classes related to reading a file but there are no classes with the names ReadFile and FileRead. Infact there is a class named "FileReader" which can be used to read a file along with "BufferedReader" class. So, options (c) and (d) are not correct answers.
