Select the correct answerWhich of these class is not related to input and output stream in terms of functioning?OptionsInputStreamWriterFileReader

Break Down the Problem

1. Identify the classes mentioned in the options.
2. Understand the relationship of each class to input and output streams.

Relevant Concepts

• InputStream: A class to read bytes from a source.
• OutputStream: A class to write bytes to a destination.
• InputStreamReader: A bridge from byte streams to character streams.
• FileReader: A class for reading character files.

Analysis and Detail

1. InputStreamWriter: This class is used for writing characters to an output stream by converting them to bytes using a specified character encoding.
2. FileReader: This class is designed to read characters from a file, thus it's related to input functionality specifically.
3. InputStream: This is a generic class for reading bytes and is mostly related to input.

Verify and Summarize

From the analysis, InputStreamWriter and FileReader are related to either input or output functions. The InputStream class, however, focuses solely on reading input streams (bytes) and does not directly deal with the output.

Final Answer

InputStream is not related to input and output stream functioning in the same way as the other two options.
