.
Which can be used to accept charS from input.
1. java.io.CharArrayReader
2. java.io.InputStreamReader
3. java.io.OutputStreamReader
4. java.io.FileReader.
I was confused by the use of charS , which was not shown as primitive type or an object reference.
Question is just this much. I answered it as java.io.InputStreamReader and hope I got it wrong.
Do u have any clue ?

Hi Binu,
I think the question meant 'chars' as 'characters'. Anyway, option (2) is correct, assuming what it meant by 'input' is standard input (System.in).
Btw, I think you mean 'hope I got it right

Hi,
I think option 1 is right. The question only asks for a class which could accept charS from input. If the "charS" denotes characters, it means those classes which could take in characters as input. Option 1, ie. CharArrayReader does exactly the explained scenario by accepting a char[] as input. If multiple answers are expected, I will prefer to choose 1,2 and 4, because all these Readers could be used for reading characters. But if this question demands single answer, I would prefer to adhere to option 1.
regards Jacob
