1. what is the correct format of reading a line of
String objects ?
a) FileInputStream fis = new
FileInputStream("Filename.txt");
b) DataInputStream dis = new DataInputStream(new
FileInputSTream("FileName.txt"));
c) DataInputStream dis = new DataInputStream(new
FileInputSTream("FileName.txt"), "r");
I think it's a,b
please reply.

Janani,
Answer c is no doubt wrong because of its syntax. it holds good
only a RandomAccess file.
Answer a is also wrong because there is no method by which u can
read a line using the FileInputStream. It can only read bytes of
data rather than in terms of Strings or chars or primitives.
Answer b is the correct answer.
The question is which of the following correctly reads a LINE of
String objects.
Hope this helps.

IMHO, none of them would work...
The case of the FileInputStream() method in (b) is incorrect (there's no upper-case T in the method name):
DataInputStream dis = new DataInputStream(new FileInputSTream("FileName.txt"));
Call me Mr Picky Pedant, but the exam does call for exactitude.
