Which of the following lines can be inserted at line 1 to make the program run? //line 1

public class TestClass{   
public static void main(String[] args){
     PrintWriter pw = new PrintWriter(System.out);
     OutputStreamWriter osw  =  new OutputStreamWriter( System.out );
     pw.print("hello");   
}
}

Assume that PrintWriter and OutputStreamWriter are valid classes in java.io package.
Enthuware answer say option 3 is correct answer, but when i put this code, it needs both option 2 & 3 to compile this code without error. (import java.io.*; and also import java.io.OutputStreamWriter;)

I was given following options

1) import java.lang.*;
2) import java.io.*;
3) import java.io.OutputStreamWriter;
4) include java.io.*;
5) include java.lang.System;

I see that option 2 i.e. import java.io.* is marked as the correct option. If you have already imported java.io.*; you shouldn't need to import java.io.OutputStreamWriter; because OutputStreamWriter is a member of java.io package.

Thanks for your response. Does that mean answer from the test is wrong ? As you mentioned, even i select import java.io.*;
Probably you need to update the question bank.
Thanks

No, what I mean to say is that the correct option set in the question bank for this question is option 2. Option 3 is not set as the correct answer. In other words, the question bank is correct.
