/* Missing Statement ? */
public class foo
{
public static void main(String[]args)throws Exception
{
java.io.PrintWriter out = new java.io.PrintWriter();
new java.io.OutputStreamWriter(System.out,true);
out.println("Hello");
}
}
Answer: Option
Explanation:
The usual method for using/importing the java packages/classes is by using an import statement at the top of your code. However it is possible to explicitly import the specific class that you want to use as you use it which is shown in the code above. The disadvantage of this however is that every time you create a new object you will have to use the class path in the case "java.io" then the class name in the long run leading to a lot more typing.

It doesn't compile for me in NetBeans 6.7.1. It says "cannot find symbol constructor PrintWriter()"

This is totally wrong, there's no constructor for either PrintWriter or OutputStreamWriter and you also need System.out.println unless you have a static import in place.

Hey all!
Its true that here no need to import package but written code is incorrect and there is many way to correct the code.

Static import is needed because you are using out.println() without System.

The statement is incomplete. It should state
java.io.PrintWriter out = new java.io.PrintWriter(new java.io.OutputStreamWriter(System.out), true);
It is to state that the auto flush is on for the PrintWriter that is using as a stream of characters the standard output.
Sorry, I am writing with my mobile phone.
