Reading a very huge file in java

Question

I was asked in an interview how to read a very huge file ,the situation was suppose i have the ram size is 2GB but the file i need to read is of 5GB how this can be done effectively in java , i have searched on Google most of the solutions is to use buffered Reader . Can any body help me

public class BufferedReaderExample {

public static void main(String[] args) {

    try (BufferedReader br = new BufferedReader(new FileReader("C:\\testing.txt")))
    {

        String sCurrentLine;

        while ((sCurrentLine = br.readLine()) != null) {
            System.out.println(sCurrentLine);
        }

    } catch (IOException e) {
        e.printStackTrace();
    } 

}
}

Will this be effective or java provide some other in build functionality to do this
