import java.nio.file.*;
import java.io.*;
public class ReadFile
{
public static void main(String[] args)
{
Path file = Paths.get("C:\\Java\\Input.Output\\Grades.txt");
InputStream input = null;
try
{
__________________________________________
__________________________________________
String grade = null;
grade = reader.readLine();
System.out.println(grade);
input.close();
}
catch (IOException e)
{
System.out.println(e);
}
}
}
In the code above, a ReadFile class reads from the Grades.txt file. A path is declared, and an InputStream is declared using the Path. In the first shaded line, create the statement to assign a stream to the InputStream reference. In the second shaded line, declare a BufferedReader that reads a line of text from a character-input stream that buffers characters for more efficient reading.
