Answer 2

First import java.io.*; and java.util.*;
than there are so many build-in class that can do the jobs .But if you are to use Scanner class than you can easily do the work..for that

In the main class
Scanner in = new Scanner(new FileReader("text.in"));

//take the file that should be located in the same directory otherwise put location of path like ("c://home/Documents") ....//

BufferedWriter inp = new BufferedWriter(new FileWriter("textout.txt"));
In scanner class there are so many methods
in.next()//read by character
in.hasNext();
in.nextLine();read line by line...
