Chapter 6, Problem 9E

Explanation of Solution

Program code:

Main.java

//import the required packages

import java.io.File;

import java.io.FileNotFoundException;

import java.util.Scanner;

//define a class Main

public class Main

{

//define a method wordWrap()

public static void wordWrap(Scanner Input)

{

//create a string variable line

String line;

    //iterate a while loop

while(Input.hasNextLine())

{

//read the line

line=Input.nextLine();

//iterate a while loop

while (line.length() > 60)

{

//create substring of length 60

System.out.println(line.substring(0, 60));

line = line.substring(60);

}

//print the line

System.out.println(line);

}

    }

//define the main() method

public static void main(String args[])throws FileNotFoundException

{

    //create an object of Scanner

    Scanner Input=new Scanner(new File("file.txt"));

    //call the method wordWrap()

    wordWrap(Input);

    }

}
