Chapter 6, Problem 11E

Explanation of Solution

Program code:

Main.java

//import the required packages

import java.io.File;

import java.io.FileNotFoundException;

import java.util.Scanner;

import java.io.PrintStream;

//define a class Main

public class Main

{

//define a method wordWrap3

public static void wordWrap3(Scanner input)

{

//iterate a while loop

while (input.hasNextLine())

{

//get the lines of the file

String line = input.nextLine();

//iterate a while loop

while (line.length() > 60)

{

//if the condition is true

if (line.charAt(60) == ' ')

{

//print the substring

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

//create the substring

line = line.substring(61);

}

//if the condition is false

else

{

//omitting the space at the end of a line with size 60

int index = line.substring(0, 60).lastIndexOf(" ");

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

line = line.substring(index + 1);

}

}

//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 wordWrap3()

    wordWrap3(input);

}

}
