Question

Submit Chapter6.java with a public static method named justifyText that accepts two parameters; a Scannerrepresenting a file as the first parameter, and an int width specifying the output text width. Your method writes the text file contents to the console in full justification form.

. For example, if a Scanner is reading an input file c ). For example, if a Scanner is reading an input file containing the following text: Four seven fathers brought score and years ago our forth on this continent new nation. Then a call to justifyText(input, 30 will output the following to the console: Four score and seven years ago our fathers brought forth on this continent a new nation.

Explanation / Answer

/**The java program Chapter6 that opens a input file "input.txt"
* file and calls the metod justifyText and prints
* the words from the text of a width 30*/
//Chapter6.java
import java.io.File;
import java.io.FileNotFoundException;
import java.util.Scanner;
public class Chapter6
{
   public static void main(String[] args)
   {
       Scanner scanner=null;
       final int width=30;
       try
       {
           //open an input text file "input.txt"
           scanner=new Scanner(new File("input.txt"));
           //calling justifyText method
           justifyText(scanner, width);
       }
       catch (FileNotFoundException e)
       {
           System.out.println(e);
       }

   }

   /**The method justifyText takes an input parameters
   * Scanner object and widht and then prints text line of widht
   * 30*/
   public static void justifyText(Scanner scanner, int width)
   {
      
       //set variables to intial variables
       int totalSize=0;
       int wordCount=0;
       int spaceCount=1;
       String word=scanner.next();
       while(scanner.hasNext())
       {          
           //count total word size
           wordCount+=word.length();
           //count total spaces
           spaceCount++;
           //calcualte totalSize
           totalSize=wordCount+spaceCount;
          
           //Check if totalSize is greater than or equalt to width
           //reset the word ,space and total size variables
           if(totalSize==width)
           {              
               //print a new line and
               System.out.println();
               System.out.printf("%s ",word);
               //reset
               wordCount=0;
               spaceCount=0;
               totalSize=0;
           }
           else if(totalSize>=width)
           {
               //print a word
               System.out.printf("%s ",word);
               //print a new line
               System.out.println();
               //reset
               wordCount=0;
               spaceCount=0;
               totalSize=0;
           }
           else
               //print the word to console
               System.out.printf("%s ",word);
          
           word=scanner.next();
       }  
       System.out.printf("%s",word);
