Explanation of Solution
Program code:
Main.java
//import the required packages
import java.io.File;
import java.util.Arrays;
import java.util.Scanner;
//define a class inputStats
public class Main
{
//define the main
public static void main(String[] args) throws Exception
{
//create the object of File class
File fileName = new File("carroll.txt");
//create the object of Scanner class to refer the file
Scanner input = new Scanner(fileName);
//call the method mostCommonNames()
inputStats(input);
}
//define the method inputStats()
public static void inputStats(Scanner input)
{
//declare integer variables
int lineNum=0;
int longestLine=0;
//declare string variable
String longestString="";
//iterate a while loop to get the lines of the file
while(input.hasNextLine())
{
//increment the lineNum by 1
lineNum++;
//get the lines to the variable line
String line=input.nextLine();
//condition for checking the length of the line
if(line.length()>longestLine)
{
//length of the line is assigned to the variable
longestLine=line.length();
//set the value of longestString as line
longestString=line;
}
//create two integer variables
int token=0;
int longest=0;
//create a variable of Scanner class
Scanner console=new Scanner (line);
//iterate a while loop to get the tokens
while(console.hasNext())
{
//increment the value of token by 1
token++;
//get each words to word
String word=console.next();
//if the length of the word is greater than longest
if(word.length()>longest)
{
//set the length of the word to variable longest
longest=word.length();
}
}
//print the values
System.out.printf("Line %d has %d tokens (longest = %d)\n", lineNum, token, longest);
}
//print the longest string
System.out.println("Longest line: "+longestString);
}
}

Beware the Jabberwock, my son,
the jaws that bite, the claws that catch,
Beware the JubJub bird and shun
