You are to write a program that reads the text of a book on the web and counts the number of times a particular word occurs in the book. Your program should first ask the user for the complete Universal Resource Locator (URL) or link of a file on a website. Typically the user would find it easiest to copy the link at the top of their web browser and paste it as input to your program. Your program should then ask for the word to be searched. The programs output will give the number of times the word appears in the text of the file. You will want to create a java.net.URL object and use that to create a Scanner object to read from the website one line at a time using readLine(). To avoid complications with upper and lower-case characters, your program should convert the user’s input word to lower case and convert all of the input file text to lower case. This will ensure the program finds the words regardless of case.

import java.util.Scanner;
public class cheggBannedBook{
public static void main(String []arg) throws Exception{
Scanner scn = new Scanner(System.in);//for input
System.out.println("Please enter URL");
String urlAddress = scn.next();
URL url = new URL(urlAddress);
System.out.println("Please enter word to be searched");
String word = scn.next();
word = word.toLowerCase();
Scanner urlFile= new Scanner(url.openStream());//to read file content from URL

int count = 0;
while(urlFile.hasNext()){
String line = urlFile.nextLine();
String []words = line.split("\s");//split line on the basis of whitespace in the line
for(String wrd : words){
if((wrd.toLowerCase()).equals(word)){
count++;
}
}
}
System.out.println("Total occurance of "+ word + " is "+ count);
