I'm counting how many times the word "world" occurs in a certain file.
I've tried to ways:
1)
if (words[i].equalsIgnoreCase("world")) count++;if (words[i].contains("world")) count++;package com.codegym.task.task19.task1907;

import java.io.*;
public class Solution {
public static void main(String[] args) throws FileNotFoundException, IOException {
//• The program must read the file name from the console (use BufferedReader).
BufferedReader breader = new BufferedReader(new InputStreamReader(System.in));
String fName = breader.readLine();
//String fName = "C:\\Users\\passe\\Documents\\Input.txt";
//• The BufferedReader used for reading input from the console must be closed after use.
breader.close();
//• The program must read the file's contents
// (use the FileReader constructor that takes a String argument).
FileReader freader = new FileReader(fName);
int count = 0;
//• The file input stream (FileReader) must be closed.
BufferedReader fBreader = new BufferedReader(freader);
String line = null;
while ((line = fBreader.readLine()) != null) {
//• The program must output to the console
// the number of times the word "world" appears in the file.
String[] words = line.split("[!._,'@?//s]");
for (int i = 0; i < words.length; i++) {
if (words[i].equalsIgnoreCase("world")) count++;
}
}
freader.close();
fBreader.close();
System.out.println(count);
}
}
