Question

Ask the user for the name of a file and a word. Using the FileStats class, show how many lines the file has and how many lines contain the text.

Standard Input	Files in the same directory
romeo-and-juliet.txt the	romeo-and-juliet.txt

Required Output

Enter a filename\n
romeo-and-juliet.txt has 5268 lines\n
Enter some text\n
1137 line(s) contain "the"\n

Your Program's Output

Enter a filename\n
romeo-and-juliet.txt has 5268 lines\n
Enter some text\n
553 line(s) contain "the"\n
 (Your output is too short.)

My Code:

import java.util.Scanner;
import java.io.BufferedReader;
import java.io.File;
import java.io.FileReader;
public class FileStats
{
    public static void main(String[] args) throws Exception
    {
        Scanner input=new Scanner(System.in);
        System.out.println("Enter a filename");
        String file_name=input.nextLine();


        int word_line_count=0,line_count=0;
        String search_word=input.nextLine();
        File f=new File(file_name);
        String[] words_sentence;
        FileReader file_object = new FileReader(file_name);
        BufferedReader buffer = new BufferedReader(file_object);
        String sentence;

        while((sentence=buffer.readLine())!=null)
        {
            words_sentence=sentence.split(" ");
            for (String word : words_sentence)
            {
                if (word.equals(search_word))
                {
                    word_line_count++;
                    break;
                }
            }
            line_count++;
        }

        System.out.println(file_name + " has " + line_count + " lines");

        System.out.println("Enter some text");

        System.out.println(word_line_count + " line(s) contain " + '\u0022' + search_word + '\u0022');
        file_object.close();
    }
}
