Question

[Java] I need help completing the method below. The instructions are also below.

public int wordSearch(String word, String filename) {

}

- find the first time the word appears in a text file filename and returns the position of the word in the file(if its the first word in the file, method should return 1)
- assume no punctuation in file
- assume all whitespace is either a new line or single space
- do not include the times that word appears as substring of another word in the file
- if the word is not in file, return -1
- a exception that occurs, return -1

Program

import java.io.FileInputStream;
import java.io.IOException;
import java.util.Scanner;

public class WordSearch {

    public static void main(String[] args) throws IOException
    {
        WordSearch w=new WordSearch();
    Scanner scnr=new Scanner(System.in);
   
    int result;
    String filename="words.txt";
     
    System.out.print("Enter word to search : ");
    String search=scnr.next();
    result=w.wordSearch(search,filename);
    System.out.println(result);
    }
    public int wordSearch(String word, String filename) throws IOException
    {
    FileInputStream fileIn = new FileInputStream(filename);
    String line = "";
    int result=0,i=0;
    Scanner stdin = new Scanner(fileIn);
  
        while(stdin.hasNextLine())
        {
            line = stdin.next();
            result=line.indexOf(word);
            i++;
            if(result==0)
            {
                break;
            }
                     
        }
        stdin.close();
        if(result!=0)
            i=-1;
   return i;
}

}
