Question

Trying to practice this assignment

Argument list: the *yahoonews.txt Data file: yahoonews.txt

Write a program named WordCount.java, in this program, implement two static methods as specified below:
   public static int countWord(Sting word, String str)
   this method counts the number of occurrence of the word in the String (str)

   public static int countWord(String word, File file)
  This method counts the number of occurrence of the word in the file. Ignore case in the word. Possible punctuation and symbals in the file include , ! . ; : ? & # and $.

Then test your method with the data file.

This is my code so far and I could use lots of help and explanations to make this work

import java.io.BufferedReader;
import java.io.File;
import java.io.FileReader;
import java.io.IOException;
import java.util.Scanner;

public class WordCount{

   public static void main(String[] args){
      File file = new File(args[0]);
      System.out.println("File name is: "+file);
      String word = "";
             
    
    
    
   }
   public static int countWord(String word, File file){
      int counter =0;
      try{
         BufferedReader b = new BufferedReader(new FileReader(file));
         while((readLine=b.readLine())!=null){
            for(String s: readLine.split(" ")){
               if(s.toLowerCase()==word.toLowerCase()){
                  count++;
             
               }
            }
         }
      
      }catch(IOException e){
         System.out.println("errors");
      }
      System.out.println("count is: " +count);
      return count;


   }


   public static int countWord(String word, String str){
      int count =0;
      Scanner sc = new Scanner(str.toLowerCase());
      word=word.toLowerCase();
      for (int i = 0; i < str.length(); i++) {
         while(sc.hasNext()){
            String temp = sc.hasNext();
            if(temp=="word") count++;
            System.out.println("Current or next line: "+sc.hasNext());
         }
    
      }

      return count;

   }

}

I would like you to modify code as follows:

Instead of taking list of arguments take just filename as argument.

If you need to find the word count from file then the function would be called accordingly.

To get this calculate the no.of arguments.

Also you can take the word whose count is to be found through the argument.

If arguments length is 2 then consider filename is also included otherwise only word is given as argument

Also you need to read the string and pass it as argument to the function but not read it from within the function.

//java code

mport java.io.BufferedReader;
import java.io.File;
import java.io.FileReader;
import java.io.IOException;
import java.util.Scanner;

public class WordCount{

   public static void main(String[] args){

int no_arg = args.length();

if(length==2){
      File file = new File(args[0]);
      System.out.println("File name is: "+file);

      String word = args[1];

System.out.println("The word count is" + countWord(word,file));

}

else

{

String word=args[0];

//read string

StringBuilder everything = new StringBuilder();
    String line;
BufferedReader buffIn = new BufferedReader(System.in);
    while( (line = buffIn.readLine()) != null) {
       everything.append(line);
    }

String str=new String(everything);

System.out.println("The word count is " + wordCount(word,str));
}

             
    
    
    
   }
   public static int countWord(String word, File file){
      int counter =0;
      try{
         BufferedReader b = new BufferedReader(new FileReader(file));
         while((readLine=b.readLine())!=null){
            for(String s: readLine.split(" ")){
               if(s.toLowerCase()==word.toLowerCase()){
                  count++;
             
               }
            }
         }
      
      }catch(IOException e){
         System.out.println("errors");
      }
      System.out.println("count is: " +count);
      return count;


   }


   public static int countWord(String word, String str){
      int count =0;

Scanner sc = new Scanner(str.toLowerCase());
      word=word.toLowerCase();
      for (int i = 0; i < str.length(); i++) {
         while(sc.hasNext()){
            String temp = sc.hasNext();
            if(temp=="word") count++;
            System.out.println("Current or next line: "+sc.hasNext());

    
      }

      return count;

   }

}

As we are taking input as multiple lines we can use simple word count function for string

But you need to replace all \n with " "(space)

static int countOccurences(String str, String word)

{

    // split the string by spaces in a

    String a[] = str.split(" ");

  

    // search for pattern in a

    int count = 0;

    for (int i = 0; i < a.length; i++)

    {

    // if match found increase count

    if (word.equals(a[i]))

        count++;

    }

  

    return count;

}
