Java Program to count the number of words present in a file

//count the number of words present in a text file 

 import java.io.BufferedReader;  
 import java.io.FileReader;  
   
 public class CountNoOfWords
 {  
    public static void main(String[] args) throws Exception 
    {  
    String str;  
    int count = 0;  

    //file in read mode  
    FileReader f = new FileReader("inputInfo.txt ");  
    BufferedReader br = new BufferedReader(f);  

  
    while((str= br.readLine()) != null) 
    {  
      //Splits into words  
      String words[] = str.split(""); 

      //Counts each word  
      count = count + words.length;  

    }  

    System.out.println("Number of words present in given file: " + count);  
    br.close();  
    }  
 }

Output:

Number of words present in given file: 72
