Java Program to find the most repeated word in a text file

In this example, we will create a java program to find the most repeated word present in given text file.

Program:


import java.io.BufferedReader;    
import java.io.FileReader;    
import java.util.ArrayList;    
     
public class Main 
{    
        
    public static void main(String[] args) throws Exception 
	{    
        String line, word = "";    
        int count = 0, maxCount = 0;    
        ArrayList<String> words = new ArrayList<String>();    
            
        FileReader file = new FileReader("example.txt ");    
        BufferedReader br = new BufferedReader(file);    
            
        while((line = br.readLine()) != null) 
		{    
            String string[] = line.toLowerCase().split("([,.\\s]+) ");    
            for(String s : string){    
                words.add(s);    
            }    
        }    

        for(int i = 0; i < words.size(); i++)
		{    
            count = 1;    
            for(int j = i+1; j < words.size(); j++)
			{    
                if(words.get(i).equals(words.get(j)))
				{    
                    count++;    
                }     
            }    
            if(count > maxCount)
			{    
                maxCount = count;    
                word = words.get(i);    
            }    
        }    
            
        System.out.println("Most repeated word: " + word);    
        br.close();    
    }    
}

Output
Most repeated word: PHP
