Java Program Get a Line With Max Word Count From the Given File

Java Program: 

Write a program to get a line with max word count from the given file?

Description:

Below example shows how to find out the line with maximum number of word count in the given file. In case if it has multiple lines with max number of words, then it has to list all those lines.

Code:

package com.java2novice.algos;

import java.io.BufferedReader;
import java.io.DataInputStream;
import java.io.FileInputStream;
import java.io.FileNotFoundException;
import java.io.IOException;
import java.io.InputStreamReader;
import java.util.ArrayList;
import java.util.List;

public class MaxWordCountInLine {

    private int currentMaxCount = 0;
    private List<String> lines = new ArrayList<String>();
    
    public void readMaxLineCount(String fileName){

        FileInputStream fis = null;
        DataInputStream dis = null;
        BufferedReader br = null;
        
        try {
            fis = new FileInputStream(fileName);
            dis = new DataInputStream(fis);
            br = new BufferedReader(new InputStreamReader(dis));
            String line = null;
            while((line = br.readLine()) != null){
                
                int count = (line.split("\\s+")).length;
                if(count > currentMaxCount){
                    lines.clear();
                    lines.add(line);
                    currentMaxCount = count;
                } else if(count == currentMaxCount){
                    lines.add(line);
                }
            }
        } catch (FileNotFoundException e) {
            e.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
        } finally{
            try{
                if(br != null) br.close();
            }catch(Exception ex){}
        }
    }

    public int getCurrentMaxCount() {
        return currentMaxCount;
    }

    public void setCurrentMaxCount(int currentMaxCount) {
        this.currentMaxCount = currentMaxCount;
    }

    public List<String> getLines() {
        return lines;
    }

    public void setLines(List<String> lines) {
        this.lines = lines;
    }
    
    public static void main(String a[]){
        
        MaxWordCountInLine mdc = new MaxWordCountInLine();
        mdc.readMaxLineCount("/Users/ngootooru/MyTestFile.txt");
        System.out.println("Max number of words in a line is: "+mdc.getCurrentMaxCount());
        System.out.println("Line with max word count:");
        List<String> lines = mdc.getLines();
        for(String l:lines){
            System.out.println(l);
        }
    }
}

true, false, and null might seem like keywords, but they are actually literals.
You cannot use them as identifiers in your programs. The servlet context
is an interface which helps to communicate with other servlets. It contains
information about the Web application and container. It is kind of
application environment. Using the context, a servlet can obtain URL
references to resources, and store attributes that other servlets in the
context can use.

Output:

Max number of words in a line is: 13
Line with max word count:
true, false, and null might seem like keywords, but they are actually literals.
