Java Program to find the number of the words in the given text file

In this program, we need to find the most repeated word present in given text file. This can be done by opening a file in read mode using file pointer. Read the file line by line. Split a line at a time and store in an array. Iterate through the array and count the word. The content of data.txt file used in the program is shown below.

data.txt

A computer program is a collection of instructions that performs specific task when executed by a computer.

Computer requires programs to function.

Computer program is usually written by a computer programmer in programming language.

A collection of computer programs, libraries, and related data are referred to as software.

Computer programs may be categorized along functional lines, such as application software and system software.

Algorithm

STEP 1: START
STEP 2: DEFINE String line
STEP 3: SET count =0
STEP 4: USE File Reader to open file in read mode.
STEP 5: READ line from file
STEP 6: REPEAT STEP 7 to STEP 8 UNTIL reach the end of file
STEP 7: SPLIT lines into words and STORE in array string words[].
STEP 8: count = count + words.length
STEP 9: PRINT count.
STEP 10: END

import java.io.BufferedReader; import java.io.FileReader; public class CountWordFile { public static void main(String[] args) throws Exception { String line; int count = 0; //Opens a file in read mode FileReader file = new FileReader("data.txt "); BufferedReader br = new BufferedReader(file); //Gets each line till end of file is reached while((line = br.readLine()) != null) { //Splits each line into words String words[] = line.split(""); //Counts each word count = count + words.length; } System.out.println("Number of words present in given file: " + count); br.close(); } }
