A file named 'input.txt' contains a list of words. Write a program that reads the content of the file one word at a time. Check

Margarita [4]

Answer:

// here is code in java.

import java.io.*;

import java.util.Scanner;

class Main{

// function to check a word is palindrome or not

private static boolean is_Palind(String str1)

{

// if length of String is 0 or 1

if(str1.length() == 0 || str1.length() == 1)

{

return true;

}

else

{

// recursively check the word is palindrome or not

if(str1.charAt(0) == str1.charAt(str1.length()-1))

{

return is_Palind(str1.substring(1,str1.length()-1));

}

else

{

return false;

}

// driver function

public static void main(String[] args)

{// variable to store word

String word;

// BufferedWriter object

BufferedWriter buff_w = null;

// FileWriter object

FileWriter file_w = null;

// Scanner object

Scanner sc = null;

try

{

// read the input file name

sc = new Scanner(new File("input.txt"));

// output file

file_w = new FileWriter("output.txt");

// create a buffer in output file

buff_w = new BufferedWriter(file_w);

// read each word of input file

while(sc.hasNext())

{

word = sc.next();

// check word is palindrome or not

if(is_Palind(word))

{

// if word is palindrome then write it in the output file

buff_w.write(word);

buff_w.write("\n");

}

// close the buffer

buff_w.close();

// close the input file

sc.close();

}

// if there is any file missing

catch (FileNotFoundException e) {

System.out.println("not able to read file:");

}

// catch other Exception

catch (IOException e) {

e.printStackTrace();

}

Explanation:

Create a scanner class object to read the word from "input.txt" file.Read a word from input file and check if it is palindrome or not with the help of is_Palind() function.it will recursively check whether string is palindrome or not. If it is palindrome then it will written in the output.txt file with the help of BufferedWriter object. This will continue for all the word of input file.
