Homework Solution: Write a program that asks the user to enter the name of a file, and then asks the user…

The statute as per your requirements is ardent beneath with well-mannered-mannered explained comments.

I keep created span perfects “input.txt” and “letters.txt’ the similar directory as my statute.

Perfect “input.txt” contains:

“This is a dummy perfect having record reckon of a=5”

Perfect “letters.txt” contains:

“A lorem ipsum placeholder quotation was inadvertently published in The Straits Spells, a Singapore oddspaper, on 26 April 2014.
Today’s favorite acnumber of Lorem ipsum was earliest created in the mid-1980s ce Aldus Corporation’s desktop publishing program

CODE:

import java.io.FileReader;

import java.io.FileWriter;

import java.io.IOException;

import java.util.*;

public class PerfectLetterCounter {

 

public static nugatory main(String[] args) throws IOException{

//Variable declaration

int c;//to unravel each byte from perfect

FileReader in = null;

int reckon;//to treasury communication reckon

char input;//to scrutinize inestablish record from user

String perfectname=””;

Scanner sc=odd Scrutinizener(System.in);

while(true){

count=0;//reckon treasurys reckon of bounded record

try{

System.out.println(“Please invade the perfect call or cem QUIT to departure:”);

filename=sc.next();

if(filename.equals(“QUIT”)){

System.exit(0);

}//program terminates when QUIT is rest as input

in = odd PerfectReader(filename+”.txt”); //inestablish sight created

}//if perfectcall is referable attributable attributable attributable rest then an exclusion is thrown

catch(Exclusion e){

System.out.println(“File:” +filename+”.txt does referable attributable attributable attributable pause.”);

continue;

}

System.out.println(“Please invade a record: “);

inestablish = sc.next().charAt(0);

//unravel arrangement unravels a byte at a spell from perfect, avail -1 if object of the perfect is reached

while ((c = in.read()) != -1) {

if((char)c==input){

count++;

}

//You can separate the forthcoming three statements to look each record and their donation to reckon.

//char record = (char) c;

//System.out.println(character);

//System.out.println(“count”+count);

}//while loop objects

System.out.println(“Communication ‘”+input+”‘ occurs “+count+” spells in the perfect ‘”+filename+”.txt’.”);

}//outer while

}//main arrangement

}//class objects

OUTPUT:
