Question

1. Copy the file secret.txt into a path that you can access. Read FilePath.doc if you have

questions on file path. Copy SecretMessage.java into your NetBeans or other IDE

tools.

2. Finish the main method that will read the file secret.txt, separate it into word

tokens.You should process the tokens by taking the first letter of every fifth word,

starting with the first word in the file. These letters should converted to capitals, then

be appended to StringBuffer object to form a word which will be printed to the

console to display the secret message.

secretmessage.java

import java.io.*;

import java.util.StringTokenizer;

public class SecretMessage

{

public static void main (String [] args)throws IOException

{

FileReader file = new FileReader ("secret.txt");

BufferedReader input = new BufferedReader (file);

StringTokenizer tokenizer;

String fileContents;

String wordToken;

int count = 0;

char letter;

StringBuffer strbuff = new StringBuffer();

// To do - Task #2 step 2

// read one line of the file into fileContents

tokenizer = new StringTokenizer (fileContents);

while (tokenizer.hasMoreTokens())

{

// To do - Task #2 step 2

// get nextToken of tokenizer and assign it to workToken

wordToken = tokenizer.nextToken();

if (count%5 ==0)

{

// To do - Task #2 step 2

// get first letter of the wordToken

// Change it to upper case

// appent it to strbuff

}

count++;

}

System.out.println(strbuff);

}

}

Answer 1

The scret answer is JAVA, here is the code:

import java.io.*;

import java.util.StringTokenizer;

public class SecretMessage

{

public static void main(String[] args) throws IOException

{

FileReader file = new FileReader("secret.txt");

BufferedReader input = new BufferedReader(file);

StringTokenizer tokenizer;

String fileContents;

String wordToken;

int count = 0;

char letter;

StringBuffer strbuff = new StringBuffer();

// To do - Task #2 step 2

// read one line of the file into fileContents

fileContents = input.readLine();

while (fileContents != null)

{

tokenizer = new StringTokenizer(fileContents);

while (tokenizer.hasMoreTokens())

{

// To do - Task #2 step 2

// get nextToken of tokenizer and assign it to workToken

wordToken = tokenizer.nextToken();

if (count % 5 == 0)

{

// To do - Task #2 step 2

// get first letter of the wordToken

// Change it to upper case

// appent it to strbuff

char first = Character.toUpperCase(wordToken.charAt(0));

strbuff.append(first);

}

count++;

}

fileContents = input.readLine();

}

  

System.out.println(strbuff);

}

}

if (count % 5 == 0) {

// To do - Task #2 step 2

strbuff.append(Character.toUpperCase(letter));

}

count++;

}

}

System.out.println(strbuff);

}
