Why is it simple for a word processing software (one that reads number of words, words greater that x characters etc) to deal with text file(.txt) and not with a doc file (.doc) file?? Is there any special requirements or what are the points taken into consideration while developing the software for a .doc file?
View RepliesThe intentions of this program is to prompt a user to enter a file name, and then reads the file. The program will prompt the user to enter a word that needs to be corrected. So lets say I have a text file containing "My name is OP and I Like goind to the Park!" I want to change "goind" to "going",
Now, my second method "isSimilar" executes a similar word with more than one same letter and same length, but I dont know how to execute that whole thing in my third method "correctThisLine" . How I can call that isSimilar method and read in that text file and change that word into that?

It seems we have abandoned Dice/Die(s), and are now working on something completely foreign. I don't even have a code to start with because I haven't the faintest clue what is going on here (no notes given on this topic, as usual). We are given 4 half-written programs to work with.
The instructions are:
"Examine the FormLetterEntry abstract class, and create the two derived classesTextEntry and DataItemEntry. Be sure to implement all the abstract methods in each derived class."
This is the code we were given:
package homework5;
import java.util.Properties;
/**
* Abstract class representing the entries in a form letter.
**/
public abstract class FormLetterEntry {
/**
* Retrieve the template string for this entry
* @return the value of this entry in a template
**/
[code].....
I understand (and correct me if I am wrong) that a derived class is a class that is created from a base class via inheritance. What I don't see are any notes on how to write a derived class. I see some notes online on how to do so, but they don't fit with what he's written above. What he means by "Be sure to implement all the abstract methods in each derived class."

I am trying to do is extract numbers that are in word format in a long String, i.e. a song, and return each of their numerical values, in order to add them all up. So I'd like to calculate the sum of all of the numbers in the text. This has to work for any piece of text and for all numbers up to a trillion.
So I broke the string down into tokens and stored them in a String []. And I divided up the possible numbers in word format into:
LARGEST: thousand, million, billion, trillion
HUNDRED: hundred
TENS: twenty, thirty, forty, fifty, sixty, seventy, eighty, ninety
UNITS: one, two, three, four, five, six, seven, eight, nine
SPECIALS: ten, eleven, twelve, thirteen, fourteen, fifteen, sixteen, seventeen, eighteen, nineteen
I believe that these are the only words that it will need to recognize. I began reading the tokenized string from right to left and then when I came across a unit, special or tens as the first number I hit, I would then set it's numerical value and check if the word before was also a number and whether to add or multiply etc. i.e. First number hit is a two, if the number before is sixty, then I would just add it to sixty and check the word before that and so on.
However, when implementing it, it seems like an extremely long way around it. How I could implement this in a swifter manner? An example of it working would be:
"Nine Million rockets turned Three times and met Twenty Two Aliens", it would extract, Twenty Two as 2, then 20 = 22, then extract Three as 3, and then Nine Million as 1,000,000 x 9 = 9,000,000
9,000,000 + 22 + 3 = 9,000,025
Consider in a Document if a String " Hello" is Encoded and stored as "XYZAB"
I want to search the text on document for a word "Hello" and Replace the word with "HelloWorld"
The Program will encrypt the word "Hello" and Search the file then return the encrypted code as "XYZAB" Found
Now i have to replace the word "Hello" with "HelloWorld" in encrypted form so that the Letter "XYZABEFGHI" is replace in the place of Hello where "World" is encoded as "EFGHI"
Now the Problem is If there is more number of occurrence of the word "Helloworld" exist in the file... How can i Replace only one particular occurrence What can be done to select the particular occurrence.

cards[c] = new BingoCard(sc.nextLine); mh_sh_highlight_all('java');

How can I do so? Because I can output the number 1 from both text files even though I specify the name.
I'm refitting a snippet of code I found on the net to write stuff into text files. After a bit of fiddling, here's what the code looks like in one of my classes:
public void addItem(String Item){
try{
Writer out = new OutputStreamWriter(fos, "UTF8");
out.append(Item);
out.flush();
// out.close();
}
catch (IOException e) {
System.out.println(e.toString());
}
}
The original snippet included the close() method. However, when I tried to do a test run writing multiple lines, I'd get an IOException about the stream being closed. I removed the close() method line, everything seems to work the way I want it, but I just wanna know if there's anything I'm missing out on by not having the close() method anywhere, especially when the IDE finds it important enough that it lit a warning about the stream not being closed somewhere as I was repurposing the original snippet.

I've been trying to write a program for some time now, but im encountering problems while trying to complete it. The program has a student class and a course class (set up with some info about the class, like #, professor name, course title, course time). Now, i have a text file in the workspace, and i have to import the data from the textfile, and thats just what i did, but then there is an option which allows the user to delete a course only by inputing the course number, and when he does that, the program outputs the course's name, and confirms the deletion of the course (From the student's record, i created a vector for that and imported all the courses from the text file). But how can i let the program know what's the name of the course when the user inputs the course number ???
When the data is read from the file, objects should be created and added to the student's course record. <- i think here's where i messed up ? i imported the data, but how can i actually make them objects before adding them into the vector ?

I am trying to split the contents of the text file and assign the value on the left of the separator to a variable and the value on the right of the | separator to another variable.

Crazed Boy|20
Hello|5
MSB|6.5
public class Main {
public static void main(String[] args) {
try {
BufferedReader infile = new BufferedReader(new FileReader("test1.txt"));
for (int i =0; i < 3 ;i++) {
String s = infile.readLine();
String[] ss = s.split("|");

I keep getting IOException in my sample code, why is this so ? I assumed the split() method is supposed to output for the 1st iteration:
ss[0] = Crazed Boy
