Code To Open Up TXT File And Display Only First Five Lines?
Apr 7, 2013
I am trying to write a java code for a homework problem in my intro java class but im having problems. This is the problem:
Write a program that open the MyFile.txt and read from a file with these criteria.
1)-The program should display the first five lines of the file’s contents only.
2)-If the file contains less than five lines, it should display the file’s entire content. You must check for end of file and less than 6 lines on the loop iterations.
3)- your program should use loop to read the line by line of the file MyFile.txt.
The serperate myfile.txt has this
I can still remember, at the end of that year, we sat for the last time in our circle together. She played us her favorite song, "like a bridge over troubled water" and quietly passed out a gift she had made for each of us.She had made each of us a pottery heart with our name and the date on it on the back each read "I believe in ME".We all cried including her. She told us she would always remember US. We believed she would.
and this is what the code is suppose to look like after you run it : Java33.png
And this is what i have so far : Java22.png
what needs to go next to complete the javascript to show the first 5 lines of the text files?

If you were given a problem to search for an error in a section of code but it is incredibly long, what are some ways you can go through the lines of code quickly?

Using JOptionPane, I want to display in one window:
1: ***
2: *****
etc
where 1 is the element of the array, and the * are a percentage calculated in a loop. My variables are all being input fine, but the output is 100+ windows:
1:
*
*
*
2:
*
The CLI way would be with print() and println(), but I'm having a tough getting it to be visual.

I am just displaying my values in different ways and I can't seem to get my values to display one at time on new lines. I dont know why that isn't compiling. The part i am having trouble with has the "Not Working" tag in the code.
[highlight=Java]
//Trying to figure out how to use /n
public class Test
{
public static void main(String[] args)
{
int gold= 5;
int silver= 3;
int bronze= 1;

I have looked over other people code relating to files that are related to my actual studies in class. My teacher hasn't worked on a lot of file problems so I want to gain some understanding on it.
1.) I have this class with variables declared
import java.io.*;
public class FileDisplay {
private String filename;
FileWriter outputfile;
File Inputfile;
I'm aware that having a private variable would not allow that variable to be accessed outside the code. Vice versa, public variable would do that. The FileWriter and the File Inputfile is something I don't understand, especially have them in classes. What is the purpose of them?
2.)
public class FileDisplay {
private String filename;
FileWriter outputfile;
File Inputfile;
[Code] ....
I have made this code here that opens the output and input file. If I make another method, how would I display the text onto that same file. Hard to clarify for me, but in each method do I just keep creating :
FileWriter outputfile=new Filewriter(filename)

I am trying to make a java code that reads in lines of text and returns the number of spaces in each line.I think i have made it but i can not compile it..
Here is my code:
class Mainh {
public static void main( String args[] ) {
System.out.print( "#Enter text : " );
String text = BIO.getString();
while ( ! text.equals( "END" ) )

I have this part of the file.
class CreateFile implements ActionListener{ // MailOrderCreateFile.java
@Override
public void actionPerformed(ActionEvent ae){
String getDestination = txtDestination.getText();
file = new File(getDestination); // needed for Creating and Displaying the file
currentTime = txtCurrentTime.getText();
try {
FileWriter fw = new FileWriter(file);
[Code]...
What I wanted to do is that every time I press the button that will activate this part of the code, it will write to a .txt file defined in my txtDestination var (a JTextField). After the first time the file was created, it must append a new line every succeeding presses. However, everytime I do this, it just simply overwrites the contents of the .txt file. The example output would have been like this:
First time.
O R D E R D E T A I L S:
Time ordered: 01/21/2015 Wed 10:21:54 PM
Item number: 10
Item price: $4.59
Quantity ordered: 12,321
Total: $56,553.39
[Code]...
I've tried createDetails.write but to no avail.

This what the data file looks like -
5165168416516988798484984984984984
9898798798798
1556516846516518498
51688484979789798798798491
The problem was to make code which will combine consecutive lines which contain some data into one line and print it. I made a solution that works.
import java.io.File;
import java.io.FileNotFoundException;
import java.util.NoSuchElementException;
import java.util.Scanner;
public class Filez {
public static void main(String[] args) {
File file = null;
[code]...

<globalVariable>
<name>CERTIFICATE_PASSWORD</name>
<value>fgfdgfgf</value>

Lets say this txt file contains 2 lines.
---------
hello
bye
---------
What would i have to do to insert a a piece of text in between hello and bye? I would like for the it to search for "hello", then add a line after it so it would look like :
-------
hello
newtext
bye
-------
I have these 2 methods that work as intended, but i just cannot seem to do what i've stated above.
Java Code: /**
* @param location
* Location of the .txt file.
* @param text
* The String to search for in the .txt file.

i have an older file I was working on 2 months ago and when i try to open it in eclipse I get a message corruption error. I know this is not possible since I was just working on it a while back, and it's the same program version as what i am currently using..Or would I do a file import instead?

Is there a way we can open a .chm file stored at server through jsp application without downloading the file and saving it to the local machine.
What I googled is : we cannot download .chm files from a web browser and simply click Open. Download the .chm file to your computer first, right-mouse click it in Windows Explorer and select Properties. Then click Unblock.
But I want my users to simply view the file without downloading it.

Me and my mate are struggling to get our code to split a line in a text file which are separated by (":") and store into an array. We've managed to split each individual line into an array, but cannot work out how to do it with multiple splits over one line.
try{
FileReader fr = new FileReader("C:UsersTomDocumentsNetBeansPro jectsfootballA2_Tom_Tyler2srcukackingsto nci5100football_a2 om_mcLean_tyler_wattsmo delfootball_teams_phase1a.txt");
BufferedReader br = new BufferedReader(fr);
while(br.ready()){
String nextLine = br.readLine();
String[] fTArray = nextLine.split(",");
System.out.println();
for(String str : fTArray) {
System.out.println(str);
}
}
This code works but how would we do it for multiple splits over one line, along with this array?

I was just wondering how would I create a jar file that would open 3 other jar files when I open the jar file with my batch file it and when I type stop in the batch file it will out put the stop command into all 3 of the other jar files.
This is for my Minecraft server so I can launch them all at the same time and inStead of having to enter the commands in all the server batch files I just have to do the command in 1 I know their is things like multi craft to do this but I want the code so I don't have to use multicraft.

I have recently taken up some java after a period of time learning batch scripting. the issue I have run into is that my build compiled and ran just
fine when invoking from within the netbeans IDE but after that I 'cleaned and built' the jar and the IDE stored it in the directory that I specified while installing.
I went to that folder, double clicked on my gui and go nothing. So then I opened a command prompt did, "java -jar myapp.jar" and got the following of which has me completely lost:

Logic her eis when user selects option1, it asks for user to enter name and as soon as user enters name, it should compar name to existing names in txt file. I have user while loop and for loop but for some reason, it doesnt compare properly as there seems to be some mistake in looping and it just read first line or you can say single line rather than comparing it with all lines in txt file. i have attached votes.txt file with this. Also, if user doesnt exists infile, it will ask user to enter vote as yes or no and add it to file and then count total number of Yes and No votes from file and compare them.
my votes.txt file looks as below with two columns namely (name and vote).
Hiren No
samir yes
bob no
rikul no
master yes
patrick no
summer yes
bhanja no

For example, if I had a text file with one line such as "first, second, third", would there be a way to make it so I could make "first" go to the first array list, "second" to the second, and "third" to the third?
I haven't posted any of my code so far as it wouldn't be right to be handed the finished code on a platter and I should put the work into it, but I'd just need a loop to make it go through the rest of the lines in the text file to add all the first, second and third parts of each line, right?
(I already know how to input data from a file, but not how to split up a line into bits to put into different array lists).

//This line should not be read
even this should not be read #$%^&
11-07-1009:20New York25.00ColdPlay
That particular line should be escaped. Till now I have done when the file format is proper, and it is as below:--
public static void main(String[] args) {
BufferedReader br = null;
String temp = null;
List<String> arrayRead = new ArrayList<String>();
try{
br = new BufferedReader(new FileReader("D: estingSalesData.txt"));
