Create A New Line On TXT File Between 2 Lines

Feb 6, 2015

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.

Read Lines With Specific Characteristics From A File / Exclude All Others Line?

Jan 16, 2014

I am trying to write method to read lines with some specification from a file. for Example,

my text file contains following:--

12-01-0113:26San Jose12.99DVD
12-12-3009:40Miami13.50Music
14-08-3010:20Arizona16.03Scientist
11-07-1009:10New York25.00ColdPlay
14-08-3010:20Arizona18.04MeetYou
14-08-3010:20Arizona50.03Scientist
11-07-1009:30New York25.00ColdPlay
11-07-1009:20New York25.00ColdPlay

tab separated values, for different columns and these are the lines only I want method to read.Now suppose if any is there as below, or even enter

12-01-0113:26San Jose12.99DVD
12-12-3009:40Miami13.50Music
14-08-3010:20Arizona16.03Scientist
11-07-1009:10New York25.00ColdPlay
14-08-3010:20Arizona18.04MeetYou
[new lines]
14-08-3010:20Arizona50.03Scientist
11-07-1009:30New York25.00ColdPlay
//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"));

Application That Reads In A Line Length Followed By Individual Lines Containing Text

Jan 9, 2015

I'm currently learning Java and have been set an assignment that requires me to do the following:

Write an application that reads in a line length followed by individual lines containing text. No input line will be longer than the read in line length. In the text lines each word will be separated by a single space. The lines of text to be reformatted and then output so that the output lines of text have straight left and right margins. The last printing character in each line will be at character position (line length). In the text output the character '.' is to be used to represent the space character.

Page 2 - Gyazo - 470cf689a3126b7ab6c64bb14ae80a0d.png

I'm trying to take this task on, but I'm unsure as to what exactly I'm supposed to do with part of it. For one of the methods I need to "work out how many extra spaces will need to be added to make the line width characters long.", how would I go about doing this?

How To Make File Reader Object Move To Next Line If There Is No More Input On Line

Feb 18, 2015

How do I make the file reader object move to the next line if there is no more input on the line. Here is my text and output file as you can see that my text file column cuts off on the 2nd line after 70. I want to read that next line which is 100 into my labs variable however its reading it into my final exams variable. I'll also post the code but I didn't think it was necessary.

textfile:
100908095
1008070
10070

output:
Labs Projects Tests Final Exams
100908095
1008070100
70

[import java.util.Scanner;
import java.io.*;
public class MyGrades
{
public static void main (String[] args) throws IOException
{
int lab, project, test;
int finalExam;//Par and Player values

[Code]...

not sure if I code wrapped it correctly

I/O / Streams :: Reading A File Line By Line And Deleting It

Oct 15, 2014

If I want to read my file line by line and when it hits a certain value from that point it should start deleting the lines until the tag ends.Just curious will my code actually work at the moment or not because it goes through so many times then goes straight back to the variable declarations at the start of the method and never hits the console print line.

public void removeEnvironment(){
//declare variable to environment id
String environmentID = "Environment id";
String lines = null;
boolean lineFound = false;
boolean end = false;

Appending New Lines In A File

Jan 21, 2015

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.

Reading Pairs Of Lines From A File?

Jul 19, 2014

This what the data file looks like -

5165168416516988798484984984984984

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) {

Reading A File And Splitting Certain Lines Into Arrays

Jan 30, 2015

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?

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?

Pickup Selected Text File And Read Line By Line And Output Text Into Visual Text Pane

Dec 12, 2014

I am checking how to do following task.

01. pickup the selected text file and read the line by line and output the text in to visual text pane.

what i did:.

01. I wrote code that read the text file and output in to jave console/ also some of the interface.

the code read txt file:

Java Code:

String fileName = "C:/Users/lakshan/Desktop/lawyer.txt";
File textFile = new File(fileName);
Scanner in = new Scanner (textFile);
while(in.hasNextLine()){

[code]....

so it will read any text file dynamically and output to the text pane in interface. I think scanner code must be execute after the select the file from the browser and set the scanned result in to variable. then later out put the var as string in some jswing component?

Not Reading All Lines While Comparing User Entered Name To The One That Exists In File?

Jan 21, 2014

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

Split Text File Lines Into Pieces And Put Them In Different Array Lists?

Mar 14, 2015

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).

How To Make A Text File Only Use Lines In A Text File Beginning With A Certain Letter

Mar 15, 2015

I have a program that reads lines of text, but some of the lines of text aren't applicable and break the program. I'd like to put a letter in front of the lines in the .txt file I want to use, such as a #.

I need to make an if loop that'll check for the first letter on the line being #, and use the line in the program if true and skip if false. I'm guessing a boolean variable would be useful here to be true or false depending on the presence of #, but I don't know how to only read the first letter of each line, how can I do this?

Read File And Input Each Line Of File Into Array

Mar 21, 2015

I am trying to read a file and input each line of the file into an array. I have not set the array size as I was hoping to fill the array using a while loop. Unfortunately the scope of the array does to work inside the while loop so I am being told that the array 'students' has not been initialised even though it has just outside of the while loop. Is it possible to do what I am trying to without having the array initialised in the while loop as surely the array will be reset every time if it was in the while loop? Here is my code:

public static void students(String file) throws FileNotFoundException {
try {
File studentInfo = new File(file);
Scanner input = new Scanner(studentInfo);
