How To Make A Text File Only Use Lines In A Text File Beginning With A Certain Letter
Mar 15, 2015I 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?
Pickup Selected Text File And Read Line By Line And Output Text Into Visual Text Pane
Dec 12, 2014I 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?

Converting CSV File To Array
Jun 4, 2014There is a csv file that contain 10 rows and two columns. I want to convert this csv file to array. Each cell contains several line of string. But the output is wrong. After printing output, each cell of array contains a line of one cell of csv file.
for example csv file contain
book, this book is good. that book is good.
cook, cooking is enjoyable.
After printing output of array:
book,this one is good
that book is good, null
what is wrong with this code?
Code is :
public static void main(String[] args) throws Exception {
Scanner main = new Scanner(new File("C:UsersaDesktopook1.csv"));
int line=0;
String [][] temp1=new String [10][2];
while (main.hasNext()) {
temp1[line]=main.nextLine().split(",");
line++;

Converting Char To Integer From File
Feb 28, 2014I want to make a program that reads numbers from a text file and transforms them into integers and then displays on the screen, but i can not do this with numbers greater than ten as the read () method of the BufferedReader only reads character by character. If he has to read the number 34 or 2343, for example, i don't know how to turn that chars into a single integer value. How can i do this in a more elegant way than the way i show to you below? That was the solution i found, but i believe there is a cleaner and more elegant way of doing. I would also use the Integer and Character type to solve this problem. I'm trying to use less primitive data types. The following code works fine just with number 0 -> 99.
I would like to use Character and Integer now.
int number[] = new int[2];
int i, carac;
i = 0;
do {
carac = leitor.read();
if (carac != -1 && carac >= 48 && carac <= 57) {

Read Text File Into Object Array And Creating Random Access File
Dec 8, 2014I am working on a project that requires me to build a database with random access file, representing products, the base product contains a name (about 30 characters), a price (double), and a quantity (integer). I have worked on this project for probably 15+ hours and have tried so many things and feel like I've barley made any progress...
The part i am really struggling with is taking the data from the text file and creating an object array with it using the product class. Once ive accomplished that, i have to use that data to create a random access file with the data.
Here is the base Product class that must be used to create the objects for the array.
public class Product
{
public String pName;
public String stringName;
public double price;
public int quanity;
[Code] .....
And then here is the data from the text file that i must extract to use to create product objects.
Dill Seed,938,34
Mustard Seed,100,64
Coriander Powder,924,18
Turmeric,836,80
Cinnamon (Ground Korintje),951,10
Cinnamon (Ground) Xtra Hi Oil (2x),614,31
Cinnamon (Ground) High Oil (1X),682,19
These continue for about 40-50 entries, they are not separated by a blank line though i had to add those so it would display correctly, each entry is on its own line with name separated with spaces, then price after a comma, then quantity after the second comma.....

Read Text File Into Array Ask User To Save File And Print Data
Jul 14, 2014New to programming. Am supposed to create a program that reads a text file (of integers) and computes a series of computations on these integers. I don't have the code for the integers in my code yet, (i know how to do those), but am struggling getting the array to simply print in the print writer. I have the user select a text file, read the file with a scanner, and then save the computations done from my code into another file. specifically, the problem is as follows: Write a program that uses a file chooser dialog to select a file containing some integers. The file contains an integer N followed by N integers. The program then uses a file chooser dialog to let the user specify the name and location of an output file to write results to.The data written to the output file will be as follows
(1) The original list of N numbers from the input file,
(2) The original list of N numbers printed in reverse order of how they appear
in the input file.
(3) The sum and average of these numbers,
(4) The minimum of all the numbers,
(5) The maximum of all the numbers.

How would I then read from this text file and then create those files using 'new File()'?
Here is my code:
