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?

Copying Excel File Using Jxl API
Jun 10, 2014Java Code: import jxl.read.biff.BiffException;
import java.io.*;
import java.util.*;
import jxl.*;
import jxl.write.*;
public class MainProgram{
public static void main(String[]args){
try{
Workbook workbook = Workbook.getWorkbook(new File("myfile.xls"));
[Code]...
Not sure why this code isnt working for me, it makes an empty excel file called output, but never copies the contents in "myfile" to that output file. I have Excel 2010 but I saved both of them as 97-2003 workbooks. Am I missing something? Do you have to go cell by cell to copy an excel file with JXL?
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.

import java.io.IOException;

Jun 25, 2014Let's say I have a text file and in the text file exists file directories as such:
'assets/picture1.png'

And so on...
How would I then read from this text file and then create those files using 'new File()'?
Here is my code:
private void getFiles() throws IOException{
files = new File[10];
Scanner scan = new Scanner(new File("files.dat"));
int count = -1;

It does print out those files, but it doesn't create them.

Apache Poi To Create Excel File From JTable
Sep 17, 2014I'm using Apache Poi to create an Excel file from a JTable.
I want to open the file directly in Excel, rather than first write it to disk and then open it from the disk.
FileOutputStream output = new FileOutputStream( StolleExcel.xls" );
workBook.write( output );
Desktop dt = Desktop.getDesktop();
dt.open( new File( "StolleExcel.xls" ) );
output.close();
Is there a temporary way of saving the Excel object then just opening it with Excel, so the user can save or edit whatever they want?
