Viewing Java File As TXT File

Jan 25, 2015

I have a java assignment concerning formatting. I know I have no syntax errors but that doesn't mean that my formatting is correct and I can't figure out how to create a .txt file and view my code in notepad just to verify the formatting.

public class Assignment1b {
public static void main (String[] args) {
String[] header = {"Wilson", "Office", "Supply", "Inventory", "Listing"};
String[] columnhead = {"Number", "Description", "Price", "Qty", "Net Price"};
String[] line1 = {"AB35", "Swingline Stapler", "19.95", "125", "2493.75"};
String[] line2 = {"CP05", "Canon Copier", "329.65", "175", "57,688.75"};

Viewing Website File Tree

Apr 25, 2014

This is probably more of a web-based question. I have a basic web crawler I wrote with Java (using JSoup) which crawls through our repositories and stuff to locate the paths to certain snapshots and whatnot. It crawls through using the file tree which gets exposed when you try to go to a directory in a URL.

The problem I am having is that some of the directories contain index files, which means the connection to the directory redirects from the file tree to the index file. Any way to prevent that redirection?

JSP :: Viewing / Inserting And Updating Records In Same Page

Dec 10, 2014

I need to view, update and insert records through a jsp page.example: Employee details..If we give an admission number of an employee, and if the admission number exists in the database then the details like Name, DOB, DOR, Address, Contact info should be displayed in the appropriate fields.(simply a select query in SQL) . The fields are editable and if we need to make any changes we can update in that details itself. If admission number doesn't exists means we can insert all the details except the admission number and a temporary admission number is generated and displayed. The problem with this is i can't able to revert it to the same page.

I know this sounds stupid and you may want to say why cant we directly copy the file, I am doing a proof of concept and using this as a basis.

Read Text File Into Object Array And Creating Random Access File

Dec 8, 2014

I 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, 2014

New 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.File;
import java.io.IOException;
import java.io.PrintWriter;
import java.io.Writer;

Servlets :: File Is Located In Root Directory Of Project But System Cannot Find File Specified

(The system cannot find the file specified)

My file is located in the root directory of the project.

And here is how I indicate the path to it:

String filePath = "default.jpg";
InputStream inputStream = new FileInputStream(new File(filePath));

If I put the file in the Eclipse folder, it works... But I need it to work if I put it in my project's root folder.

Read Input File And Create Output With Anagram For Words In File

Sep 24, 2014

Well my code is supposed to ask for an input file and then (ex: input.txt), read the input file and create an output.txt file with the anagram for the words in the file. Also it should be displayed on the screen. However my code doesn't display the anagram on screen or the output file!

Heres is the code:

import java.io.*;
import java.lang.*;
import java.util.*;

/* This program will read a file given by the user, read the words within the file and determine anagrams of the given words. If the file that the user inputs is empty, then the program will output "The input file is empty."
* The program will read the file line by line, counting the total number of words read. If there are more than 50 words, "There are more than 50 words."
* will be printed, and the program will terminate. After each line is read, the words in the line will be separated,punctuation characters will be removed, and upper case characters will be switched to lower case.
* If any word is larger than 12 characters, that word will not be considered in the total amount of words in the file and it will not be sorted.
* After each word is read, the letters will be sorted and stored into an array containing each
* word's 'signature'. After all the words have been read, words will be printed to the output file on the same line based upon their signature.
*/

public class Anagram {
//Creating constants for maximum words in file and maximum chars in word
public static final int MAX_CHARS = 12;
public static final int MAX_WORDS = 50;

Checking If File Exist - If Returned True Then Check Said File For ID

Sep 25, 2014

If I'm checking using an if statement if a file exists like so:

public boolean export(String envName,String fromFile,String toFile) {
Vector<String> vector = new Vector<String>();
File file = new File(fromFile);
if(file.exists() && file !=null) {
return true;
}
return false;

If it returns true for existing then how would I do another if statement that would say if file returned true then check said file for an id. If Id exists extract all data associated with that id and store in Vector object. Would it be like this:

if(file==true)
{
//enter rest of code
}

PrintWriter Creates File But Doesn't Print File

Nov 7, 2014

This is a college course assignment that consists of classes TotalSales and TotalSalesTest.In the main program I have created a two dimensional array to output a columnar layout with cross-totals in 4 rows and 5 columns. This program outputs sales totals by row for each sales person(1 - 4) and output by column for products(1 - 5). I have created extra elements in the array to store total for rows and columns. So far both classes compiles. The problem is that although the PrintWriter creates a notepad file, it doesn't print to it. I don't seem to understand the input and output methods completely. I finished another program similar to this using basically the same try and catch that read the file and printed out a document in notepad. Here is the code and I'll try include the input file.

import java.util.Scanner;
import java.io.*;
public class TotalSales {
private int salesPerson; //declare class variable

Accessing One Class File From A Fragment Or A MainActivity File

Dec 4, 2014

I have several different PopupWindows that i want to access from the same fragment. I would like for each PopupWindow to be it's own java file. Here is trimmed down code from an example showPopup.java file,

showPopup.java
public class showPopup {
//public class showPopup extends Activity implements View.OnClickListener{
//public class showPopup extends Window {
public static Context appContext;
PopupWindow popupWindow;
SQLiteDatabase db;
EditText edSpeciesLookup,edSpeciesLookupRowid;

[code]...

How do I configure inheritance to allow showPopup() class to reside in it's own Java file and be called from another class (file)? I've reviewed several hours of online resources as well as my reference books with no productive illumination. I've tried a number of possible implementations and extensions such as "public class showPopup extends Activity implements View.OnClickListener{...", and "public class showPopup extends Window.
