Store Data From A File Into Array Of Type Product?

Mar 17, 2015

public class InputFileData {
/**
* @param inputFile a file giving the data for an electronic
* equipment supplier’s product range
* @return an array of product details
* @throws IOException
*/
public static Product [] readProductDataFile(File inputFile)
throws IOException{
// YOUR CODE HERE
}

This code is meant to be used to read a text file and store the data in an array of type Product[]. I know how to read in a text file and have it sort it into an array, but I've never seen code laid out in this fashion before (specifically "public static Product[]", and I'm unsure how to work with "(File inputfile)". I've looked all over the place but can't find any examples of anything like this.

Also, the code given cannot be changed, as it's that code I have to work with.

I still don't understand how to use it as a whole. For example, do I read the file in the main and have this method read that in and output to the Product class? Do I read the file in this method? I can't work out how to make this work when I have to use this method.

Get Data From Config File And Store In Array Without Using Split Method

May 8, 2014

How i can get the data from a file, for a key that have multiple values without using split method and i want to store that data in an array

file name:"new.txt"[contains below data]
Name=google.com, yahoo.com,facebook.com
Attachment=abc1,abc2,abc3

I am successfully able to do this using following code

Properties props = new Properties();
String configFilePath = (Cjava_confignew.txt);
props.load(new FileReader(configFilePath));
String TestName = props.getProperty(Name);
String test[] = TestName.split(,);

Now i just want to store the values for key "Name" in array without using TestName.split(,); but i am not able to do this.

I have also used .yml file to avoid this but did not succeed, some way to do this

file name test.yml

Name
-google.com
-yahoo.com
-facebook.com

Attachment
-abc1
-abc2
-abc3

i want to store multiple values for single key(Name) within the array

Fetch Type Of Product From Scale

Sep 11, 2014

Below is current process :

We have an application running successfully where we fetch the weight of product currently on Production Line using Java.

All the products on line belong to same order and are of same type.
User at beginning enter the type of product and starts the production line.
 
Proposed new process: Now client want that multiple type of product can belong to same production order. i.e. on a production line different type of products can come one after other. So we should now fetch the type of product also.
 
The Question : what are different possibilities in which we can find the type of product. Can java fetch color of a box ? If we use scanner on line that scans the product and sends the color information to Java.

Above is just a possibility. Can there be any other parameters that Java can use to differentiate in type of product ?
 
Currently we are clueless. What ever are the possibilities in Java we can propose the same to client. Even if that requires additional hardware.

Open A File And Store Contents Into A Two Dimensional Array

Feb 11, 2014

So I am trying to open a file and store the contents into a two dimensional array. I seem to have no problem using this same basic code to read the file and output it. But when I try to change it so that all the data is stored into the array, it does not work.

Java Code:

public void convertFile()
{
String filePath = ("C:UsersBradDownloadsFB1.csv");
String [][] rowCol = new String [429][6];
try
{
BufferedReader br = new BufferedReader(new FileReader(filePath));

Code Storing Input Data In All Three Of Product Objects?

May 7, 2014

My problem is that in my program, I have the user input data for one of three product objects, however when I read the data for all three objects, the same data is stored in all of them.

Anyway this is the method from the Interface class:

private void readInput() // the only method in the program that accepts product data from the user {
Store matesStore = new Store();
String name;
int demandRate, productChoice;
double setupCost, unitCost, inventoryCost, sellingPrice;
Scanner console = new Scanner(System.in);

[Code] ....

And here is the method from the Store class:

public static void addData(int option, String newName, int newDemand, double newSetup, double newUnit, double newInventory, double newPrice)
//sets the product data for a particular product {
if (option==1) setData(product1, newName, newDemand, newSetup, newUnit, newInventory, newPrice);
else if (option==2) setData(product2, newName, newDemand, newSetup, newUnit, newInventory, newPrice);
else /*(option==3)*/ setData(product3, newName, newDemand, newSetup, newUnit, newInventory, newPrice);

[Code] ....

The problem I had was with static variables and methods.

Read Characters From Txt File / Store Them Into 2D Array And Print Information

Oct 10, 2014

The point of this program is to read characters from a txt file and store them into a 2D array. After this has been accomplished, the information is to be printed in the same manner it is read from in the txt file.

Here is the code I have so far:

import java.io.File;
import java.io.FileNotFoundException;
import java.util.Scanner;
public class Main
{
public static void main(String[] args) throws FileNotFoundException

[Code] ....

And this is the error I am receiving when trying to accomplish the goal of the project:

Exception in thread "main" java.lang.NumberFormatException: For input string: "############"
at java.lang.NumberFormatException.forInputString(Unk nown Source)
at java.lang.Integer.parseInt(Unknown Source)
at java.lang.Integer.parseInt(Unknown Source)
at Maze.<init>(Maze.java:15)
at Main.main(Main.java:20)

What's going on here and how I can correct this?? The information I am trying to store in a 2D array and then print is this:

############
#.#........#
#.#.######.#
#.#....#...#
#.###.*#.#.#
#...####.#.#
#.#.#..#.#.#

Program Should Read File Contents And Store Information In Array Of Golfers

Dec 3, 2014

The main method will drive your program by doing the following:

-Create an array to hold all the individual golfers and par scores (type is Golfer[ ]).
-Prompt the user for a data file containing the Par scores and the player names and score. The format of the input file should look like

Par, 3, 4, 4, 3, 4, 3, 5, 3, 4
George, 3, 3, 4, 3, 4, 2, 3, 3, 4
Paul, 4, 5, 4, 3, 6, 3, 4, 3, 5
Ringo, 3, 3, 4, 3, 4, 2, 4, 3, 4
John, 4, 4, 4, 3, 4, 2, 5, 3, 4

Your program should read the file contents and store the information in your array of Golfers.

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;

Generate 10 Random Integers / Store In Array And Then Calling A Method To Display Array

Nov 8, 2014

So I need to generate 10 random integers in the range 1-20 but i have to store them in an array called numbers. Then I have to call a method called displayArray which displays the contents of the array and for the assignment i have to use a for loop to traverse the array. The method header for the displayArray method is:

public static void displayArray(int[] array)

This is what I have done
 
public class RandomIntegers {
 static int numbers = 0;
public static void displayArray(int[] array) {
System.out.println(numbers + "Numbers Generated");

How To Store ResultSet To Other Data Structures

Oct 28, 2014

I have a java query like this

query ="Select major_career.Major_Title, career.ISCOTitle,career.FS.... " //only partial,
// I swear the query is correct
resultSet = statement.executeQuery(query); //this executes it
relArr = new ArrayList<String>(); //don't worry it is intialized

In the code below I tried to store the resultset components into the arraylist

int j = 1;
while (resultSet.next()) {
while(j<=numberOfColumns){
relArr.add(resultSet.getObject(j).toString());
j++;
}
} // end while

I am not sure whether the arraylist is able to store the result set because when i try to display it like show below it only shows some rows and only the first column

Iterator it = relArr.iterator();
while (it.hasNext())
{
System.out.println(it.next());

I want to manipulate the resultset results in my program by copying the resultset values to other datastructures.

Store Data By Their Ascending IDs Using Java

May 8, 2013

I am making a program to read data from excel files and store them in tables by their IDs. I have managed to read all the data from excel files as a string and store them in a table. But my project is to store them in table by ascending IDs. I have created the comparator in another class but when i call it in the main class nothing happened. The data that I have to store is like the below:

ID     Name     Salary     
50     christine     2349000     
43     paulina     1245874     
54     laura     4587894     
23     efi      3456457     
43     jim      4512878     

The codes are below:

import java.io.File;
import java.io.FileInputStream;
import java.io.IOException;
import java.util.ArrayList;

How To Read Data From Text File And Place Into Array

Nov 15, 2014

I'm trying to figure out the necessary code for reading integers from a text file, then placing them withing the two-dimensional array I have created, and then finally printing the array using a nested for-loop. I have attached the file I would like to read from. I'm having trouble figuring out how to reference the text file with the integers, and also how to properly create a dynamic preface for each row of the array. I want the preface to display as "Week #: ", with # being the row number. I tried to create an integer to be used that way, but NetBeans tells me whatever integer I declare has already been defined in method main. I know I need to use scanner to read the file. I would like the output to display like this:

Quote
Temperature Data

Week 1: 73 71 68 69 75 77 78
Week 2: 76 73 72 72 75 79 76
Week 3: 79 82 84 84 81 78 78
Week 4: 75 72 68 69 65 63 65

How To Convert ZipEntry Type To File Type

Dec 4, 2014

I'm trying to parse and compare the content of a zip file. However I'm stuck at what SHOULD be a very simple problem, however I can't seem to find a solution. I have done the following:

ZipInputStream zin1 = new ZipInputStream(fin);
ZipEntry ze1 = null;
fin2 = new FileInputStream(fileName2);
ZipInputStream zin2 = new ZipInputStream(fin2);
ZipEntry ze2 = null;
//fin.close();
ze1 = zin1.getNextEntry();
ze2 = zin2.getNextEntry();

Which gives me the first entry of each zipfile as a ZipEntry type object. I have tried getting the path of the file (inside the zip file) and using this to create a File type object. This does not seem to work though I get:

Exception in thread "main" java.io.FileNotFoundException: My DocumentsmetadatacoreProperties.xml (The system cannot find the file specified)
at java.io.FileInputStream.open(Native Method)
at java.io.FileInputStream.<init>(Unknown Source)
at java.io.FileReader.<init>(Unknown Source)

And this is because I get a null return from trying to create the File file1 = new File(correctLocation);

I guess I cannot access the file inside a zip file this way. So my question is how can I make a ZipEntry type object into a File type object?
