I need to execute a perl file from a resource folder, So that i can able to run the perl file after changing the project to a jar file. And also i need to pass an argument also.
I'm getting an IllegalArgumentException returned when I try to get a file using guava library.
I previously had the function working when the file was in a different location, before I switched to running JBehave, my steps run but it fails to find the resource, even after I've moved it.
The code being executed is (this worked previously before using JBehave):
The file I'm looking for is in the root folder for src/main/resources and also src/test/resources, previously I had it within a completely different location before I switched over to JBehave. I've tried it within a subdirectory in the same locations too.
I've recently updated the pom.xml to try to include the location required.
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]...
these continue for about 40-50 entries, they are not seperated by a blank line though i had to add those so it would display correctly, each entry is on its own line with name seperated with spaces, then price after a comma, then quanity after the second comma.....

and then here is the data from the text file that i must extract to use to create product objects.

I have a CSV file with 16K entries of a data table. Does Java work well with CSV file? So I found this code. And it seems its quite easy to read in the data I need. Say for example if I wanted a loop to randomly pick the first field of a specific line in the CSV data table. How would i go about coding that??????
The CSV looks like the above. and I basically would like to read in the Hand to get it to show in a text box and then randomly have the program ask me to correctly identify the True/False return for one of the SB/BB/UG/MP/CO/BN columns.
how to get the first few hex symbols of a file in java, for example if i input a pdf into my coding i want my program to output, e.g "25 46 44 38" ....
I have been able to print out the hex of a whole file but not managed to set a maximum read limit so that my code only takes a certain amount of values ....
I am implementing a recursive descent parser that recognizes strings in the language below. The input should be from a file "input.txt" and output should be to the console.
The grammar:
A -> I = E | E E -> T + E | T - E | T T -> F * T | F / T | F F -> P ^ F | P P -> I | L | UI | UL | (A) U -> + | - | ! I -> C | CI C -> a | b | ... | y | z L -> D | DL D -> 0 | 1 | ... | 8 | 9
An example session might look like this:
String read from file: a=a+b-c*d
The string "a=a+b-c*d" is in the language.
String read from file: a=a**b++c
The string "a=a**b++c" is not in the language.
Java Code: /**
* The Grammar * A -> I = E | E *E -> T + E | T - E | T *T -> F * T | F / T | F *F -> P ^ F | P *P -> I | L | UI | UL | (A) *U -> + | - | !
[code]....
My current output looks like this:
Java Code: The string read from file: a=a+b-c*d
The string "" is not in the language. mh_sh_highlight_all('java');
So it seems to be reading the input file correctly. My error seems to be on this part
I am trying to read a content of file downloaded from ftp and return it as a String. This is what I use:
Java Code:
import java.io.BufferedInputStream; import java.io.IOException; import java.io.InputStream; import org.apache.commons.net.ftp.FTPClient; public class Test { public static void main(String [] args) throws IOException{ FTPClient ftp = new FTPClient();
[code]....
The code does not work, although all the links are correct.
I have to read from a file that is formatted like that :
name status friend END name status friend END .. etc
could be more than one line of friends, which where I have my problem. I can't get it to check if after the friend name the word "END"
I have tried to write a while loop inside the main while loop but it didn't work, and now I have tried to check that in a separate function which it also failed, thats my two while loops
BufferedReader br = null; FileReader fr = null; int getLine = 0; try { String line; fr = new FileReader(fileName); br = new BufferedReader(fr);
[Code] .....
Most of the time I got nullPointerException or missed up order for printing the file !!
I've looked at multiple sources and everyone is saying different stuff. Which one should I be using? FileWriter/FileReader, other people was saying PrintWriter, and one even said : "Formatter" which is the one I'm doubting mostly. My purposes for writing files is for like saving maps, saving high scores, etc.
I am trying to read from a text file that has that contains a list of stock tickers and pairs letting the user choose a ticker and provide analysis of stock. Given a ticker from the user provide
1) the max price, the min price and the avg price of the stock from all lines in the file. 2)Additionally the user should be able to find the stock with the highes price as well as the lowest price in the list. 3)lastly the user should be able to specify a different filename for the stock file.
Im trying to do part 1 and I am having trouble trying to read the whole text file and outputting the stock price with the max,min and avg. Am I heading towards the right track at least? Keep in mind I have just attempted trying to read the text file I have and not tried to find the max or min or avg Right now my code is crashing when I enter the stock ticker that is my primary concern.

Write a program that extracts words from a file. For the purposes of this program, a word is defined as a series of adjacent letters. Only print words that are at least four and no more than 12 letters long. Print each word on a different line.
The program should read the name of the file from the keyboard.
I need to get the filename from the user for this particular program. Usually I would have the name of the file prewritten into the source code like this....
Scanner input = new Scanner(new File("gettsy_burg.txt");
I tried different ways but I just can't seem to figure it out.... I guess what I'm really asking is how to rearrange Scanner input = new Scanner(new File("gettsy_burg.txt"); since I want the user to input the filename instead of the filename being prewritten by the programmer(me).
This is what I have so far to let the user for input....
Scanner keys = new Scanner(System.in); System.out.println("Enter the filename: "); String fileName = keys.nextLine(); keys = new Scanner(new File(fileName));

I have accountsData.txt file in my default package, this is the file it should be writing to and reading from.
There is an ATM class, which has the main in it. From here the program is supposed to work like an atm, you type in your account number and can withdraw or deposit. It is supposed to then write the changes to the file.
//Read from a file. public void loadAccounts(String inputFileName) throws IOException { Scanner fin = new Scanner(new File(inputFileName)); // Variables to store the values.[/color] int account = 0; double balance = 0.0;
Im trying to read a file called m1 and put that information into a 2-D array with the first two numbers being the size of the array i was able to set the size of the array but how do i populate array?
import java.util.Scanner; import java.io.*; public class test{ public static void main(String [] args)throws IOException{ Scanner fr = new Scanner(new File("m1.txt")); String line = fr.nextLine();
So I have a text file, and I want my Java program to store names from the text file. How do I do that? This is what I have so far.
Java Code: import java.util.Scanner; import java.io.File; BingoCard[] cards = new BingoCard[n]; //Array of BingoCard objects, n being the length of the Array Scanner sc = new Scanner(File("Names")); //Names is the name of the file for(int c = 0; c < cards.length; c++) cards[c] = new BingoCard(sc.nextLine); mh_sh_highlight_all('java');
Here's the constructor.
Java Code: private string myName; public BingoCard(String name) { myName = name; } mh_sh_highlight_all('java'); Whenever I compile, I get this error message.
I'm trying to print the number of vertices in a text file on a graph which is the first integer in the file and then the type of graph is an undirected graph for a 0 or a 1 for a directed graph. Right now I'm just trying to print the number of vertices which is a 6 in the text file.
Here's the text file:
6,1 0,2 0,4 1,4 1,5 2,1 2,3 2,5 3,2 3,4 4,1 4,5 5,1 5,3 5,2 Im getting the following error: Exception in thread "main" java.lang.IndexOutOfBoundsException: Index: 6, Size: 0 at java.util.ArrayList.rangeCheckForAdd(Unknown Source) at java.util.ArrayList.add(Unknown Source) at Vertices.main(Vertices.java:21)
Then I need to know how to go about reading the next line in the file, do you read it with the nextLine and put it into an arrayList or do I read each index in the graph?
public class Vertices { public static void main(String[] args) throws Exception { Scanner inFile = new Scanner(new File("graphs.txt")); // Read the number of vertices String line = inFile.nextLine(); ArrayList<Integer> list=new ArrayList<Integer>(); String[] data=line.split("[\,]"); int numberofvertices=Integer.parseInt(data[0]); int typeOfGraph=Integer.parseInt(data[1]); list.add(numberofvertices,typeOfGraph); System.out.println("The number of vertices is " + numberofvertices); } }
The following program should read in a file on my desktop (I have the path set in Netbeans to that location) and produce a Histogram. Instead I am receiving this error.
Exception in thread "main" javax.imageio.IIOException: Can't read input file! at javax.imageio.ImageIO.read(ImageIO.java:1301) at Histogram.main(Histogram.java:9) Java Result: 1 BUILD SUCCESSFUL (total time: 0 seconds)
Here is the code for the Histogram:
