Java Code To Grab All Files Located Under A Folder
Apr 25, 2014
I am currently using the following Rally API Java code(below...in Java 1.7) to create an object and attach a file to it. This code works fine. But I need the code to be a little less specific and attach all files located under a folder (not just one file). How could one potentially rewrite this code (or use a different constructor/method) to accommodate such a thing? Also additional code how to narrow down results to all files with a creation date >= today.
Where can I learn or how can I, being the most efficient way known to do so, create a folder outside my JAR file with the java source code, this then will copy YAML documents from my JAR file to that folder, then I need to read the YAML documents some way. I'm making an addon for a game, I am using an API that allows you to make a config.yml easily, and add and read entries from it, but I've read that I need to make my own methods to be able to create additional YAML documents.
I don't exactly know what to type in google to perhaps find such a page, but I did try to find a tutorial page about this or something and couldn't.
I've partially figured out how to create a folder, but I have a problem, how can I RETURN one directory to make the folder, I don't want to make the folder in the JAR file I want to make it just outside the Jar file in the same folder that the Jar file is at.
i have to save some particular info of a pdf file info into a database.there are lots of folders with tons of pdf files to be analized and then getting that info saved. make the process incremental? i need the program to stop at some point. and then continue to analize the resting files in the folders (i dont want the program to start all over again from 0 )my ideas are..sorting all the files using apache commons sort (by date) method (iv seen it somewhere) and saving the last file analized in the dabatase to then continue. OR just adding some extra character to the pdf file name that has been analized like for example xx-xxx.pdf to xx-xxxa.pdf.
I am trying to grab a graphical object from an arraylist, and reposition its coordinates on a Jframe when adding it. My program of course deals with strings, and once it sees specific words in my console, some method is called that adds, removes, or otherwises modifies certain objects on screen.
Here I want to say something like move(object[1],xpos,ypos) which will move a certain object from a specified point in the array, and move it to new x and y positions on the JFrame. I use a different class that extends a graphics program, so when I say add(something,x,y) it draws the object onscreen where I want it. These are some relevant, though incomplete, methods that should move an object already painted on screen:
Console class
Java Code:
public void doMoveCommand(String cmd, String arg, String xpos, String ypos) { int x = Integer.parseInt(xpos); int y = Integer.parseInt(ypos); if (cmd.equals("posMake") && arg.equals("star")) { box.moveStar(box.historyG.get(1), x, y); //historyG is an arraylist of GPolygons freeCommand();
[Code] ....
When I say makepos(whatever) I am getting a arraylist out of bounds exception. How I might be able to accomplish moving objects already on screen?
Means like in php we can install xampp and there for a new app we need to create a folder in htdocs folder...and after that , that folder works like a app.
I have observed a strange behavior in my system. whenever i installed jdk1.8.0_11, the issue is that, unknowingly the 'Bin' folder which is underneath 'C:Program FilesJavajdk1.8.0_11' is emptied. When and how it is emptied i wouldn't be knowing. I have to download the entire jdk every time in order to have Bin folder content every time.
I am using my office laptop, Is that the problem? I mean office IT department have any control on this? If so , what can i do to over come this problem?
I have looked over other people code relating to files that are related to my actual studies in class. My teacher hasn't worked on a lot of file problems so I want to gain some understanding on it.
1.) I have this class with variables declared
import java.io.*; public class FileDisplay { private String filename; FileWriter outputfile; File Inputfile;
I'm aware that having a private variable would not allow that variable to be accessed outside the code. Vice versa, public variable would do that. The FileWriter and the File Inputfile is something I don't understand, especially have them in classes. What is the purpose of them?
2.)
public class FileDisplay { private String filename; FileWriter outputfile; File Inputfile;
[Code] ....
I have made this code here that opens the output and input file. If I make another method, how would I display the text onto that same file. Hard to clarify for me, but in each method do I just keep creating :
I am trying to apply for a job in testing the following java application.I have received a tool written in Java and I need to run it with the command line:
I am developing an web application with servlets and jsp. I have an issue to store images. I am storing images in folder and their relative path's in mysql database.
When I retrieve path from database then using <IMG> tag i have displayed image like:
In the following piece of code Iam trying to display the the loan amounts of the various loan objects located in a binary file. Iam trying to do his using getLoanAmount() in the loan class. the program is compiling but nothing is showing up on he console.
Program import java.io.*; public class Exercise19_06 { public static void main(String[] args) throws ClassNotFoundException, IOException { ObjectOutputStream output = new ObjectOutputStream( new FileOutputStream("loan.dat"));
