Launch Windows Directly Into JAVA Based Password Entry System?
Apr 5, 2014 Is it possible to launch windows, specifically 8.1, directly into a java based program which would serve as the password entry screen? That is to say, instead of using the standard windows screen, could a java based alternative be used?
I have the source code used on jurassicsystems.com. I would absolutely kill to have a tweaked version of this system act as my password entry screen. It is literally something Ive wanted to have done for ages, and this emulation finally means it may be possible.

Adding Java Program To Windows Startup Using Bat File
Jan 19, 2015I've added a small program that reads from a .txt file to the windows 8 startup folder using a .bat file ... The problem I have Is I've used relative paths for text files In the program and It doesn't work unless I change them to absolute paths.
The .bat file Is basically java -cp[absolute path to program directory] ReadAFileApp . Is there something (most likely yes!) I'm missing here ?
File System - Managing Secondary Memory Simulated As Byte Array In Java
Feb 11, 2014I and a friend are working with a project to create a file system, who manages a secondary memory simulated as a byte array in Java. We want the file system to be a hierarchical tree structure like in UNIX.
We have come quite far, but the paths are not handled correct. I seem to have mistaken the relative folder ./ for the root folder, but it should mean "working directory folder", ie, where I stand now. That is, if I stand in /dir1 as my "working directory" and make mkdir ./dir2 then should dir2 end up as subfolder in dir1. But with me it appears in the root.

Specifying File Location?
Mar 10, 2014How to specify the file location. One way would be
PrintWriter outputFile=new PrintWriter("A:PriceList.txt");
My problem occurs when I try to specify a file location as show below
//Open an output file that appends data and does not delete it
FileWriter append_data=new FileWriter("C:hello.txt",true);
//Make a file that cvan print data into it
PrintWriter outputfile=new PrintWriter(append_data);
Apparently, I believe this is not the right way to set my own path for the file... How can I specify my file path.
One more question would be that suppose I want to specify the file location on Desktop. What the format for that?

View Replies View RelatedInputStreamReader Looking For File Location
Apr 26, 2014The file (let's call it file.txt) is on the C: of my machine. I'm using :
System.out.print("Where is the file?: "); BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
And looking for the user to enter the location of the file in the console. How do I (the user) enter the path to the file in the console. I have tried everything... "C:file.txt", C:file.txt, and a million other combinations. Nothing seems to work. How does the console expect the file path to be written so it knows how to pick up the file?

Apr 22, 2014I am creating a web application that runs on server X(unix) and it has another unix system mounted on it. I want to generate the file tree structure of this mounted unix file system and show it on to a web application so that users can select a file and move it onto this current unix machine.
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.
Servlets :: File Is Located In Root Directory Of Project But System Cannot Find File Specified
Jan 10, 2015I need to make some operations with a file. I struggle to understand why Apache is throwing this error:
(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.

View Replies View RelatedReading From Text File - Print Linked List On Console
Mar 9, 2015How can i convert this linked list code to a read from input.txt
The first line in the input file will give the elements to initialize the linked list with. Consecutive lines will provide operation instructions.
Your code should read one line at a time. After reading each line, it should perform the corresponding operation and print the linked-list on the console.
If an operation is not possible, it should print "N/A".
Sample input file. Please note, the comments (// ...) are given for explanation, the input file will not have them:
4, 5, 6, 3// First line. This will provide the initial values for the linked list : 4->5->6->3
1, 9// Add a 9 at the front of the linked-list. After this operation the linked-list should be: 9->4->5->6->3
2, 1// Add a 1 at the end of the linked-list. After this operation the linked-list should be: 9->4->5->6->3->1
3, // Delete the first node in the linked-list. After this operation the linked-list should be: 4->5->6->3->1
4, // Delete the last node in the linked-list. After this operation the linked-list should be: 4->5->6->3
5, 11// Delete the node with the value 11 in it. Since this is not possible, it should print "N/A"
5, 6// Delete the node with the value 6 in it. After this operation the linked-list should be: 4->5->3
Sample output to the console:
4->5->6->3
9->4->5->6->3
9->4->5->6->3->1
4->5->6->3->1
4->5->6->3
N/A
4->5->3

class linkedList

protected Node start;

Display Contents Of File In Reverse Order - Output To Console
Jun 24, 2014Create a class that allows the user to select a file and output the contents of the file to the console. Recommend using a text file to display, java files are text files. You may want to put this code in a method to allow you to complete the remainder of this assignment without overwriting your code.
- You should ask the user to enter the full path to your file to make certain you are processing the correct file.
- Modify your code/add a method to display the contents of the file in reverse order. You do not need to reverse the characters on each line but simply output the lines of the file in reverse order.
Hint: read the content of the file into an ArrayList and then traverse the ArrayList.
this is what i go so far.
package classActivity;
import java.io.File;
import java.io.FileNotFoundException;
import java.io.PrintWriter;
import java.util.ArrayList;
import java.util.Collections;
import java.util.Scanner;
public class Select

How To Set Different Java Versions For Different Apps On A Windows PC
Nov 25, 2014I have 2 different apps, one of them is a java desktop app and the other one is a c# web app. which uses java applet in order to e-sign. The problem is desktop java app requires 1.5.0_14 and on the other hand web app. requires 1.7 and higher version of java.
I installed both java 1.5 and 1.7 versions on my PC. In order to run desktop java app., I go to C:Progra~2Javajre1.5.0_14in and run javacpl to disable 1.7 and enable 1.5. Then I make a shortcut to javaws 1.5.0_14 to my desktop and add the jnlp of this java app to the target of javaws shortcut. After those settings, the java desktop app. runs.
Now I need to also run the web app which requires 1.7 java. In order to run this app. properly Java 1.5 should be disabled, 1.7 enabled on the Java Control Panel settings. Problem is when you run this web app. the settings for 1.5.0_14 breaks down, I mean all of the java versions become enabled in javacpl under C:Progra~2Javajre1.5.0_14in directory. If I restart my PC, I need to reset the java versions. Is there a way to make this happen without a pain in the head?
By the way, I tried to use batch files etc. but not succeded.
How To Identify Default Java Heapsize In Windows
Sep 26, 2013Im running an eclipse application in my machine. I have two queries
1. I would like to know how to check the default heap size that the jvm is using to run the application.Im using a windows machine to run the java application. I tried to check the default heap size by the following way
ControlPanel--->Programs--->JavaSetting--> JavaTab -->View Button ---> JavaRuntimeEnvironment settings window ---> Userstab --> Value under RuntimeParameters
But in my system, there is no runtime parameters defined. Is there a command that I can execute via command prompt to check the default heap size in my machine.
2. How to increase the heap size parameter and run the eclipse plugin application from command prompt. For eg: To increase the heap size and execute the jar file we use the below command java -Xms64m -jar MyApp.jar. I would like to know how to set heap parameters and execute my java application which is an exe file. I tried to execute use the below command, but the command prompt doesnot recognise the command
java -Xms512m iepsd.exe
Where iepsd.exe is my java application.
