when I am programming let say in VB using Visual Studio, finally I build .exe file that can be run on all Windows by double click.For Java I am using Eclipse and to run those apps I am using run from Eclipse.How I can create a sort of "executable" for my Java app that I would be able to run it by file click on Windows or Linux?
View RepliesI am wondering if there is an easy way to create a java exe(cutable) binary, by packing the JRE and ship it like a compiled C++ bin file? I know JAR is good but, I still prefer to create a standalone install - free exe, no matter if the user has or has not Java installed on her PC.

The problem is that my sorting code can't get access to full array in loop.
Is there any way to pass array to sorting code, or somehow change sorting code?
package pkg06;

public static void main(String[] args) {
double aS =-1;
double aE = 3;

I have tried to get my dinky little program I wrote to be stored as an executable through Eclipse to no avail. It seems I have tried everything else as well, to no avail. I do not want it to go through command prompt, but rather have it be its own entity. As you can probably tell my knowledge of Java and coding is limited, but always willing to expand.

I'm trying to run a command line executable file using java but there is no output. On the task manager a conhost process opens when the application is run. I've tried
1)try {
Runtime.getRuntime().exec("D: est.exe");
} catch (Exception e) {
e.printStackTrace();
}
2)String[] cmd = { "D: est.exe"};
Process p = Runtime.getRuntime().exec(cmd);
p.waitFor();
and
3)//Runtime.getRuntime().exec("D: est.exe", null, new File("D:"));
same thing happens i.e. nothing happens.
I am totally new to java. How to convert the below java code to an executable file?
var intInterval = 0
function importdata(){
filename = "C:1.txt";
AmiBroker1 = new ActiveXObject("Broker.Application" );
AmiBroker1.Import( 0, filename, "custom.format" );
AmiBroker1.RefreshAll();
}
It simply imports numerical data from 1.txt into an application amibroker. Also this import function has to be in a loop of 60 seconds.
I have made a simple h2 db viewer using jdbc and in eclipse it has a horizontal scrollbar so it works and displays correctly.
When I run the jar from cmd it works as it should but the results all go onto new lines so all formatting is lost and it looks.. ugly...
somehow make it so the console has a forced horizontal scrollbar but dunno how.
I am trying to uses classes from a non executable jar called noexec.jar in an executable jar called exec.jar. With no defined manifest in the nonexec jar and a manifest in the exec jar. The folder structure where the jars are held look like so.
ROOT
/lib
|
---nonexec.jar
---exec.jar
With the class path defined in the manifest for the executable jar as Class-Path: nonexec.jar . However every time I run java -jar exec.jar, I get Exception in thread "main" java.lang.NoClassDefFoundError: What even though I am including nonexec in my class path why the classes contained within the jar are not being found?
This is the manifest file
Manifest-Version: 1.0
Class-Path: nonexec.jar .
Main-Class: start
how can I got about sorting an array that contains more than one value in a single element. Such as my array below has 4 values under one element. I know how to sort elements with single values however, slightly confused on this.

I got this code from wikipedia when trying to learn about the radix sort algorithm now I understand that the algorithm sorts by significant digits but it's the code that I'm not too sure about for instance the series of for loops at the bottom what exactly is going on there and why is it mod by 10? Also why are there three different integer arrays a, b, and bucket?
public static void radixsort( int[] a, int n) {
int i;
int digit = 1;
int[] b = new int[n+1];
for (i = 1; i < n; i++)
if (a[i] > a[0])
a[0] = a[i];

I am trying to code a program that orders 5 random numbers from high to low with the basic coding i know (im starting to learn theory of methods... so you can imagine) When i run the code i cant get all 5 numbers ordered but my logic says the code is right although it's pretty confusing.
I know you could code in a simpler way but first i wanna get it as it is right now. When i debug (on my own way cause i dont know how to actually use it) shows line 72 with yellow color.

I have been looking around and I cannot seem to find which algorithm java uses for its sort method. Merge, sort etc.
While I am on the topic BinaryTree is a balanced heap right?
Are there any libraries for depth or breath first search?
Is the ArrayList a double linked list?
I've playing around with linked lists and methods for sorting. So far I've tested the iterative sort, insertion sort, quick sort and they all worked perfectly. Now, I am trying to implement merge sort that would take a linked list of jobs and sort them according to their priority. I found a few solutions on the web, of which I am trying to implemented this one: LeetCode.
My system is a simple one, I do have a linked list of print jobs, each of which has the priority. The following code should sort my print queue and return the link node of the first sorted element. Here's the code.
//defining a job that has priority
public class Job {
private int priority;
[Code]....
The problem I've been trying to solve is that I am getting the stack overflow at line
ListNode<T> h1 = mergeSort(left);
meaning that I am getting into a loop somewhere down through the process of breaking the linked list into half, half or halfs and so on.
I have to count the comparisons in the quick sort. I have done it by using a global variable. But I am stuck in doing it recursively.
This is my code.
import static java.time.Clock.system;
import java.util.Arrays;
public class test {
/**
* The swap method swaps the contents of two elements in an int array.
*
* @param The array containing the two elements.
* @param a The subscript of the first element.
* @param b The subscript of the second element.
*

I am working on a card game and for lack of better terms, have royally screwed up my files. I do still have an executable jar that I would like to go back to if possible and try to redo what I messed up. What I was able to do was to use WinRAR and get ?encrypted? class files. Something that is obviously not editable. How can I go about converting these back to editable java files, if possible?

I am new to JAVA. I need to execute a program, based on the OS. If I am on Mac, the program is a .x and if It is on Windows the program is .exe. The program also requires a line of commands attached to it (i.e. relap5.(x) or (exe) -i inputFile -o outputFile -r restartFile -s stripFile
Here is my coding
String in = " -i ", tfIntdta.getText();
String rst = " -r ", tfRstplt.getText();
String out = " -o ", tfOutdta.getText();
String strp = " -s ", tfStpdta.getText();
if tfStpdta.contains(".csv")
String run = in, rst, out, strp;
else
String run = in. rst, out;
// I want to execute either a .x file or .exe file, depending on if I am
// running the app on windows or mac
run relap5.(x) or (exe) (string run goes here)
I made a project in eclipse and exported it with libraries into a jar file.
Now I need to obfuscate that jar file so it can't be reverse engineered or anything.
I just need something basic. Just where I put the jar file as input and it will output another jar file that is obfuscated.
I looked at proguard but it looks complex for something like this. I don't want to be spending ages making config files or anything... What I should use?
Embedding an executable .jar file on a webpage. I am not a programmer and we use Blackboard Publish to package our Blackboard sessions into a standalone executable .JAR file which gives the user the full Blackboard experience. We want to embed this file on our webpage, so I did some research and I understand I have to use a Japplet (?). I have tried putting the basic (J)applet code I found on the web (modified of course) onto the webpage (see code below) but I get a 'ClassNotFoundException' error. I don't have the ability to define the files that are in the .JAR created by Blackboard Publish. How I would go about embedding this file? I can look at the files within the .jar with Winzip but there seem to be loads of .class files and I am unclear which one my webpage is trying to find!
<APPLET CODEBASE="/Blackboard/" ARCHIVE="test.jar" CODE=test.class WIDTH=140 HEIGHT=45>

how run the executable jar files using JButton from another class file.I need, when i click the button then the executable jar file should be and display the output.
View Replies View RelatedI have a little application that I made, it requires that I save data to a file in data/coins.cdp. When I run the application with java myProg in the terminal everything is correct, when I create the executable jar and run java -jar myJar.jar or ./myjar.jar everything also works. Even if I copy the jar to a different location, and run it through the terminal, it still works fine. Things get weird through when I copy the jar to a new location and double click on it, because then no folder gets created and no file is written.
Why is that?
I have an executable jar file that I decompile using androchef. I have to use androchef otherwise I get to many errors especially with jd-gui. I need to know how to export the files after I have decompiled them with androchef so that I can edit a file then send to netbeans and rejar.
View Replies View RelatedI have one Project -"A".Inside of that I use, .XLS to read data.
