I 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.
View Replieswhen 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 Replies View RelatedI 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.
View Replies View RelatedI'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
Here is the problem:
Start with the tree.java program (Listing 8.1) and modify it to create a binary tree from a string of letters (like A, B, and so on) entered by the user. Each letter will be displayed in its own node. Construct the tree so that all the nodes that contain letters are leaves. Parent nodes can contain some non-letter symbol like +. Make sure that every parent node has exactly two children. Don’t worry if the tree is unbalanced. Note that this will not be a search tree; there’s no quick way to find a given node. You may end up with something like this:
It also says all Letters must be Leaves
Now I had it almost similar to that picture, but it wasn't right. So ive been working on it but im getting some very strange (and frustrating) output from the following methods.
Ive included the display method just for reference. The book told me to use it so I haven't edited it. I believe my main issue is with my (incomplete) insert() method. The output goes into an infinite loop despite having a return statement break the while loop when a character is inserted.
The way I see to solve the problem is just add a (+) whenever a new subtree needs to be created. Say I add A and B, then it first creates a subtree at the root with a (+) and afterwards lists A and B as its leaves. If I insert a C, it should be able to simply move to the right child of the root and deposit the C there.

This code is for a GUI Java program that is supposed to convert back and fourth between two numbering systems. For example, binary to decimal or decimal to binary. I have created methods for some of the conversions however, I could successfully develop a method to convert from hex to binary. If you plan to run it to see what happens to the current method that I made please know that in the GUI the north end from left to right is as follows.
The textfield is for user entry of any type of data. The first combobox is for the user specifying to the program what type of data he or she entered. The second combobox is for the user to choose what he wants that data converted to. The button is to convert it. The south side has a textarea that gives out the results. Please note that only some of the conversions work so far. There are comments in the code to label which methods do what converisons. Need to find a method that will convert from hex to binary, what is wrong with the current method.

View Replies View Related I have written a code to get all the nodes below a current Node and it is working but I need to get it to look better if possible. To get the number of nodes below I have created an Array List, which I then go to the first Node below and add all the people to the Array list on the same level till I get to the end of the level, then I go down again until I cannot go down any more. Is there a way I can have my code without having to use an array List? I have put my code below. The brieff about the tree is that you have a parent and below the Parent are children who can have brothers and sisters next to them and after that they also have children below that. The method is trying to find the number of children below any given child

No matter how many times I keep rewritting the testInsert method I get a chock full of errors.
in Operator/Literals, it says "There is no literal representation for binary numbers in C, C++, or Java." seems "0b11001" could reprensent binary numbers?
int i = 0b100;
System.out.println(i);
the output should be 4.
I have a unix program that simulates an accident evolving as a function of time and produces two files. I will focus on the first file before getting to the second. This first file has five output variables/vectors (velocity vs time, pressure vs time, etc), which are selected as part of the simulation input. These are the variables I have to put into Excel if I want to view the transient graphically. Where it gets tedious is that, if I want to view a different set of five variables, I have to rerun, extract, put these in Excel to plot. There can be lots of variables needed to properly characterize the accident.
The second file produced is a really large binary file. This file contains all the information that I'd need, precluding the need to rerun to view a different set of output variables. This is the file that seems tailor-made for a Java or something to be able to extract the information. That is, it seems like Java could be used to do this work: extract variable information from the large binary file. Eventually, I would like to plot it too and I know I could use Java there.
I think my steps are:
1) understand the format of my binary file
2) reconfigure the binary file for use with java (is this demuxing?)
3) learn java programming for this application: extracting information to produce something like a .csv file with time on the leftmost column and variable information populating the rest of the columns.
I have made a Java Binary Encoder and Decoder program and, to date, this is the program I have spent the most time developing.

I Write a Java program to parse a syntactically correct arithmetical expression and produce an equivalent Expression TREE. Remember, in an expression tree the terminal nodes are variables and constants, and the interior nodes are operators (such as +,-,*,/).
For instance the expression: (1 + 2) * 3 can be represented by the following tree:
INPUT Expression
(1 +2)*3
POSTORDER Expression
1 2 + 3 *
TREE [root=asd.reg.Node@56ddc58]

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?

Assuming like, a main class is currently running and that is what's inside the manifest file as the main class inside that executable jar..
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!
