    <p>I have a folder with 1 <code>ThMapInfratab1-2.exe</code> file and 3 <code>.txt</code> files. If you run <code>.exe</code> file in any way(through command prompt,just double click and through any language) one Icon will be appear on <code>Taskbar</code>.</p> <p><img src="https://i.stack.imgur.com/nDhRm.jpg" alt="enter image description here"></p> <p>My <code>.exe</code> will be run 2-3 minutes.</p> <p>Know I want to run these <code>.exe</code> file using <code>Java</code>.I found How to run <code>.exe</code> from <code>Java</code> technology.</p> <p>My concept was, first I will find <code>.txt</code> file Names from the directory.finally I will get like this.</p> <pre><code>List&lt;File&gt; fileNames={"File1.txt","File2.txt","File3.txt"}; </code></pre> <p>Know I want to run my <code>.exe</code> file 3 times because my <code>fileNames</code> length is equals to <code>3</code>.For this I wrote the following code.</p> <pre><code> //ExeFileProcess Function public void ExeternalFileProcessing(String DirectoryPath,String exeFileName,String inputFileName) throws IOException { String executableFileName = DirectoryPath+"/"+exeFileName; String inputFile=inputFileName; ProcessBuilder processBuilderObject=new ProcessBuilder(executableFileName,inputFile); File absoluteDirectory = new File(DirectoryPath); processBuilderObject.directory(absoluteDirectory); processBuilderObject.start(); //processBuilderObject.wait(); } //Main Function code. public static void main(String[] args) throws IOException { ExternalFileExecutions ExternalFileExecutionsObject=new ExternalFileExecutions(); for (int fileIndex = 0; fileIndex &lt; fileNames.size(); fileIndex++) { ExternalFileExecutionsObject.ExeternalFileProcessing("C:/Users/Infratab Bangalore/Desktop/Rod","ThMapInfratab1-2.exe",fileNames[fileIndex ]); } } </code></pre> <p>I evaluated above code, at a time 3 <code>.exe</code> processes are started.But I don't want like that. I want to run <code>.exe</code> file one by one(we need to monitor, whether the previous <code>.exe</code> process was done or not. once it's done it allows to next Iteration).</p> <p>I tried with <code>Wait()</code>.but it's not working.</p> <p>I guess, for this I need to add some code in my <code>ExeternalFileProcessing()</code>. But I didn't get anything.</p> <p>can anyone suggest me.</p> <p>I hope, you understand, what My problem.</p>

    2. CO@PhilippSander Actually I have only one problem,but I want to learn `Java`.so I divided my problem into function wise and I am trying to figure it out. But in every function I stuck in somewhere, I am asking help from `StackoverFlow` guys.because these guys are ready to help to anyone(even for starting guys). Finally I reached final stage of my problem. for this I am working from yesterday. because everytime, I don't want to base on any one. so first I am trying using Google, If I face any problem I am posting question in `StackoverFlow`.

Querying!

 
Guidance
A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
