Hello,
I am new to Java. I run the test code for KMeans (with all the packages in the right folder as mentioned in the installation procedure). The code compiles error free and Builds the XML file too; But the needed results are not written to the output file given in the path.
The code:

package ca.pfv.spmf.tests;

import ca.pfv.spmf.clustering.kmeans.AlgoKMeans;
import java.io.IOException;
import java.io.UnsupportedEncodingException;
import java.net.URL;

public class MainTestKMeans_saveToFile {

public static void main(String []args) throws NumberFormatException, IOException{

String input = fileToPath("configKmeans.txt" );
String output;
output = "C:\\patterns\\clusters.txt";
int k=3;

// Apply the algorithm
AlgoKMeans algoKMeans = new AlgoKMeans(); // we request 3 clusters
algoKMeans.runAlgorithm(input, k);
algoKMeans.printStatistics();
algoKMeans.saveToFile(output);

}

public static String fileToPath(String filename) throws UnsupportedEncodingException{
URL url = MainTestKMeans_saveToFile.class.getResource(filename);
return java.net.URLDecoder.decode(url.getPath(),"UTF-8" );
}


}

I tried explicitly creating the path and the file, but the code still wont write the result into it.
Please reply with a solution to this.
Thanks in advance

Hi,

Welcome to the forum. It should works. I tested it on my computer and it works.

Could you tell me what is shown in the console when you run the algorithm? Is there some errors?

Are you using Eclipse? Please provide me some more information so that I can help you.

Best,
Philippe

I tried it on both the IDEs- Eclipse and Netbeans.
I get 0 errors.
But when I search for the output in the specified path, I get nothing. :|
What could be the reason?

There could be a problem with administrative rights on that drive (C:\) or folder? Maybe try changing the path for another path.

You could also update your Java installation...

I mean, it must be some kind of problem like that, because many people use this code and it works.

Philippe

Changing path doesnt help, also am using the latest Java update.
Guess there is some other configuration fault that I cant figure. Thanks for the time, great work!

Thanks. Hope you can find out what the problem is....

If you find out, please let me know.

Philippe

Works fine on my other computer, so it was some system inconsistency I guess, will figure it out later.
Thanks

Glad to know that!

Philippe
