I want to find the ports present in the Windows 7 and I have written code for it. It successfully compiles but there is no output. I have Compiled in Netbeans

Here is my code:

import java.util.*;  
import javax.comm.*;

public class PortLister {  
    public static void main(String[] args) {  
        Enumeration e = CommPortIdentifier.getPortIdentifiers();  
        while (e.hasMoreElements()) {  
            System.out.println((CommPortIdentifier) e.nextElement());  
        } 
    }  
}
