Is it possible to get a list of installed applications (like the list from the un-install programs) from a windows vista computer with java?

package Vishal;

import com.sun.jna.platform.win32.Advapi32Util;
import static com.sun.jna.platform.win32.WinReg.HKEY_LOCAL_MACHINE;
import java.util.ArrayList;
import java.util.TreeMap;

public class GenerateInstalledApplicationList 
{
    ArrayList getlist()
    {
        ArrayList arr = new ArrayList();
        String [] keys = Advapi32Util.registryGetKeys(HKEY_LOCAL_MACHINE,"Software\\Microsoft\\Windows\\CurrentVersion\\Uninstall");
    String temp;
    for (String key : keys) 
    {
        temp = "Software\\Microsoft\\Windows\\CurrentVersion\\Uninstall" + "\\" +key;
        TreeMap tr = Advapi32Util.registryGetValues(HKEY_LOCAL_MACHINE,temp); 
        if(tr.isEmpty())
        {
            if(!key.contains("Update"))//all the instances of update are not actually installed applications
            {
            arr.add(key);
            }
        }
        else
        {
            if(tr.containsKey("DisplayName"))
            {
                String str = (String) tr.get("DisplayName");
                if(!str.contains("Update"))
                {
                arr.add(str);
                }
            }
        }     
    }
    return arr;
   }}

Just Copy and paste this code it will return all the installed applications only thing you will need is the jna api.
