Any API that can call package list?

Question

I want to get package's names that current jdk version has programmatically
for example,
String[] packageList= UnknowClass.getAllPackageNamesUnknowMethod();
If it's not possible please reply as it is.
Thank you.

Answer 1

perhaps its not as hard as it seems. this returns 23 packages to me, might be fun to mess around with .. mm? mmm.
class packs {
     public static void main(String[] args){
          Package[] packages = Package.getPackages();
          int sz = packages.length;
          for(int x = 0; x < sz; x++){
               System.out.println(x+":\t"+packages[x].getName());
}
