public class Socket {
public static void main(String args[])

try {
// getting permission object
Permission p = getPermission();
// print actions of permission p
System.out.println(p.getActions());
// printing hashcode value of permission p
System.out.println(p.hashCode());
// creating a permissionCollection object and
// printing it
PermissionCollection p1
= p.newPermissionCollection();
System.out.print(p1);
}
catch (Exception e) {
