public static void main(String[] args) {
LinkedHashSet Lhst = new LinkedHashSet();
Lhst.add("10");
Lhst.add("11");
Lhst.add("12");
Lhst.add("13");
Lhst.add("14");
Lhst.add("15");
Lhst.add("16");
System.out.println(" The LinkedHashSet contains the elements :"+Lhst);
Lhst.clear();
System.out.println(" All the elements from the LinkedhashSet is removed:" + Lhst.isEmpty());
// TODO Auto-generated method stub
}
}
The LinkedHashSet contains the elements :[10, 11, 12, 13, 14, 15, 16]
