Hash:

HashSet set = new HashSet()

set.add("India")

set.add("USA")

set.add("China")

log.info "Set size is : " + set.size()



set.add("China")

log.info "Set size is : " + set.size()



Iterator iter = set.iterator();

log.info "If has next : " +iter.hasNext()

log.info iter.next()

while(iter.hasNext()){

	log.info iter.next()

}

 Result :

log.info "Size of table is " + table.size()

log.info "Name is " + table.get("name")

log.info "Country is " + table.get("country")
