HashMap에서 순서대로 key 값이나 value 값 가져오기

import java.util.HashMap;

import java.util.Iterator;

import java.util.Collection;

HashMap hasm = new HashMap();

hasm.put("key1","value1");

hasm.put("key2","value2");

hasm.put("key3","value3");

Collection k = hasm .keySet();

Iterator itr = k.iterator();

while(itr.hasNext()){

System.out.println("=======key========"+itr.next());

}

Collection v = hasm .values();

Iterator itrv = v.iterator();

while(itrv.hasNext()){

System.out.println("=======value========"+itrv.next());

}
