How to Sort HashMap or Map in java?

/* Sorting Map and return LinkedHashMap, u can send HashMap implemented Object but it should a map like
Map map = new HashMap();
ma p = sortHashMapByValues(map);
*/
public LinkedHashMap sortHashMapByValues(Map passedMap) {
List mapKeys = new ArrayList(passedMap.keySet());
List mapValues = new ArrayList(passedMap.values());
Collections.sort(mapValues);
Collections.sort(mapKeys);

LinkedHashMap sortedMap =
new LinkedHashMap();

Iterator valueIt = mapValues.iterator();
while (valueIt.hasNext()) {
Object val = valueIt.next();
Iterator keyIt = mapKeys.iterator();

while (keyIt.hasNext()) {
Object key = keyIt.next();
String comp1 = passedMap.get(key).toString();
String comp2 = val.toString();

if (comp1.equals(comp2)){
passedMap.remove(key);
mapKeys.remove(key);
sortedMap.put((String)key, val);
break;
}

}

}
return sortedMap;
}
