Java/Groovy - Sorting Map on Value

Sorting Map on Value

map = new LinkedHashMap();
map.put('a', 7);
map.put('b', 6);
map.put('c', 9);

list =new LinkedList<Map.Entry<String, Integer>>( map.entrySet() );
Collections.sort( list, { Map.Entry o1, Map.Entry o2 ->
	return (o2.getValue()).compareTo( o1.getValue())
})

result = new LinkedHashMap<String, Integer>();
for (Map.Entry entry : list){
	result.put( entry.getKey(), entry.getValue() );
}

print result
