查找大于SortedMap中的第一个值(Finding the first value greater than in a SortedMap)

我想知道有什么更好的方法来找到大于SortedMap中的输入值的第一个值，而不是循环遍历下例中的所有值。或者，如果SortedMap是用于此的最佳结构。

这可以通过谷歌收藏来实现吗？提前致谢

public class mapTest { public static void main(String[] args) { SortedMap<Double, Object> sortedMap = new TreeMap<Double, Object>(); sortedMap.put(30d, "lala"); sortedMap.put(10d, "foo"); sortedMap.put(25d, "bar"); System.out.println("result: " + findFirstValueGreaterThan(sortedMap, 28d)); } public static Object findFirstValueGreaterThan(SortedMap<Double, Object> sortedMap, Double value) { for (Entry<Double, Object> entry : sortedMap.entrySet()) { if (entry.getKey() > value) { // return first value with a key greater than the inputted value return entry.getValue(); } } return null; } }

I'd like to know what is there a better way to find the first value greater than an inputted value in a large SortedMap instead of looping through all values in my example below. Or if SortedMap is a the best structure to use for this.

Could this be achieved using google-collections? Thanks in advance
