Groovy排序字符串asc

Question

如何按升序对数组中的字符串名称进行排序。

我尝试了排序方法，但无法按名称排序。

def words = [“orange”，“blue”，“apple”，“violet”，“green”]

我需要达到这样的目的：

[“apple”，“blue”，“green”，“orange”，“violet”]

提前谢谢。

Answer 1

["orange", "blue", "apple", "violet", "green"].sort()

Answer 2

def words = ["orange", "blue", "apple", "violet", "green"]

["orange", "blue", "apple", "violet", "green"].sort({ a, b -> a[0] <=> b[0] } as Comparator )

您还可以根据要求更改索引
