Array of strings in groovy
提问by Lucas
In ruby, there is a indiom to create a array of strings like this:
在 ruby 中，有一个成语可以创建这样的字符串数组：
names = %w( lucas Fred Mary )
Is there something like that in groovy?
groovy 中有类似的东西吗？
采纳答案by Chris Dail
Most of the time you would create a list in groovy rather than an array. You could do it like this:
大多数情况下，您会在 groovy 中创建列表而不是数组。你可以这样做：
names = ["lucas", "Fred", "Mary"]
Alternately, if you did not want to quote everything like you did in the ruby example, you could do this:
或者，如果您不想像在 ruby 示例中那样引用所有内容，您可以这样做：
names = "lucas Fred Mary".split()
回答by Dónal
If you really want to create an array rather than a list use either
如果你真的想创建一个数组而不是一个列表，请使用
String[] names = ["lucas", "Fred", "Mary"]
or
或者
def names = ["lucas", "Fred", "Mary"].toArray()
