groovy - 安全的字符串切片

我有一个不超过250个字符的字符串。我正在用Java的方式来做，但是这有一个俗套的捷径:

def longString = "This is my really long string.This is my really long string.This is my really long string.This is my really long string.This is my really long string.This is my really long string.This is my really long string.This is my really long string.This is my really long string.This is my really long string.This is my really long string.This is my really long string.This is my really long string.This is my really long string.This is my really long string.This is my really long string.This is my really long string.This is my really long string."
def shortString = "This is my really short string."

#ideal would be something like:
return longString[0..250]
#versus how i currently have it
#how can i simplify this one...
return shortString.size() < 250? shortString: shortString.substring(0,250)

最佳答案

You can use take :

String shortString = longString.take( 250 )
