安全的字符串片 [英] safe string slice

问题描述

我有一个字符串，我想要250个字符或更少。

I have a String that I want 250 chars or less. I was doing it the java way, but is there a groovy shortcut for this:

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) 

推荐答案

您可以使用 ：

String shortString = longString.take( 250 )
