Converting a string to int in Groovy

Question

I have a String that represents an integer value and would like to convert it to an int. Is there a groovy equivalent of Java\'s Integer.pars

Answer 1

I'm not sure if it was introduced in recent versions of groovy (initial answer is fairly old), but now you can use:

def num = mystring?.isInteger() ? mystring.toInteger() : null

or

def num = mystring?.isFloat() ? mystring.toFloat() : null

I recommend using floats or even doubles instead of integers in the case if the provided string is unreliable.
