Stupid parsing question

[Lucky75]

Hey,

I'm being an idiot and I can't figure out how to do parse and get an integer from a string. Could someone give me an example please?

Something like:

"The action you going to take costs 5 dollars, and will take up to 3 days to complete"

How would I store the value "3" as an integer? The "5 dollars" can vary.

Thanks!

To convert a string to an int use Integer.parseInt(..)

Of course you have to extract the string representation of the number from the string first. You can use a regex to do that.

Yeah, thats the part that I don't know how to do, the regex part

hmmm...

Strting text = "The action you going to take costs 5 dollars, and will take up to 3 days to complete";
String[] strin;
String delimiter = " ";
strin = text.split(delimiter)
int number = Integer.parseInt( strin[strin.length-4] );

This should work, assuming the number is always the 4th element from the rear side of the string.

Probably with some modification this would also work
