Converting a String into an int
« on: May 26th, 2004, 5:01am » |

Hi All,
I am new to programming, so I apologise if this subject is a simple one. I was unable to find an example of this in the documentation and discussion boards.
I am building a very basic visualization tool and am looking to transform numbers read in from a text file -- as strings via loadStrings() -- into integers. Seems that most of the data conversion methods -- like int() -- only work with primitive data types. How is this transforation usually performed?
Also, any good suggestions on where I can find more (basic) information about parsing and manipulating content read in from external files?
thanks!
B

coverting an entire string into an integer doesn't make a whole lot of sense.
I think what you're looking for is splitting the string into an array of characters, then converting them all into integers while you're at it?
check out splitstrings()

Thanks for your help... greatly appreciated... I am not looking to convert an entire string of text, just numbers read in from a text list.
splitStrings() will be very helpful in chunking down my fields, but I am still looking for a way to turn these characters into integers.
I have currently solved this by using Float.valueOf() then using int() for conversion. Is there a better way to do this?
thanks

mflux's answer is kind of right, but a little wobbly 
Take a look at splitInts() which does what you're asking...
http://processing.org/reference/splitInts_.html
(Oh, and the pure Java way would use Integer.parseInt() instead).

Hi Tom,
Thanks for your (and others') always helpful replies. I think that the added reference to an equivalent or similar java method/class (as you did here) is especially helpful.
