Processing a user's input?

Question

I am getting user input on the column, row number and data they want to put in that place. How would I go about breaking the user input into pieces ? The user input will always be in the COLUMN ROW DATA format so is there any delimiter statement that I can use ?

Post what you have tried so far, a sample of the input, and describe specifically what is not working as you want it. — Mat

@Ashley Your question is a bit vague. Could you edit it for clarity? Pretend you've never seen your application before, or know anything about the problem at hand. Your question needs to explain both things. — user50049

okay so like I take in user inputs from the user and sometimes things are optional. Like A user can input find column# hello so it would go find in the column# the user gave the word hello. but a user can say find hello. so I have to process user input according to what the user gave me. — Ashley

If your user input is a string in the format:

<col> <row> <data>

You can use the split() method on the space (" ") to get an array of strings.

For example

input = "3 2 100";
inputs = input.split(" ");
column = inputs[0];           // "3"
row = inputs[1];              // "2"
data = inputs[2];             // "100"

If this isn't what you're looking for then please elaborate your question.

if it there is a lot of spaces between them like 3 2 100 it wouldn't matter ?
