Taking a string, and putting the characters into an array

I'm trying to figure out how to put a string into an array so that each letter is put in a spot.

It would take a word like hello and have

test[0] = "h"
test[1] = "e"

and so forth.

The reason I'm trying to do that is because I want to take the numbers that someone could enter and base them off of the numbers column, so that the tens provide a response specific to a prefix, like twenty or thirty, and the ones column is specific to that.

Thanks in advance.

String has a method called toCharArray that will return a char[] with each character of the String.

How are you going to use the contents of the test array? Your example shows test to be defined as: String[] test;
The String class has several methods for getting at individual characters.
Scan thru the API doc to see if any of them is what you need.

Couldn't you also use the charAt() and length() methods also?

What you can do is put create a variable that will hold the valu of the string, then you can use the temp.length() assuming that temp refer ti the value of String.

Then after that you can use temp.atChar().

Rob has already given the appropriate response here. I think beyond that Logan might be getting confused. Let's wait and see if Logan asks for anymore help.

toCharArray() is the best way to get all the characters of a String into an array.
