Re: Array Help

Just a reminder that you can't directly change the characters in a String.
So be careful of thinking you can extract the middle of a string and
replace it with something else... takes a few more steps in Java.

Michael,

Is this something that might work?
----
String str46chars = "This is a string that is forty six characters.";
String str5to9;

str5to9 = str46chars.substring(4,10);
----
The first parameter is where you want to start the substring from (zero
based indexing) and the second parameter is the ending position + 1.
From the api docs on this form of String.substring():

"Returns a new string that is a substring of this string. The substring
begins at the specified beginIndex and extends to the character at index
endIndex - 1"

Best of luck,
     Tom H-C
