Splitting Strings or InputVariables

[dnguyen]

Hi All,

Is it possible to "GRAB" certain, parts of a string, ie. break a string into two parts.

EXAMPLE. input variable, PIN, which has a length of 10 chars. I would like to break this variable up, into two parts.

* Part 1, holds the first 9 chars
* Part 2, the last char

Thanks very much in advance.

Cheers,
David.

The Comment:
It would be in your best interest to get familar with Javadocs because these types of answers are easily found.

The Answer:
What you want is substring. Here is except from the Javadocs for one version of substring (it is an overloaded method):

substring

public String substring(int beginIndex,
                        int endIndex)


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. Thus the length of the substring is endIndex-beginIndex.

Examples:


 "hamburger".substring(4, 8) returns "urge"
 "smiles".substring(1, 5) returns "mile"
 
Parameters:

beginIndex - the beginning index, inclusive.
endIndex - the ending index, exclusive.

Returns:

the specified substring.

Throws:

IndexOutOfBoundsException - if the beginIndex is negative, or endIndex is larger than the length of this String object, or beginIndex is larger than endIndex.

Thanks Wushutwist, I realised that after I posted the thread.

Thanks for your assistance.
