StringIndexOutOfBoundsException

[Tee Morales]

Hi All,
Getting this error. I ran it through the debugger and I see that it is taking an error on the second field billingUnit = record.substring(9,4);. See how the String is greater than the substring I am indexing. I don't understand how it is taking such an error.

private String status = null;


public GroupSORDate(String record) {
group = record.substring(0,9);
billingUnit = record.substring(9,4);
accountNumber = record.substring(13,7);
enrollmentDate = record.substring(20,8);
billingDate = record.substring(28,8);
status = record.substring(36);
}

I would suggest looking here and here. An important thing to note is the the setup of the substring method:

 
String substring(startIndex, endIndex)

What would "billingUnit = record.substring(9,4);" return to billingUnit?

billingDate = record.substring(28,8);

the problem lies right here:
startindex>endindex

The syntax of the substring function reads:

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.



Hope this helps...

Thanks!

I goofed up.


group = record.substring(0,9).trim();
billingUnit = record.substring(9,13).trim();
accountNumber = record.substring(13,20).trim();
enrollmentDate = record.substring(20,28).trim();
billingDate = record.substring(28,36).trim();
status = record.substring(36);
}
