UDF for Date format

Question

Hi,
I want to write an UDF
I want to pass Date as an String in format yyyymmdd.
I want to convert it to mm/dd/yyyy. & pass new date as o/p/
But there is a possibility that i/p Date may come as blank in that case I want to keep output as blank.
Please help

Thanks guys,
I am using this code but get an error
int len;
len = Date.length();
if (len>7)
String year = Date.substring (0,4);
String month = Date.substring (4,2);
String day = Date.substring (6,2);
String f  = month + "/" + day + "/" + year;
return f;
else
return Date;
--- Here when I run this in test mode I get this exception -
Exception:[java.lang.StringIndexOutOfBoundsException: String index out of range: -2] in class com.sap.xi.tf._MM_PSN_EMP_INFO_ method check$[19880517, B1, A1, C1, F1, G1, H1, X1, X1, X1, X1, X1, X1, 07, 5, com.sap.aii.mappingtool.tf3.rt.Context@7ab97403]
