I have four fields to get concatenated with comma separator but if any of the field is blank, additional comma will not be added.
For example - Var1 + Var2 + Var3 + Var4
If Var1 is blank then output should be
Var2, Var3,Var4
I am using Java 6
I tried to follow the link but getting version issue. Please share solution which is compatible with lower version of java Join comma if not empty or null
