Added comma separated on the foreach Velocity loop

Question

What should I added to the following foreach loop (Velocity codes) to get the final result like appNames=A,B,C

   #if($approval.has()) 
   #foreach($item in $approval.rejected)
   #set($appNames =$item.appName)
   #end
   #end

Thanks

Answer 1

Just simply do add separator to it in the loop and String concatenation

#if($approval.has()) 
#set($appNames ="")
#set($separator="")
#foreach($item in $approval.rejected)
#set($appNames  =$appNames  +$separator +$item.appName)
#set($separator = ",")
#end
#end

appNames= $appNames

output

appNames= A,B,C
