in velocity can you iterate through a java hashmap's entry set()?

Question

Can you do something like this in a velocity template?

#set ($map = $myobject.getMap() )
#foreach ($mapEntry in $map.entrySet())
    $mapEntry.key()&         


        

Answer 1

Here the Value

itemsValue={data1=1,data2=2,data3=3}

So , we need to iterate the group of value;

foreach ($key in ${itemsValue.keySet()})
   if($itemsValue.get($key)==1)
        Condition
   end
end

In the above code we can see check the value will be like -"data1,data2 etc ..." but after using the get(), we can able to get the instance value.
