Count the occurrences of items in ArrayList

Question

I have a java.util.ArrayList and an Item object.

Now, I want to obtain the number of times the Item is stored in t

Answer 1

Thanks for your all nice suggestion. But this below code is really very useful as we dont have any search method with List that can give number of occurance.

void insert(Item newEl) 
{ 
   if (counters.contains(newEl)) 
     counters.put(newEl, counters.get(newEl)+1); 
   else 
     counters.put(newEl, 1); 

   items.add(newEl); 
 } 

Thanks to Jack. Good posting.
