how to search in a list in java?

Question

i have three list containing 3/4 items in each. Now a node contains each those items. when the node is assigned to a particular item it has to search for that item in those list and should return the particular list containing that item. How can i do this?

Answer 1

Try this : In case the

if(listOne.contains(object))
            return listOne;

The list.contains() uses equals. so, if list.contains() does not give you the expected result, you should be overriding the equals method.
