Using ListIterator class Using removeAll() method Using Java 8 Stream to filter List items Conclusion Introduction In this tutorial, you will learn how to remove element from Arraylist in java while iterating using different implementations provided by Java. It is necessary to understand the right ...

try{ selfie.delete(); }catch(NullPointerException unimportant) { } Common Mistake #8: Concurrent Modification Exception This exception occurs when a collection is modified while iterating over it using methods other than those provided by the iterator object. For example, we have a list of hats...

To add an element to the innerMapof the nestedHashMap, we first have to retrieve it. We can retrieve the inner object using theget()method. Then we can use theput()method on the innerMapobject and insert the new values: assertEquals(actualBakedGoodsMap.get("Cake").size(), 5); ...
List insertion speed is critically dependent on the size of the collection and the position where the element is to be inserted. For small collections ArrayList and LinkedList are close in performance, though ArrayList is generally the faster of the two. Precise speed comparisons depend on the JVM...
We have seen that a ConcurrentModificationException will be thrown if we try to modify a list while iterating over it. The solution is to use the iterator’s own remove method, which removes the last element returned by the iterator. 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17...
