Hashmap Iterator Remove Concurrentmodificationexception. Code to understand above concept: It is a solution or fix for concurrentmodificationexception for the java list. Alternatively, the collection.removeif() method introduced in java 8 can be used to remove an element from a collection if a given condition is true. We can use the remove() method of iterator to remove the object from the underlying collection object. The above exception can also be resolved by using an iterator to traverse the elements of the arraylist and using the iterator.remove() method to remove elements. This will throw a concurrentmodificationexception when the it.hasnext() is called the second time. Use the iterator.remove() method to remove the current entry, or use the map.entry.setvalue() method to modify the current entry's value. One method is to make use of java’s iterator interface and its add() and remove() methods to safely modify a collection during iteration. Use the iterator’s add() and/or remove() methods. We can also avoid the concurrent modification exception in a single threaded environment. Here two ways are proposed of which starting with the naive one and ending up with the optimal approach to reach the goal. You can use the remove() method from. But in this case, you can remove only the same object and not any other object from the list.
