Removing items from a list [duplicate]

Question

While looping through a list, I would like to remove an item of a list depending on a condition. See the code below.

This gives me a ConcurrentModification exception.

for (Object a : list) {     if (a.getXXX().equalsIgnoreCase("AAA")) {         logger.info("this is AAA........should be removed from the list ");         list.remove(a);     } } 

How can this be done?

Answer 1

for (Iterator<String> iter = list.listIterator(); iter.hasNext(); ) {     String a = iter.next();     if (...) {         iter.remove();     } } 

Making an additional assumption that the list is of strings. As already answered, an list.iterator() is needed. The listIterator can do a bit of navigation too.

Update

As @AyushiJain commented, there is

list.removeIf(...);
