loop on list with remove [duplicate]

Question

    for (String fruit : list)     {         if("banane".equals(fruit))             list.remove(fruit);         System.out.println(fruit);     } 

Here a loop with remove instruction. At execution time, I get some ConcurrentModificationException, below the console output:

Exception in thread "main" java.util.ConcurrentModificationException at java.util.AbstractList$Itr.checkForComodification(AbstractList.java:449) at java.util.AbstractList$Itr.next(AbstractList.java:420) at Boucle.main(Boucle.java:14) abricot banane 

Question: How to remove some element with a loop?

Answer 1

You need to use the iterator directly, and remove the item via that iterator.

for (Iterator<String> iterator = list.iterator(); iterator.hasNext(); ) {     String fruit = iterator.next();     if ("banane".equals(fruit)) {         iterator.remove();     }     System.out.println(fruit); }
