Remove all occurrences of an element from ArrayList

Question

I am using java.util.ArrayList, I want to remove all the occurrences of a particular element.

    List l = new ArrayList         


        

Answer 1

You can use the removeAll() method.

list.removeAll(Arrays.asList("someDuplicateString"));

Answer 2

Another way using Java 8:

l.removeIf("first"::equals);

Answer 3

l.removeAll(Collections.singleton("first"));

Answer 4

while(l.remove("first")) { }

This removes all elements "first" from the list.

Answer 5

Since in your example you are using Strings I guess did should do the trick.

for(int i = 0; i < list.size();i++){
    if(list.get(i).equals(someStringNameOrValue)){
        list.remove(i--);
    }
}

Looks like I misunderstood your question. I updated my answer. Am I right? you want to remove all occurrences of "first" ?
