Given a list of elements, I want to get the element with a given property and remove it from the list. The best solution I found is:

Answer 1

With Eclipse Collections you can use detectIndex along with remove(int) on any java.util.List.

List integers = Lists.mutable.with(1, 2, 3, 4, 5);
int index = Iterate.detectIndex(integers, i -> i > 2);
if (index > -1) {
    integers.remove(index);
}

Assert.assertEquals(Lists.mutable.with(1, 2, 4, 5), integers);

If you use the MutableList type from Eclipse Collections, you can call the detectIndex method directly on the list.

MutableList integers = Lists.mutable.with(1, 2, 3, 4, 5);
int index = integers.detectIndex(i -> i > 2);
if (index > -1) {
    integers.remove(index);
}

Assert.assertEquals(Lists.mutable.with(1, 2, 4, 5), integers);
