Explain what each line does and determine what will be the output for the println:
Collection<Integer> numbers = new LinkedList<>();
Output
numbers.add (1);
numbers.add (9);
numbers.add (10);
numbers.add (12);
numbers.add (14);
numbers.add (16) ;
numbers.add (18);
println(numbers);
println(numbers.size());
println(numbers. contains (8));
println(numbers. contains (12));
Iterator<Integer> iterator = numbers. iterator;
while(iterator hasNext) {
}
int value = iterator.next;
if (value>10) {
iterator.remove();
}
