Jump Iterator

Implements an iterator in each output it print the number and skip the next one.

Partial Code

public class JumpIterator implements Iterator<Integer> {
    public static void main(String[] args) {
        List<Integer> list = new ArrayList<Integer>();
        list.add(1); list.add(4);
        list.add(3); list.add(5);
        list.add(6); list.add(7);
        list.add(2);
        JumpIterator it = new JumpIterator(list.listIterator());
        while(it.hasNext()){
            System.out.println(it.next());
        }
    }
}

Output

1
3
6

Solution

public class JumpIterator implements Iterator<Integer> {

    Iterator<Integer> iterator;

    public JumpIterator(Iterator<Integer> iterator) {
        this.iterator = iterator;
    }

    @Override
    public boolean hasNext() {
        return iterator.hasNext();
    }

    @Override
    public Integer next() {
        int res = iterator.next();
        if (iterator.hasNext())
            iterator.next();
        return res;
    }

    public static void main(String[] args) {
        List<Integer> list = new ArrayList<Integer>();
        list.add(1); list.add(4);
        list.add(3); list.add(5);
        list.add(6); list.add(7);
        list.add(2);
        JumpIterator it = new JumpIterator(list.listIterator());
        while(it.hasNext()){
            System.out.println(it.next());
        }
    }
}
