Implement a CompositeIterator using generics that combines two iterators of the same type.

Below is an example implementation of CompositeIterator in Java using generics, which combines two iterators of the same type T:

import java.util.Iterator;
import java.util.NoSuchElementException;

public class CompositeIterator<T> implements Iterator<T> {
    private final Iterator<T> first;
    private final Iterator<T> second;

    public CompositeIterator(Iterator<T> first, Iterator<T> second) {
        this.first = first;
        this.second = second;
    }

    @Override
    public boolean hasNext() {
        return first.hasNext() || second.hasNext();
    }

    @Override
    public T next() {
        if (first.hasNext()) {
            return first.next();
        } else if (second.hasNext()) {
            return second.next();
        } else {
            throw new NoSuchElementException();
        }
    }

    @Override
    public void remove() {
        throw new UnsupportedOperationException("Remove not supported");
    }
}

This iterator first iterates over elements from the first iterator, then from the second, combining them into a single stream of elements.
