How to traverse an array using a Java iterator?

You can use a Java iterator to traverse an array, the specific steps are as follows:

1. Create an array object, which can be either an array of primitive data types or an array of objects.
2. Convert the array object to a collection object using the asList() method of the Arrays class.
3. Obtain an iterator object using the iterator() method of a collection object.
4. Traverse the array using a while loop and the hasNext() and next() methods of an iterator.

Here is an example code:

import java.util.Arrays;
import java.util.Iterator;
import java.util.List;

public class Main {
    public static void main(String[] args) {
        // 创建数组对象
        Integer[] array = {1, 2, 3, 4, 5};
        
        // 将数组对象转换为集合对象
        List<Integer> list = Arrays.asList(array);
        
        // 使用集合对象的iterator()方法获取迭代器对象
        Iterator<Integer> iterator = list.iterator();
        
        // 使用while循环和迭代器的hasNext()和next()方法遍历数组
        while (iterator.hasNext()) {
            Integer element = iterator.next();
            System.out.println(element);
        }
    }
}

Running the code above will result in:
