Java AbstractSequentialList |迭代器()方法

Java中的AbstractSequentialList iterator()方法用于获取列表上的迭代器或列表迭代器。它返回此列表中元素的迭代器(以正确的顺序)。此方法覆盖类 AbstractList 中的 iterator()

句法:

public Iterator iterator()

返回值:此方法返回此列表中元素的迭代器(以正确的顺序)。

下面是说明 iterator() 方法的代码:

方案一:

// Java program to demonstrate
// iterator() method
  
import java.util.*;
  
public class GfG {
  
    public static void main(String[] args)
    {
        // Creating an instance of the AbstractSequentialList
        AbstractSequentialList absl = new LinkedList<>();
  
        // adding elements to absl
        absl.add(5);
        absl.add(6);
        absl.add(7);
        absl.add(2, 8);
        absl.add(2, 7);
        absl.add(1, 9);
        absl.add(4, 10);
  
        // Getting Iterator
        Iterator Itr = absl.iterator();
  
        // Traversing elements with help of iterator
        while (Itr.hasNext()) {
            System.out.print(Itr.next() + " ");
        }
    }
}
输出:
5 9 6 7 10 8 7

方案二:

// Java program to demonstrate
// iterator() method
  
import java.util.*;
  
public class GfG {
  
    public static void main(String[] args)
    {
        // Creating an instance of the AbstractSequentialList
        AbstractSequentialList absl = new LinkedList<>();
  
        // adding elements to absl
        absl.add("Geeks");
        absl.add("ForGeeks");
        absl.add("A");
        absl.add("Portal");
        absl.add(3, "Computer Science");
        absl.add(5, "For Geeks");
  
        // Getting Iterator
        Iterator Itr = absl.iterator();
  
        // Traversing elements with help of iterator
        while (Itr.hasNext()) {
            System.out.println(Itr.next());
        }
    }
}
输出:
Geeks
ForGeeks
A
Computer Science
Portal
For Geeks
