Java LinkedList listIterator() 方法

示例

使用 ListIterator 在列表中向前和向后循环

import java.util.LinkedList;
import java.util.ListIterator;

public class Main {
  public static void main(String[] args) {
  
    // Make a collection
    LinkedList<String> cars = new LinkedList<String>();
    cars.add("Volvo");
    cars.add("BMW");
    cars.add("Ford");
    cars.add("Mazda");
  
    // Get the iterator
    ListIterator<String> it = cars.listIterator();
    
    // Loop through the list
    while(it.hasNext()) {
      System.out.println(it.next());
    }
    
    System.out.println("---");
    
    // Loop backwards through the list
    while(it.hasPrevious()) {
      System.out.println(it.previous());
    }
  }
}
