2025 年 3 月 22 日 | 阅读需 2 分钟

ListIterator 接口的 nextIndex() 方法用于返回 next() 方法将要返回的元素的索引。

语法

参数

不适用

上述方法用于返回 next() 方法将要返回的元素的索引。如果列表迭代器位于列表的末尾，该方法也可能返回列表的大小。

示例 1

import java.util.ArrayList;
import java.util.ListIterator;
public class JavaListIteratornextIndexExample1 {
	public static void main(String[] args) {
	 ArrayList < String > vehicles = new ArrayList < String > (); 
	 vehicles.add("Scooter");
	 vehicles.add("Car");
	 vehicles.add("Truck");
	 vehicles.add("Bike");
	 System.out.println("The vehicles are listed as :"+vehicles);
     ListIterator < String > listIterator = vehicles.listIterator();
     System.out.println("The first Index is given as : " + listIterator.nextIndex());
       listIterator.next();
     System.out.println("The second Index is given as : " + listIterator.nextIndex());
       listIterator.next();
     System.out.println("The third index is given as : " + listIterator.nextIndex());
     listIterator.next();
     System.out.println("The fourth index is given as : " + listIterator.nextIndex());
    }
}

输出

The vehicles are listed as :[Scooter, Car, Truck, Bike]
The first Index is given as : 0
The second Index is given as : 1
The third index is given as : 2
The fourth index is given as : 3

示例 2

import java.util.ArrayList;
import java.util.ListIterator;
public class JavaListIteratornextIndexExample2 {
   public static void main(String[] args) {
	   ArrayList < Float > marks = new ArrayList < Float > (); 
	   marks.add(22.4f);
	   marks.add(34.98f);
	   marks.add(12.9f);
	   marks.add(76.4f);
		 System.out.println("The marks are listed as : "+ marks);
	     ListIterator < Float > listIterator = marks.listIterator();
System.out.println("The first Index is given as : " + listIterator.nextIndex());
	       listIterator.next();
System.out.println("The second Index is given as : " + listIterator.nextIndex());
	       listIterator.next();
System.out.println("The third index is given as : " + listIterator.nextIndex());
	     listIterator.next();
System.out.println("The fourth index is given as : " + listIterator.nextIndex());
	    }
	}

输出

The marks are listed as : [22.4, 34.98, 12.9, 76.4]
The first Index is given as : 0
The second Index is given as : 1
The third index is given as : 2
The fourth index is given as : 3

示例 3

import java.util.ArrayList;
import java.util.ListIterator;
public class JavaListIteratornextIndexExample3 {
    public static void main(String[] args) {
    	 ArrayList < Integer > marks= new ArrayList < Integer > (); 
    	 marks.add(5);
    	 marks.add(10);
    	 marks.add(15);
    	 marks.add(20);
    	 System.out.println("The ages are listed as :"+marks);
         ListIterator < Integer > listIterator = marks.listIterator();
         System.out.println("The first Index is given as : " + listIterator.nextIndex());
           listIterator.next();
         System.out.println("The second Index is given as : " + listIterator.nextIndex());
           listIterator.next();
         System.out.println("The third index is given as : " + listIterator.nextIndex());
         listIterator.next();
         System.out.println("The fourth index is given as : " + listIterator.nextIndex());
        }
    }

输出

The ages are listed as :[5, 10, 15, 20]
The first Index is given as : 0
The second Index is given as : 1
The third index is given as : 2
The fourth index is given as : 3
