Java TreeSet Spliterator()用法及代码示例

public Spliterator<E> spliterator()

import java.util.*;
public class JavaTreeSetSpilteratorExample1
{
  public static void main(String as[]){
  TreeSet <Integer>obj = new TreeSet<Integer>();
 
  obj.add(4);	
  obj.add(6);
  obj.add(9);
  obj.add(12);
  obj.add(18);
  System.out.println("TreeSet:" +obj);
  Spliterator<Integer> obj1 = obj.spliterator();
   System.out.println("Elements of TreeSet after using spliterator() method:");
  obj1.forEachRemaining(System.out::println);	
  }
}

TreeSet:[4, 6, 9, 12, 18]
