Java 中的 ConcurrentSkipListSet 迭代器()方法
原文:https://www . geeksforgeeks . org/concurrentskiplistset-iterator-method-in-Java/
java . util . concurrentSkiplistset的迭代器()方法是 Java 中的内置函数，用于以升序返回该集合中元素的迭代器。 语法:
ConcurrentSkipListSet.iterator()
返回值:函数以升序返回该集合中元素的迭代器。
下面的程序说明了 Java . util . concurrentskiplistset . iterator(): 程序 1:
// Java Program Demonstrate iterator()
// method of ConcurrentSkipListSet
import java.util.Iterator;
import java.util.concurrent.ConcurrentSkipListSet;
class ConcurrentSkipListSetIteratorExample1 {
public static void main(String[] args)
{
// Initializing the set
ConcurrentSkipListSet<String>
set = new ConcurrentSkipListSet<String>();
// Adding elements to this set
set.add("Gfg");
set.add("is");
set.add("fun!!");
// Returns an iterator over the elements
Iterator<String> iterator = set.iterator();
// Printing the elements of the set
while (iterator.hasNext())
System.out.print(iterator.next() + " ");
}
}
Output:
Gfg fun!! is
