Java 中的 copy onwriterarrayset spliterator()方法
原文:https://www . geeksforgeeks . org/copy onwriterarrayset-spliterator-method-in-Java/
copy onwriterarrayset的拆分器()方法按正确的顺序返回该集合中元素的拆分器。在拆分器上操作时不需要同步。
语法:
public Spliterator spliterator()
返回值:该函数在集合中的元素上返回一个分割器。
以下程序说明了上述功能:
程序 1:
// Java Program to illustrate the CopyOnWriteArraySet
// spliterator() method in Java
import java.util.concurrent.CopyOnWriteArraySet;
import java.util.*;
public class GFG {
public static void main(String[] args)
{
// create object of CopyOnWriteArraySet
CopyOnWriteArraySet<Integer> ArrSet
= new CopyOnWriteArraySet<Integer>();
// Add elements
ArrSet.add(32);
ArrSet.add(67);
ArrSet.add(67);
ArrSet.add(100);
// print CopyOnWriteArraySet
System.out.println("CopyOnWriteArraySet: "
+ ArrSet);
Spliterator<Integer>
numbers = ArrSet.spliterator();
// print result from Spliterator
System.out.println("Set of Numbers:");
// forEachRemaining method of Spliterator
numbers
.forEachRemaining(
(n) -> System.out.println(n));
}
}
输出:
CopyOnWriteArraySet: [32, 67, 100]
Set of Numbers:
32
67
100
程序二:
// Java Program to illustrate the CopyOnWriteArraySet
// spliterator() method in Java
import java.util.concurrent.CopyOnWriteArraySet;
import java.util.*;
public class GFG {
public static void main(String[] args)
{
// create object of CopyOnWriteArraySet
CopyOnWriteArraySet<String> ArrSet
= new CopyOnWriteArraySet<String>();
// Add elements
ArrSet.add("gopal");
ArrSet.add("gfg");
ArrSet.add("jgec");
ArrSet.add("sudo");
// print CopyOnWriteArraySet
System.out.println("CopyOnWriteArraySet: "
+ ArrSet);
Spliterator<String>
numbers = ArrSet.spliterator();
// print result from Spliterator
System.out.println("Set of strings:");
// forEachRemaining method of Spliterator
numbers
.forEachRemaining(
(n) -> System.out.println(n));
}
}
输出:
CopyOnWriteArraySet: [gopal, gfg, jgec, sudo]
Set of strings:
gopal
gfg
jgec
sudo
