java.util.concurrent.ConcurrentSkipListSet.add()方法是Java中的内置函数,用于在此集合中插入元素。
用法:
ConcurrentSkipListSet.add(E e)
参数:该函数接受单个参数,即要插入的元素。
返回值:该函数返回True布尔值。
以下示例程序旨在说明ConcurrentSkipListSet.add()方法:
示例1:在集合中添加整数。
// Java program to demonstrate add()
// method of ConcurrentSkipListSet
import java.util.concurrent.*;
class ConcurrentSkipListSetAddExample1 {
public static void main(String[] args)
{
// Creating a set object
ConcurrentSkipListSet<Integer> Lset =
new ConcurrentSkipListSet<Integer>();
// Adding elements to this set
for (int i = 10; i <= 50; i += 10)
Lset.add(i);
// Printing elements of the set
System.out.println("The set contains: ");
for (Integer i : Lset)
System.out.print(i + " ");
}
}
输出:
The set contains: 10 20 30 40 50
示例2:在集合中添加字符串。
// Java program to demonstrate add()
// method of ConcurrentSkipListSet
import java.util.concurrent.*;
class ConcurrentSkipListSetAddExample2 {
public static void main(String[] args)
{
// Creating a set object
ConcurrentSkipListSet<String> Lset =
new ConcurrentSkipListSet<String>();
// Adding elements to this set
Lset.add("alex");
Lset.add("bob");
Lset.add("chuck");
Lset.add("drake");
Lset.add("eric");
// Printing elements of the set
System.out.println("The set contains: ");
for (String i : Lset)
System.out.print(i + " ");
}
}
输出:
The set contains: alex bob chuck drake eric
