Java 中 linkedblockingrequesize()方法
原文:https://www . geeksforgeeks . org/link edblockingeque-size-method-in-Java/
的 size() 方法链接了锁定请求返回当前的德格容器大小。在调用该函数时，将返回 Deque 容器中的元素数量。如果容器是容量受限的，那么它还返回在函数调用时容器中存在的元素的数量。
语法:
public int size()
返回:该方法返回一个整数值，表示容器中的元素数量。
下面的程序说明了 linkedblockingrequest 的 size()方法:
程序 1:
// Java Program to demonstrate public int size()
// method of LinkedBlockingDeque
import java.util.concurrent.LinkedBlockingDeque;
import java.util.*;
public class GFG {
public static void main(String[] args)
throws InterruptedException
{
// create object of LinkedBlockingDeque
LinkedBlockingDeque<Integer> LBD
= new LinkedBlockingDeque<Integer>();
// Add numbers to end of LinkedBlockingDeque
LBD.add(15);
LBD.add(20);
LBD.add(20);
LBD.add(15);
LBD.add(15);
LBD.add(20);
LBD.add(20);
LBD.add(15);
// print Dequeue
System.out.println("Linked Blocking Deque: " + LBD);
// prints the Deque after removal
System.out.println("Size of Linked Blocking Deque: "
+ LBD.size());
}
}
输出:
Linked Blocking Deque: [15, 20, 20, 15, 15, 20, 20, 15]
Size of Linked Blocking Deque: 8
程序二:
// Java Program to demonstrate public int size()
// method of LinkedBlockingDeque
import java.util.concurrent.LinkedBlockingDeque;
import java.util.*;
public class GFG {
public static void main(String[] args)
throws InterruptedException
{
// create object of LinkedBlockingDeque
LinkedBlockingDeque<String> LBD
= new LinkedBlockingDeque<String>();
// Add numbers to end of LinkedBlockingDeque
LBD.add("geeks");
LBD.add("forGeeks");
LBD.add("A Computer");
LBD.add("Portal");
// print Dequeue
System.out.println("Linked Blocking Deque: " + LBD);
// prints the Deque after removal
System.out.println("Size of Linked Blocking Deque: "
+ LBD.size());
}
}
输出:
Linked Blocking Deque: [geeks, forGeeks, A Computer, Portal]
Size of Linked Blocking Deque: 4
