Java 中 link edblockingrequest remainingCapacity()方法
原文:https://www . geeksforgeeks . org/linkedblockingreque-remainingcapacity-method-in-Java/
link edblockingequest的 remainingCapacity() 方法返回这个 deque 在没有阻塞的情况下(在没有内存或资源限制的情况下)可以理想地接受的附加元素的数量。
剩余空间()= final _ size()–current _ size()
语法:
public int remainingCapacity()
参数:该方法不接受任何参数。
返回:这个方法返回可以插入到 deque 容器中的剩余元素数。
下面的程序说明了 link edblockingrequest 的 remainingCapacity()方法:
程序 1:
// Java Program Demonstrate remainingCapacity()
// method of LinkedBlockingDeque
// when initial size is mentioned
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>(6);
// Add numbers to end of LinkedBlockingDeque
LBD.add(7855642);
LBD.add(35658786);
LBD.add(5278367);
LBD.add(74381793);
// print Dequeue
System.out.println("Linked Blocking Deque: " + LBD);
System.out.println("remainingCapacity = : " +
LBD.remainingCapacity());
}
}
输出:
Linked Blocking Deque: [7855642, 35658786, 5278367, 74381793]
remainingCapacity = : 2
程序二:
// Java Program Demonstrate remainingCapacity()
// method of LinkedBlockingDeque
// when no initial size is mentioned
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>(6);
// Add numbers to end of LinkedBlockingDeque
LBD.add(7855642);
LBD.add(35658786);
LBD.add(5278367);
LBD.add(74381793);
// print Dequeue
System.out.println("Linked Blocking Deque: " + LBD);
System.out.println("remainingCapacity = " +
LBD.remainingCapacity());
}
}
输出:
Linked Blocking Deque: [7855642, 35658786, 5278367, 74381793]
remainingCapacity = 2
