LinkedBlockingDeque的remainingCapacity()方法返回此雙端隊列在沒有阻塞的情況下理想情況下可以接受的其他元素的數量(在沒有內存或資源約束的情況下)。
remainingCapacity() = final_size() – current_size()
用法:
public int remainingCapacity()
參數:此方法不接受任何參數。
返回值:此方法返回可以插入雙端隊列容器的剩餘元素數。
以下示例程序旨在說明LinkedBlockingDeque的remainingCapacity()方法:
示例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());
}
}
輸出:
Linked Blocking Deque: [7855642, 35658786, 5278367, 74381793] remainingCapacity = : 2
示例2:
// 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());
}
}
輸出:
Linked Blocking Deque: [7855642, 35658786, 5278367, 74381793] remainingCapacity = 2
