Java LinkedBlockingDeque addAll()用法及代碼示例

LinkedBlockingDeque的addAll()方法將指定集合的所有元素附加到此雙端隊列的末尾。

用法:

public void addAll(Collection<E> c)

參數：此方法接受強製參數c，該參數是要在LinkedBlockingDeque末尾插入的集合。

返回值：此方法不返回任何內容。

異常：存在2個異常：

IllegalStateException：如果由於容量限製此時無法添加集合。
NullPointerException ：如果指定的集合為Null。

以下示例程序旨在說明LinkedBlockingDeque類的addAll()函數：

範例1：

// Java Program Demonstrate addAll() 
// method of LinkedBlockingDeque 
  
import java.util.concurrent.LinkedBlockingDeque; 
import java.util.*; 
  
public class GFG { 
    public static void main(String[] args) 
        throws IllegalStateException 
    { 
  
        // Create object of LinkedBlockingDeque 
        LinkedBlockingDeque<Integer> LBD 
            = new LinkedBlockingDeque<Integer>(); 
  
        // Add numbers to end of LinkedBlockingDeque 
        LBD.add(11); 
        LBD.add(22); 
        LBD.add(33); 
        LBD.add(44); 
  
        // Print deque 
        System.out.println("Linked Blocking Deque: "
                           + LBD); 
  
        // Create object of ArrayList collection 
        ArrayList<Integer> ArrLis 
            = new ArrayList<Integer>(); 
  
        // Add number to ArrayList 
        ArrLis.add(55); 
        ArrLis.add(66); 
        ArrLis.add(77); 
        ArrLis.add(88); 
  
        // Print ArrayList 
        System.out.println("ArraList: "
                           + ArrLis); 
  
        // Function addAll() adds all the elements of 
        // ArrayList to Deque 
        LBD.addAll(ArrLis); 
  
        // Print deque 
        System.out.println("Linked Blocking Deque: "
                           + LBD); 
    } 
}

範例2：

// Java Program Demonstrate addAll() 
// method of LinkedBlockingDeque 
  
import java.util.concurrent.LinkedBlockingDeque; 
import java.util.*; 
  
public class GFG { 
    public static void main(String[] args) 
        throws IllegalStateException 
    { 
  
        // Create object of LinkedBlockingDeque 
        LinkedBlockingDeque<String> LBD 
            = new LinkedBlockingDeque<String>(); 
  
        // Add elements to end of LinkedBlockingDeque 
        LBD.add("GeeksforGeeks"); 
        LBD.add("Gfg"); 
        LBD.add("Geeks"); 
  
        // Print deque 
        System.out.println("Linked Blocking Deque: "
                           + LBD); 
  
        // Create object of ArrayList collection 
        ArrayList<String> ArrLis 
            = new ArrayList<String>(); 
  
        // Add elements to ArrayList 
        ArrLis.add("Computer"); 
        ArrLis.add("Science"); 
        ArrLis.add("Portal"); 
  
        // Print ArrayList 
        System.out.println("ArraList: " + ArrLis); 
  
        // Function addAll() adds all the elements of 
        // ArrayList to Deque 
        LBD.addAll(ArrLis); 
  
        // Print deque 
        System.out.println("Linked Blocking Deque: "
                           + LBD); 
    } 
}
