Java AbstractSequentialList addAll()用法及代碼示例

AbstractSequentialList的addAll(int index，Collection C)方法用於將作為參數傳遞給此函數的集合中的所有元素附加到此函數的抽象順序列表的特定索引或位置。

用法:

boolean addAll(int index, Collection C)

參數：此函數接受上麵語法中所示的兩個參數，並在下麵進行描述。

index：此參數為整數數據類型，並指定列表中從容器元素插入位置開始的位置。
C：這是一個集合，其元素需要附加。

返回值：如果至少執行了一個附加動作，則該方法返回TRUE。

以下示例程序旨在說明Java.util.AbstractSequentialList.addAll()方法：

範例1：

// Java code to illustrate addAll() method 
  
import java.util.*; 
import java.util.AbstractSequentialList; 
  
public class AbstractSequentialListDemo { 
    public static void main(String args[]) 
    { 
  
        // Creating an empty AbstractSequentialList 
        AbstractSequentialList<String> 
            absqlist = new LinkedList<String>(); 
  
        // Use add() method to add elements 
        absqlist.add("Geeks"); 
        absqlist.add("for"); 
        absqlist.add("Geeks"); 
        absqlist.add("10"); 
        absqlist.add("20"); 
  
        // Creating a Collection 
        Collection<String> 
            collect = new ArrayList<String>(); 
        collect.add("A"); 
        collect.add("Computer"); 
        collect.add("Portal"); 
        collect.add("for"); 
        collect.add("Geeks"); 
  
        // Displaying the list 
        System.out.println("AbstractSequentialList:"
                           + absqlist); 
  
        // Appending the collection to the list 
        absqlist.addAll(1, collect); 
  
        // Clearing the list using clear() and displaying 
        System.out.println("The new list is:"
                           + absqlist); 
    } 
}

輸出：

AbstractSequentialList:[Geeks, for, Geeks, 10, 20]
The new list is:[Geeks, A, Computer, Portal, for, Geeks, for, Geeks, 10, 20]

範例2：

// Java code to illustrate boolean addAll() 
  
import java.util.*; 
import java.util.AbstractSequentialList; 
  
public class AbstractSequentialListDemo { 
    public static void main(String args[]) 
    { 
  
        // Creating an empty AbstractSequentialList 
        AbstractSequentialList<Integer> 
            absqlist = new LinkedList<Integer>(); 
  
        // Use add() method to add elements 
        absqlist.add(10); 
        absqlist.add(20); 
        absqlist.add(30); 
        absqlist.add(10); 
        absqlist.add(20); 
  
        // Creating a Collection 
        Collection<Integer> 
            collect = new LinkedList<Integer>(); 
        collect.add(1); 
        collect.add(2); 
        collect.add(3); 
        collect.add(4); 
        collect.add(5); 
  
        // Displaying the list 
        System.out.println("The AbstractSequentialList is:"
                           + absqlist); 
  
        // Appending the collection to the list 
        absqlist.addAll(1, collect); 
  
        // Clearing the list using clear() and displaying 
        System.out.println("The new list is:" + absqlist); 
    } 
}

輸出：

The AbstractSequentialList is:[10, 20, 30, 10, 20]
The new list is:[10, 1, 2, 3, 4, 5, 20, 30, 10, 20]
