Java中的 AbstractSequentialList size() 方法与示例

Java中AbstractSequentialList的size()方法用于获取此 AbstractSequentialList 实例的大小。它返回一个整数值，该值是此 AbstractSequentialList 实例的大小。

句法：

public int size()

参数：此方法不接受任何参数。

返回：该方法返回一个整数值，该值是此 AbstractSequentialList 实例的大小。

下面的示例说明了 AbstractSequentialList.size() 方法：

示例 1：

// Java code to demonstrate the working of
// size() method in AbstractSequentialList
  
import java.util.*;
  
public class GFG {
    public static void main(String[] args)
    {
        // creating an AbstractSequentialList
        AbstractSequentialList arr
            = new LinkedList();
  
        // using add() to initialize values
        // [1, 2, 3, 4]
        arr.add(1);
        arr.add(2);
        arr.add(3);
        arr.add(4);
  
        // print AbstractSequentialList
        System.out.println("AbstractSequentialList: "
                           + arr);
  
        // Get the size
        // using size()
        System.out.println("Size: "
                           + arr.size());
    }
}

输出：

AbstractSequentialList: [1, 2, 3, 4]
Size: 4

示例 2：

// Java code to demonstrate the working of
// size() method in AbstractSequentialList
  
import java.util.*;
  
public class GFG {
    public static void main(String[] args)
    {
        // creating an AbstractSequentialList
        AbstractSequentialList arr
            = new LinkedList();
  
        // using add() to initialize values
        // [Geeks, For, ForGeeks, GeeksForGeeks]
        arr.add("Geeks");
        arr.add("For");
        arr.add("ForGeeks");
        arr.add("GeeksForGeeks");
  
        // print AbstractSequentialList
        System.out.println("AbstractSequentialList: "
                           + arr);
  
        // Get the size
        // using size()
        System.out.println("Size: "
                           + arr.size());
    }
}

输出：

AbstractSequentialList: [Geeks, For, ForGeeks, GeeksForGeeks]
Size: 4
