Java 集合 使用索引删除Vector元素

import java.util.Vector;
public class RemoveExample {
 public static void main(String[] args) {

    // Creating a Vector of Strings
    Vector<String> vector = new Vector<String>();

    //Adding elements to the Vector
    vector.add("C++");
    vector.add("Java");
    vector.add("Cobol");
    vector.add("C");
    vector.add("Oracle");

    System.out.println("Vector elements before remove(): ");
    for(int i=0; i < vector.size(); i++)
    {
       System.out.println(vector.get(i));
    }

    // Removing 3rd element from Vector
    Object obj = vector.remove(2);

    System.out.println("\nElement removed from Vector is:");
    System.out.println(obj);

    System.out.println("\nVector elements after remove():");
    for(int i=0; i < vector.size(); i++)
    {
       System.out.println(vector.get(i));
    }
 }
}

Vector elements before remove(): 
C++
Java
Cobol
C
Oracle

Element removed from Vector is:

Vector elements after remove():
C++
Java
C
Oracle
