# 如何在 java 中使用索引删除`Vector`元素 > 原文： [https://beginnersbook.com/2014/06/how-to-remove-vector-elements-using-index-in-java-example/](https://beginnersbook.com/2014/06/how-to-remove-vector-elements-using-index-in-java-example/) 在本教程中，我们将学习如何使用索引从[`Vector`](https://beginnersbook.com/2014/06/search-elements-in-vector-using-index-java-example/)中删除元素。我们将使用`Vector`类的[`remove(int index)`方法](https://docs.oracle.com/javase/7/docs/api/java/util/Vector.html#remove(int))。 `public E remove(int index)`：删除此`Vector`中指定位置的元素。将任何后续元素向左移位（从索引中减去一个）。返回从[`Vector`](https://beginnersbook.com/2013/12/vector-in-java/)中删除的元素。 #### 示例 索引从 0 开始，所以如果我们调用`remove(2)`，它将从`Vector`中删除第 3 个元素。 ```java 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)); } } } ``` **输出：** ```java Vector elements before remove(): C++ Java Cobol C Oracle Element removed from Vector is: Cobol Vector elements after remove(): C++ Java C Oracle ``` 这是从指定索引中删除`Vector`元素的示例。
