java vector 使用示例，javavector,package cn.o

package cn.outofmemory.snippets.core;import java.util.Vector;public class ClearVectorExample {  public static void main(String[] args) {    // Create a Vector and populate it with elements    Vector vector = new Vector();    vector.add("element_1");    vector.add("element_2");    vector.add("element_3");    System.out.println("Vector size before removing elements : " + vector.size());    // Vector clear() operation removes all elements    vector.clear();    System.out.println("Vector size after removing elements : " + vector.size());  }}

输出：

Vector size before removing elements : 3Vector size after removing elements : 0
