几个简单的java学习代码

import java.util.*;

public class VectorApp {
  public static void main(String[] args) {
    Vector v = new Vector();
    for(int i = 0; i < 7; i++)
      v.addElement("vector"+i);

    v.insertElementAt("aa",0);

    Enumeration e = v.elements();

    while(e.hasMoreElements())
      System.out.print(e.nextElement()+" ");
    System.out.println();

    v.removeElement("vector1" );

    for(int i = 0; i < v.size() ; i++)
      System.out.print(v.elementAt(i) +" ");
    System.out.println();
  }
}


运行结果：

aa vector0 vector1 vector2 vector3 vector4 vector5 vector6 
aa vector0 vector2 vector3 vector4 vector5 vector6
