voctor的一个用法(可以运行)

import java.util.Vector;
class Song
{
 public String s1=null;
 public String s2=null;
 public String s3=null;
 public String s4=null;
 public boolean b=false;
 public String s6=null;
 public String s7=null;

  public  Song(String s1,String s2,String s3,String s4,boolean b,String s6,String s7)
  {
   this.s1=s1;
   this.s2=s2;
   this.s3=s3;
   this.s4=s4;
   this.b=b;
   this.s6=s6;
   this.s7=s7;
  }
 
}
public class TestVector {  
 public static void main(String[] args){
 Vector v = new Vector();

 String s = new String("1");
 v.add(s);
 System.out.println(v.toString());
 String s0 = new String("12");
 v.add(s0);
 System.out.println(v.toString());
 Vector vector = new Vector();
 Song s1 = new Song("Pachchai Nirame", "2:15", "Tamil Pop", "Alai Payuthey (2000)",false, "TPS001", ";
 vector.add(s1);
 Song s2 = new Song("A Dios Le Pido", "1:50", "Latin Pop", "Juanes : Un Dia Normal/1", false, "SPS003", ";
 vector.add(s2);
 Song s3 = new Song("Bombay (Children of Combodia)", "2:38", "Jazz", "Fred Andersen Quartet/1", false, "WCS002", ";
 vector.add(s3);
 System.out.println(vector.toString());
 }
}

 

 

此段代码是在百度上见到的,我稍作修改,添加了一个类Song,结果反映出vector作为向量的存储.
