怎么取出存放在Vector列表中 的对象中的各个属性？

将map里的键值对作为vector的一个元素 然后根据这个排序 自然key就好了

import java.util.Vector;

public class Test {

public static void main(String[] args) {
Vector ve = new Vector();
InfoVO info = new InfoVO();
for (int i = 0; i < 2; i++) {
info.setName("aaa");
info.setNumber("110");
ve.add(info);
}

for(int j = 0; j < ve.size(); j++){
System.out.println("Vector element " + (j + 1) + " details: ");
InfoVO inf = (InfoVO) ve.get(j);
System.out.println("Inf name: " + inf.getName());
System.out.println("Inf number: " + inf.getNumber());

}

}

}

class InfoVO{
String name;
String number;
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getNumber() {
return number;
}
public void setNumber(String number) {
this.number = number;
}

}
