请教一个菜鸟问题，如何获得vct.toArray()?

[Ronanljy]

Vector v = new Vector();
v.add("111");
v.add("222");
String[] s = null;
s = (String[])v.toArray();

请问为什么会出现ClassCastException错误?

[jFresH_MaN]

String[] s = null;
v.copyInto(s);

[chanceqw]

Vector v=new Vector();
v.add("111");
v.add("222");
v.trimToSize();
String s[]=new String[v.capacity()];
for(int i=0;i<s.length;i++){
s[i]=(String) v.elementAt(i);
}

[shangqiao]

Vector v = new Vector();
v.add("111");
v.add("222");
String[] s = null;
s = (String[])v.toArray(new String[]{});
