}
public class b
{
public static void main(String args[ ])
{
Win win=new Win();
win.judge(30);
win.input("邬志刚","男","1985年11月2日","04级","软件学院","5","班长","体育部",
"部长","呼兰","123");
win.input("w王慧玲","女","1985年11月2日","04级","软件学院","5","班长","女生部",
"部长","呼兰","123");
win.input("邬志刚","女男","1985年11月2日","04级","软件学院","5","班长","体育部",
"部长","呼兰","123");
win.output();
}
}
我存到a数组里是3种数据,为什么输出的时候前2个却是空的,只有第3个存入了
是使用Object的问题吗?
应如何改正.
如果用Vecter可以做吗?

是vector吧？当然可以，但是你最好翻翻书看看，有比vector更合适东西。你这个明显是字符串数组阿，为啥用object？不管怎么样，不用向量肯定不行的
