代碼：
package test;
class D200_Card{
long card_num;
double balance;
D200_Card(long n,double b){
card_num=n;
balance=b;
}
}
class array10{
public static void main(String args[]){
int[] x;
D200_Card dc[],d1;
x=new int[3];
dc=new D200_Card [2];
System.out.println("x="+x+" dc="+dc);
System.out.println("----?---");
System.out.println("x="+x[0]);
System.out.println("dc[1]"+dc[1]);
x[0]=20;
d1=new D200_Card(280001,50.0);
dc[0]=new D200_Card(280001,50.0);
dc[1]=new D200_Card(280002,40.0);
System.out.println("-------");
System.out.println("x="+x[0]);
System.out.println("dc[1]"+dc[1]);
System.out.println(d1);
}
}
這個陣列的資料讀取不出來這是為什么
