发帖数: 26 | 1 I use JBuilder8
I wanna declare a array of vector, so i use:
Vector[] tables = new Vector[20];
It seems okay now. But when i try to use like
tables[1]
JBuilder will send error information.
What's wrong? I am not good at java.
Thanks. | g*****g

is. Probably because you didn't create Vector though.
for(i=0; i<20; i++){
tables[i] = new Vector();
}
