Van(String driver, int rate) {
this.driver-driver; this.rate-rate;
}
public String toString() {return(driver+","+rate);}
class SpecVan extends Van { {
int type:
SpecVan() {}SpecVan(String driver, int rate, int type) {
super(driver, rate);
this.type=type;
}
void display() {
String s = "("+super.toString()+","+type+") ";System.out.println(s);
}
public class Main {
public static void main(String[] args) {
SpecVan x = new SpecVan();SpecVan y = new SpecVan ("Hoa",20,10);
x.display(); y.display();System.out.println();
}
