程序如下：
package MyPack;
class Balance {
String name;
double bal;
Balance(String n,double b) {
name=n;
bal=b;
}
void show() {
if(bal");
System.out.println(name+":$"+bal);
}
}
class AccountBalance {
public static void main(String args[])
{
Balance current[] = new Balance[3];
Balance[0] = new Balance("K.Yan",123.23);
Balance[1] = new Balance("C.Zhang",157.02);
Balance[2] = new Balance("W.Tom",-12.33);
for(int i=0;i");
System.out.println(name+":$"+bal);
}
}
class AccountBalance {
public static void main(String args[])
{
Balance current[] = new Balance[3];
current[0] = new Balance("K.Yan",123.23);
current[1] = new Balance("C.Zhang",157.02);
current[2] = new Balance("W.Tom",-12.33);
for(int i=0;i<=2;i++)
current.show();
}
}
不知道是你要的不?
