Help with anonymous class

Question

The following code compiles correctly and passed the test, but there's no output. How can it pass if output is expected?

public class Main
{
public static void main(String[] args) {

Purchase customer = new Purchase();
Purchase specialCustomer = new Purchase(){
//your code goes here
int price;

public int totalAmount(int price) {
return price - (price*20)/100;
}
};

System.out.println(customer.totalAmount(1000));
System.out.println(specialCustomer.totalAmount(100000));
}
}

class Purchase {
int price;

public int totalAmount(int price) {
return price - (price*10)/100;
}
}

Answer 1

Ok good job 👍

Answer 2

I don't see the need for <price> member in either the regular or anonym class here.

You can try to remove (or comment) their declarations in the code and it may work.

Answer 3

You're welcome,
But that's kinda odd, I removed both `int price;` declarations and code still works okay. Idk why you got that timeout , cause I don't experience that.

Answer 4

Thanks, I take out variable in anonymous and it works as it should. Taking out the other one cause time out.

Answer 5

Must have been a network connection thing, after running again it works both ways. Thanks for the help. Took me while to figure out there was an extra "}" in one area of the original code.

Answer 6

You are a store manager.
You are offering a 10% discount on all items in the store. Today, you have had a total of two customers. To the first, you honored the 10% discount on all purchased items. The second customer, however, purchased a lot of items and you want to give him a bigger discount -- 20% -- to show your appreciation.
Complete the program by creating two Purchase objects - 1 for the regular customer, and 1 for a special one, and override the totalAmount() method for the special customer on the fly to set the proper 20% discount.
