Hey. So I have written this:
public class BakeSale {

public static void main(String args) {

int numCookies = 17;

int numCupcakes = 12;

// Now cookies are being sold. First I sell 3, then I sell half. 

int numCookies -= 3;

int numCookies /= 2;

// Let's see how many is left'




This produce errors:
BakeSale.java:6: error: ‘;’ expected
int numCookies -= 3;
BakeSale.java:7: error: ‘;’ expected
int numCookies /= 2;
2 errors

I think I’ve written everything just like the assignment explains. I even passed the assignment and can continue.

Why are there errors?

Welcome to the forums!

Once we declare the data type of a variable, we don’t need to do it again. Because you already indicated that numCookies and numCupcakes are ints, you should not do it again when you are manipulating them. What change do you need to make?

I am getting the same error message but I don’t want to change anything I would like to see the output.
