I need help with my code. When I run it, I only get one error.

This is the only error I get

Calculator.java:36: error: reached end of file while parsing

Here is my code below. Help me find my mistake:

```
// July 9 2020
public class calculator {
public calculator(){
}
public int add (int a, int b) {
add = a + b;
return add;
}
public int subtract (int a, int b) {
subtract = a - b;
return subtract;
}
public int multiply (int a, int b) {
multiply = a * b;
return multiply;
}
public int divide (int a, int b) {
divide = a / b;
return divide;
}
public int modulo (int a, int b) {
modulo = a % b;
return modulo;
}
public static void main(String[] args) {
calculator myCalculator = new calculator();
System.out.println(myCalculator.add(4,7));
System.out.println(myCalulator.subtract(45,11));
}
```
