NOTE: in mathematics, division by zero is undefined. So, in Java, division by zero is always an error. Given an int variable named callsReceived and another int variable named operatorsOnCall, write the necessary code to read values into callsReceived and operatorsOnCall, and print out the number of calls received per operator (integer division with truncation will do). However: if any value read in is not valid input, just print the message "INVALID".

### Division by Zero in Java

#### Division by Zero and Java
In mathematics, division by zero is undefined. Consequently, in Java, division by zero is always an error.

#### Exercise:
Given the context of an `int` variable named `callsReceived` and another `int` variable named `operatorsOnCall`, write the necessary code to:
1. Read values into `callsReceived` and `operatorsOnCall`.
2. Print out the number of calls received per operator (integer division with truncation will do).

#### Invalid Input Handling:
If any value read is not valid input, print the message "INVALID".

#### Assumptions:
Assume the availability of a variable, `stdin`, that references a `Scanner` object associated with standard input.

#### Example Code:
Below is an example code snippet that handles this:

```java
callsReceived = stdin.nextInt();
operatorsOnCall = stdin.nextInt();
if (operatorsOnCall == 0)
    System.out.print("INVALID");
else
    System.out.print(callsReceived / operatorsOnCall);
```

### Explanation:
1. **Reading Input**:
   - The code uses the `Scanner` object `stdin` to read integer inputs for `callsReceived` and `operatorsOnCall`.

2. **Validation Check**:
   - The `if` statement checks if `operatorsOnCall` is zero. If true, it prints "INVALID" because dividing by zero is not permissible.

3. **Division and Output**:
   - If `operatorsOnCall` is not zero, it proceeds to print the result of `callsReceived` divided by `operatorsOnCall`.

### Execution Details:
- The script must handle both valid and invalid inputs gracefully.
- The message "INVALID" is output only when attempting to divide by zero.

### Code Submissions:
- Multiple attempts might be necessary to ensure the code is free of errors.
- The output includes feedback in case of compilation errors.

#### Example Output:
When executed, the program will either print the result of the division or the message "INVALID" depending on the input values provided.

---

### Important Note:
Ensure the code handles all edge cases, such as non-integer inputs and zero operators, to prevent runtime errors and ensure robust performance.
