Question

What is causing this error?

This image depicts a simple Java program designed to record the number of pizzas sold over several days. Below is a transcription and explanation of the code and output:

### Code Explanation:

1. **Imports**:
- The `Scanner` class is used to take input from the user.

2. **Class and Variables**:
- `NUM_DAYS` is set to 6, which should represent the number of days sales data will be collected for.
- `REV_PIZZA` is a constant that signifies the revenue per pizza, set at $8.50.
- Arrays and counters (`nPizza`, `iWeek`, and `iDay`) are declared to store the number of pizzas sold and track weeks and days.

3. **Main Method**:
- A `Scanner` object named `input` is instantiated to read data from the user.
- The program prompts the user to enter the number of pizzas sold for each day.

4. **For Loop**:
- Iterates over the number of days (`NUM_DAYS`).
- Prompts the user to input the number of pizzas sold for each day (Day 1 to Day 6).
- Validates the input to ensure non-negative values; an error message is displayed if a user enters a negative value.

5. **Output**:
- The program takes input for each day and resets if a negative value is entered.

### Console Output:

- Prompts user to enter the number of pizzas sold for each day.
- In the provided output:
- Day 1: User inputs -1, which is invalid, prompting a message: "Invalid value. Please enter a valid value."
- Days 3 and 5: User inputs -5 and -7, respectively, which also trigger the invalid value message.
- Days 2, 4, 6, and 7: User inputs valid non-negative numbers.

This code demonstrates basic input validation and array usage in Java to manage simple datasets such as daily sales figures.
