Question
The following Java program is intended to take an integer limit from the command line and return the sum of all the even integers between 0 and the limit inclusive (we assume the input is an integer here). The code does not work as intended. Describe the changes to be made in the code so that the correct sum is calculated.

```java
public class LoopOne
{
    public static void main(String[] args)
    {
        // Even Steven
        int esum = 0;
        int count = 0;
        int limit = Integer.parseInt(args[0]);
        StdOut.println("Sum the Even Numbers");
        while (count <= limit)
        {
            if (count % 2 == 0) esum = esum + count;
            count++;
        }
        StdOut.print("The sum of the even numbers up to " + limit + " is " + esum);
    }
}
```

### Explanation

This Java program reads an integer limit from the command line and computes the sum of all even numbers up to and including that limit. The main issues are explained and corrected below:

1. **Initialization and Loop Condition:**
   - Initially, the count is set to 0 and is incremented with each loop iteration.
   - Ensure that the loop continues as long as `count` is less than or equal to `limit`.

2. **Correct Use of Conditional Statements:**
   - The program uses `if (count % 2 == 0)` to identify even numbers, which is correct.

3. **Output Correction:**
   - The output description correctly conveys the result of the computation.

### Suggestion for Correctness

Verify that the input provided via command line arguments is indeed convertible to an integer to avoid runtime errors. Additionally, ensure that the `StdOut` class or its equivalent is correctly imported and used.
