Question

I need help with a Java question so that it can output them described in the image below:

import java.util.Scanner;

public class LabProgram {

    public static void sortArray(int[] myArr, int arrSize) {
        for (int i = 0; i < arrSize - 1; i++) {
            for (int j = 0; j < arrSize - i - 1; j++) {
                if (myArr[j] < myArr[j + 1]) {
                    // Swap elements if they are in the wrong order
                    int temp = myArr[j];
                    myArr[j] = myArr[j + 1];
                    myArr[j + 1] = temp;
                }
            }
        }
    }

    public static void main(String[] args) {
        Scanner scanner = new Scanner(System.in);

        // Read the number of elements in the array
        int arrSize = scanner.nextInt();
        int[] myArr = new int[arrSize];

        // Read and populate the array with elements
        for (int i = 0; i < arrSize; i++) {
            myArr[i] = scanner.nextInt();
        }

        // Call the sorting method
        sortArray(myArr, arrSize);

        // Output the sorted array
        for (int i = 0; i < arrSize; i++) {
            System.out.print(myArr[i]);
            if (i < arrSize - 1) {
                System.out.print(",");
            }
        }
        System.out.println();
    }
}

 

### Test Case Analysis: Sorting Function

This page provides an analysis of test cases for a sorting function, focusing on discrepancies between the actual output and expected results.

#### Test Case 1

- **Input**: `[5, 10, 4, 39, 12, 2]`
- **Your output**: `[39, 12, 10, 4, 2]`
- **Expected output**: `[39, 12, 10, 4, 2, ]`

**Issue**: The output is missing a trailing comma.

---

#### Test Case 2

- **Input**: `[3, 99, 3, 27]`
- **Your output**: `[99, 27, 3]`
- **Expected output**: `[99, 27, 3, ]`

**Issue**: The output is missing a trailing comma.

---

#### Test Case 3

- **Input**: `[1, 25]`
- **Your output**: `[25]`
- **Expected output**: `[25, ]`

**Issue**: The output is missing a trailing comma.

---

### Unit Test Analysis

- **Function call**: `sortArray([61, 92, 0, 22])`
- **Test feedback**: 
  - `sortArray([61, 92, 0, 22]) correctly returned [92, 61, 22, 0, ]`

The function executed successfully for this input, producing the correct result with the trailing comma included.

---

### Conclusion

The discrepancies highlighted indicate a consistent issue with missing trailing commas in the function's output. Adjustments are necessary to ensure that the output format matches the expected results consistently across tests.
