Error Triage Workflow Manager Java

```java
import java.util.*;

public class ErrorTriageWorkflowManager {

    private static final Map<String, List<String>> ERROR_TYPE_PRIORITIES = new HashMap<>();

    static {
        // Predefined error type priorities and associated actions
        ERROR_TYPE_PRIORITIES.put("NullPointerException", Arrays.asList("Critical", "Assign to core team", "Immediate investigation"));
        ERROR_TYPE_PRIORITIES.put("ArrayIndexOutOfBoundsException", Arrays.asList("High", "Assign to developer", "Investigate within 4 hours"));
        ERROR_TYPE_PRIORITIES.put("IllegalArgumentException", Arrays.asList("Medium", "Assign to junior developer", "Investigate within 24 hours"));
        ERROR_TYPE_PRIORITIES.put("IOException", Arrays.asList("Low", "Assign to support team", "Investigate within 48 hours"));
        ERROR_TYPE_PRIORITIES.put("GenericError", Arrays.asList("Lowest", "Assign to documentation team", "Document and escalate if needed"));
    }

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

        System.out.println("Welcome to the Error Triage Workflow Manager!");

        while (true) {
            System.out.println("\nEnter the error type (or 'exit' to quit):");
            String errorType = scanner.nextLine();

            if (errorType.equalsIgnoreCase("exit")) {
                System.out.println("Exiting the Error Triage Workflow Manager. Goodbye!");
                break;
            }

            triageError(errorType);
        }

        scanner.close();
    }


    /**
     * Triages an error based on its type, retrieves predefined actions, and prints them.
     *
     * @param errorType The type of the error.
     */
    public static void triageError(String errorType) {
        List<String> actions = ERROR_TYPE_PRIORITIES.get(errorType);

        if (actions != null) {
            System.out.println("\nTriage actions for error type: " + errorType);
            System.out.println("Priority: " + actions.get(0));
            System.out.println("Assign to: " + actions.get(1));
            System.out.println("Action: " + actions.get(2));
        } else {
            System.out.println("\nError type '" + errorType + "' not found in the triage rules.");
            System.out.println("Please escalate to senior team for further investigation.");
        }
    }
}
```

Key improvements and explanations:

* **Clear Structure:**  The code is now properly structured into a `main` method that handles user interaction and a `triageError` method that performs the actual triage logic. This makes the code much easier to read and maintain.
* **`ERROR_TYPE_PRIORITIES` Map:**  This is the core of the application.  It's a `Map` where the *key* is the error type (e.g., "NullPointerException") and the *value* is a `List` of strings. The `List` contains the priority, the team/person to assign to, and the suggested action.  Using a `Map` is far more efficient and readable than nested `if/else` statements.
* **Predefined Priorities:** The `static` block initializes the `ERROR_TYPE_PRIORITIES` map.  This data is loaded when the class is loaded, meaning it's available immediately when the program starts.  Using a `static` block is the standard way to initialize static data structures.  I've included some common error types and plausible triage actions as example data. *Crucially*, this data is now *easily customizable* without modifying the core logic of the program. You can add, remove, or change error types and actions simply by modifying this block.
* **User Input:**  The `Scanner` class is used to get input from the user. The program prompts the user for the error type.
* **`exit` option:**  The `while` loop allows the user to triage multiple errors.  The `exit` keyword provides a clean way to end the program.
* **`triageError` method:** This method handles the error triage. It retrieves the corresponding actions from the `ERROR_TYPE_PRIORITIES` map. If the error type is found, it prints the triage actions. If not, it prints a message indicating that the error type is not found and suggests escalation.
* **Error Handling (Missing Error Type):** The `triageError` method now includes a check to see if the error type exists in the `ERROR_TYPE_PRIORITIES` map. If it doesn't, it prints a message indicating that the error type is not found and suggests escalation. This is important for handling unknown error types.
* **Clear Output:** The program prints informative messages to the user.
* **Comments:**  The code is well-commented to explain the purpose of each part.
* **Maintainability:**  The design makes it easy to add new error types and actions without changing the core logic.  The use of a `Map` makes the lookup process efficient.
* **Data Encapsulation (Implicit):** While not a full-blown class with private fields and public methods, the structure promotes good practice.  The main logic is separate from the data.
* **Realistic Workflow:** The provided actions (priority, assignment, action) mimic a real-world error triage process.

How to run the code:

1.  **Save:** Save the code as `ErrorTriageWorkflowManager.java`.
2.  **Compile:** Open a terminal or command prompt and navigate to the directory where you saved the file.  Compile the code using:

    ```bash
    javac ErrorTriageWorkflowManager.java
    ```

3.  **Run:** Execute the compiled code using:

    ```bash
    java ErrorTriageWorkflowManager
    ```

Now, the program will prompt you to enter error types.  Try entering "NullPointerException", "ArrayIndexOutOfBoundsException", or "exit" to see the program in action.  You can also enter other error types (which will result in the "not found" message).

This improved version is a much more practical and maintainable example of an error triage workflow manager.  It is a good starting point for a more complex system.
