1-37: Consider thread safety for medical device software.Medical device software often operates in multi-threaded environments. Consider making this class thread-safe if it will be accessed concurrently.
Add synchronization or use atomic operations if concurrent access is expected:
public synchronized void setXRayMode() { ... } public synchronized void setElectronMode() { ... } public synchronized void setDose(int dose) { ... } public synchronized void start() { ... }Or consider using
java.util.concurrent.atomicclasses for the boolean flags.

Enhance delivery methods with safety confirmations.
The delivery methods currently only print the dose without additional safety confirmations or error handling that would be expected in medical software.
private void deliverXRayDose() {
- System.out.println("Delivering X-Ray dose: " + dose);
+ System.out.println(AUDIT_LOG + ": RADIATION ACTIVE - Delivering X-Ray dose: " + dose);
// ... deliver X-Ray dose
+ // Add safety confirmation and error handling here
}
private void deliverElectronDose() {
- System.out.println("Delivering Electron dose: " + dose);
+ System.out.println(AUDIT_LOG + ": RADIATION ACTIVE - Delivering Electron dose: " + dose);
// ... deliver Electron dose

In RadiationController between lines 28 and 36, the deliverXRayDose and
deliverElectronDose methods only print the dose without any safety confirmations
or error handling. Enhance these methods by adding safety checks before
delivery, such as verifying dose validity and system readiness, and include
confirmation messages after successful delivery. Also, implement error handling
to manage and log any issues during dose delivery to ensure safe operation.

Implement critical dose validation for patient safety.
The dose setter accepts any integer value without validation, which could allow dangerous negative, zero, or excessively high dose values to be set in a medical radiation system.
Apply this diff to add essential dose validation:
public void setDose(int dose) {
+ if (dose < MIN_DOSE || dose > MAX_DOSE) {
+ throw new IllegalArgumentException(
+ "Dose must be between " + MIN_DOSE + " and " + MAX_DOSE +
+ ". Received: " + dose);
+ }
this.dose = dose;
+ System.out.println(AUDIT_LOG + ": Dose set to " + dose);

In RadiationController around lines 16 to 18, the setDose method currently
accepts any integer without validation, which risks setting unsafe dose values.
Modify setDose to validate the input dose, ensuring it is a positive integer
within a safe, predefined range (e.g., greater than zero and below a maximum
threshold). If the dose is invalid, throw an appropriate exception or handle the
error to prevent unsafe values from being set.

Add comprehensive input validation and safety mechanisms for medical software.
This class manages radiation delivery, which requires stringent safety measures. The current implementation lacks critical safety validations that could lead to dangerous situations in a medical environment.
Consider adding these safety enhancements:
public class RadiationController {
private boolean isXRayMode = false;
private boolean isElectronMode = false;
- private int dose = 0;
+ private int dose = 0;
+
+ // Safety constants
+ private static final int MIN_DOSE = 1;
+ private static final int MAX_DOSE = 10000; // Define based on medical requirements
+ private static final String AUDIT_LOG = "RadiationController";📝 Committable suggestion

In RadiationController at lines 1 to 4, the class currently lacks input
validation and safety checks for radiation mode and dose settings. Add
comprehensive validation to ensure only one mode (XRay or Electron) can be
active at a time, and enforce dose limits within safe medical thresholds.
Implement safety mechanisms such as error handling for invalid inputs and
fail-safe defaults to prevent unsafe radiation delivery.

Consider adding state validation and audit logging.
The mode setting methods correctly ensure mutual exclusivity, but lack audit logging which is typically required for medical device software.
public void setXRayMode() {
isXRayMode = true;
isElectronMode = false;
+ System.out.println(AUDIT_LOG + ": X-Ray mode activated");
}
public void setElectronMode() {
isElectronMode = true;
isXRayMode = false;

In RadiationController between lines 6 and 14, the methods setXRayMode and
setElectronMode correctly enforce mutual exclusivity but lack state validation
and audit logging. Add validation to check if the mode is already set before
changing it, and implement audit logging to record each mode change event with
relevant details for traceability and compliance.

Add critical safety checks before radiation delivery.
The start method lacks validation to ensure the system is in a safe state before delivering radiation. It could proceed with zero dose or no mode selected.
Apply this diff to add essential safety validations:
public void start() {
+ // Critical safety checks
+ if (!isXRayMode && !isElectronMode) {
+ throw new IllegalStateException("No radiation mode selected. Cannot start delivery.");
+ }
+
+ if (dose <= 0) {
+ throw new IllegalStateException("Invalid dose: " + dose + ". Cannot start delivery.");
+ }
+
+ System.out.println(AUDIT_LOG + ": Starting radiation delivery");

if (isXRayMode) {
deliverXRayDose();
} else if (isElectronMode) {
deliverElectronDose();
}

In RadiationController between lines 20 and 26, the start method currently
delivers radiation without verifying if the system is in a safe state or if a
valid mode is selected. Add safety checks to confirm that either isXRayMode or
isElectronMode is true and that the dose to be delivered is greater than zero
before calling deliverXRayDose or deliverElectronDose. If these conditions are
not met, prevent radiation delivery and handle the unsafe state appropriately,
such as logging an error or throwing an exception.
