28-32: Consider making the loop count configurable.The hard-coded value of 1000 iterations makes the code inflexible. Consider extracting this to a constant or configuration parameter.
+private static final int LEGACY_MODE_MULTIPLIER = 1000; } else if (MODE_LEGACY.equals(mode)) { - for (int i = 0; i < 1000; i++) { + for (int i = 0; i < LEGACY_MODE_MULTIPLIER; i++) { placeOrder(qty, side); } }
19-22: Enhance the demo with more comprehensive test cases.Consider adding test cases for edge scenarios like unknown servers and different order types to better demonstrate the system's behavior.
public static void main(String[] args) { processOrder("ServerA", 100, "BUY"); processOrder("ServerB", 100, "BUY"); + + // Demonstrate different order types + processOrder("ServerA", 50, "SELL"); + + // This would throw an exception with the suggested error handling + // processOrder("UnknownServer", 100, "BUY"); }
35-37: Consider adding input validation to the placeOrder method.While the current implementation is simple, adding basic validation for quantity and side parameters would make the code more robust.
public static void placeOrder(int qty, String side) { + if (qty <= 0) { + throw new IllegalArgumentException("Quantity must be positive"); + } + if (side == null || side.trim().isEmpty()) { + throw new IllegalArgumentException("Side cannot be null or empty"); + } System.out.println("Placed order: " + side + " " + qty + " shares"); }

6-17: Well-structured configuration setup.The use of constants for mode definitions and static initialization for server configuration follows good practices. The separation of concerns between mode definitions and server mapping is clean.

Remove the UI artifact from the import statement.
There appears to be a UI artifact "Add commentMore actions" appended to the import statement that should be removed.

In OrderProcessor.java at line 1, remove the UI artifact text "Add commentMore
actions" that is appended to the import statement. Ensure the import statement
only contains valid Java import syntax without any extra text.

Add error handling for unknown servers and consider the legacy behavior impact.
The method has two significant concerns:
- Missing error handling: Unknown server names will result in
nullmode, causing the method to silently do nothing. - Legacy mode behavior: The 1000x order placement in legacy mode appears intentional but could have severe business impact in a real system.
public static void processOrder(String server, int qty, String side) {
String mode = serverModes.get(server);
+ if (mode == null) {
+ throw new IllegalArgumentException("Unknown server: " + server);
+ }
+
if (MODE_NEW.equals(mode)) {
placeOrder(qty, side);
} else if (MODE_LEGACY.equals(mode)) {
+ System.out.println("WARNING: Legacy mode will place order 1000 times");
for (int i = 0; i < 1000; i++) {
placeOrder(qty, side);
}
}

In OrderProcessor.java around lines 24 to 33, add error handling for cases where
the server name is unknown and the mode is null by logging an error or throwing
an exception. Also, review the legacy mode behavior that places 1000 orders in a
loop; consider adding a safeguard such as a configurable limit or confirmation
step to prevent unintended large order placements.
