Maintain clean, professional code by removing development artifacts and improving readability:

1. Remove debug code before committing:
   • Delete all debugging print statements
   • Remove commented-out code blocks
   • If keeping temporarily disabled code is necessary, add a clear TODO comment

   // Bad:
   System.out.println("Functrace on: " + funcTrace);
      
   // Bad:
   // ptrDataBuffer.closeBuffer();
   // if(pointer != null && !pointer.isNull())
   //     pointer.close();
      
   // If really necessary:
   // TODO: Re-enable this after fixing JIRA-1234
   // ptrDataBuffer.closeBuffer();
   

2. Replace magic numbers with named constants:
   • Extract hard-coded numeric literals into meaningful constants
   • Place constants at the class level for reuse and clarity

   // Bad:
   if (edgeCount - lastEdgeCount > 10000) {
     // ...
   }
      
   // Good:
   private static final int EDGE_COUNT_REPORT_THRESHOLD = 10000;
      
   if (edgeCount - lastEdgeCount > EDGE_COUNT_REPORT_THRESHOLD) {
     // ...
   }
   

3. Format precondition checks properly:
   • Use string formatting instead of concatenation to avoid unnecessary object creation
   • Include the actual values in the error message for easier debugging

   // Bad:
   Preconditions.checkArgument(data >= 0,
           "Values for " + paramName + " must be >= 0, got: " + data);
      
   // Good:
   Preconditions.checkArgument(data >= 0, "Values for %s must be >= 0, got %s", paramName, data);
   

4. Add private constructors to utility classes:
   • Prevent instantiation of utility classes with private constructors

   // Good:
   public class ValidationUtils {
       private ValidationUtils() {
           // Private constructor to prevent instantiation
       }
          
       // Static utility methods...
   }
