This commit introduces a new Python script, `fix_constructors.py`, which scans Java files for constructors that do not match their enclosing class names. The script identifies misnamed constructors and corrects them, ensuring that all constructors adhere to Java's naming conventions. It processes all Java files within a specified directory and reports the number of files modified.
