The ex.printStackTrace() method is commonly used to print the stack trace of an exception to the standard error stream. It's useful during debugging but not recommended for use in production code, as it can expose sensitive information and isn't considered a best practice for error handling. Instead, it's better to use logging frameworks like Log4j or SLF4J for logging exceptions.
The ex.getMessage() method is a suitable alternative because it retrieves the detail message string of the throwable object, which can then be logged appropriately without exposing the stack trace. Here's an example of how you might use it:
Java
try {
// risky operations that might throw an exception
} catch (Exception ex) {
logger.error(ex.getMessage());
}

In this code snippet, logger.error() is a method provided by a logging framework, which you would use in place of ex.printStackTrace(). This method logs the error message at the error level, which is typically configured to be output to a log file for later analysis.
