Exception handling in Java is a powerful mechanism that allows developers to manage runtime anomalies in a controlled manner. By using a combination of try, catch, and finally blocks, developers can capture and handle exceptions, ensuring that the program continues to run without crashing unexpectedly. This is crucial for robust application development.
Java has a built-in hierarchy of exception classes, with the base class being Throwable
. Exceptions can be categorized into checked exceptions (which must be declared or handled) and unchecked exceptions (which do not require explicit handling).
Here's a simple example demonstrating exception handling in Java:
try {
// Code that may throw an exception
int result = 10 / 0; // This will cause an ArithmeticException
} catch (ArithmeticException e) {
// Handling the ArithmeticException
System.out.println("Cannot divide by zero: " + e.getMessage());
} finally {
// This block will execute regardless of an exception
System.out.println("Execution completed.");
}
