Exception Handling & Error Management 🚧

Intermediate

Robust Java applications handle errors gracefully using exception handling mechanisms.

Exceptions are issues that disrupt normal program flow, such as NullPointerException or IOException.

try-catch Blocks:

  • Wrap risky code in try blocks.
  • Catch specific exceptions with catch.
  • Optionally include finally for cleanup.

Example:

try {
    int result = 10 / 0;
} catch (ArithmeticException e) {
    System.out.println("Cannot divide by zero!");
} finally {
    System.out.println("Operation completed.");
}

Proper exception handling enhances application stability and user experience by managing unforeseen errors effectively.
