try catch program in java | Anil Dora | 2026

What is try–catch? try–catch is used to handle runtime errors (exceptions) so that the program does not terminate abnormally. Instead of JVM stopping the program, we handle the problem gracefully. Why try–catch is needed? Prevent abnormal termination Show user-friendly error messages Maintain normal program flow Separate error-handling code from business logic try block Definition try block contains the code that may cause an exception. Rules Risky code must be inside try A try block cannot exist alone Must be followed by catch or finally catch block Definition catch block handles the exception thrown from the try block. How it works (important theory) Error occurs inside try JVM creates an Exception object (e.g., ArithmeticException) JVM searches for a matching catch block If found → that catch executes Remaining try code is skipped Program continues after catch
