Exception Propagation in Java

Exception Propagation sits inside exception handling. try holds risky code. catch runs backup code. finally runs cleanup (close file / connection) whether error happened or not.

throw sends an exception. throws declares a checked exception on the method. Empty catch blocks hide bugs — print or log the message.

Checked exceptions must be handled or declared. Unchecked (RuntimeException family) usually are not declared. Catch specific types first, then broader ones.

Let's take this on the board with one tiny Main class — no extra files. Output: Asha scored 72 then Pass. Real Main. Swap marks/name to show one idea from Exception Propagation in Java. Start from main, go line by line, and stop at each print. That output is the proof for Exception Propagation.
