In this problem, you will create a program that implements exception propagation across multiple methods, catches it at the appropriate caller level, and displays the result to standard output.

Exception Propagation

When an exception is not caught within a method, it propagates to the caller.

Propagation Mechanism

void methodA() {
  methodB(); // Exception occurs in methodB
}
void methodB() {
  throw new Exception(); // Exception here, propagates to methodA
}

Learning Points

• Exceptions propagate up the call stack
• Catching at the right place is important
• Unhandled exceptions terminate the program
