Line 23 in method1’s try block calls method2. Line 36 in method2’s try block calls method3. In method3, line 47 throws a new Exception. Because this statement is not in a try block, method3 terminates, and the exception is returned to the calling method (method2) at line 36. This statement is in a try block; therefore, the try block terminates and the exception is caught at lines 38–41. Line 40 in the catch block throws a new exception.
