Flow Control - SCJP Sun Certified Programmer for Java Platform SE6 - page 237

6. method1 catches the exception on line 6. The catch block executes and the stack trace
is printed. Flow of control now continues normally for the remainder of this program.
7. method1 finishes executing normally, so control jumps back to main and End of main
displays. The program successfully runs to completion.
Here is the output of CheckedDemo when a ClassNotFoundException occurs:
Inside main
Inside method1
Inside method2
Inside method3

Exceptions on the Exam
Watch for questions on the exam that specifi cally test your knowledge of the Handle or
Declare Rule. Remember that declaring a checked exception does not magically take care
of the exception. It simply pushes the responsibility of handling that exception to some
other method, which means somewhere down the call stack a try statement is needed to
handle the exception and the compiler enforces this rule.
You should also know which common exceptions are runtime or checked exceptions.
For example, you should know that ArithmeticException and NullPointerException
are runtime exceptions, while IOException , ClassNotFoundException , and
InterruptedException are checked exceptions.
