1) The purpose of Exception handling (using try...catch) is to handle common errors in your program.
- True
- False
2) Which of the following are examples of common exceptions? ( you can choose more than 1 if applicable)
- arithmetic overflow
- division by zero
- memory exhaution
- array index in bounds
3) When a try block is executedbut no exceptions are thrown, where does control pass when the try block has completed axecution?
- The last catch block.
- The finally block, if there is one, otherwise to the code after the last catch.
- The code after the last catch block.
- None of the above.
4) What happens if no catch handler matches the type of a thrown object?
- If there is a finally block, it is axecuted and a search for the match is continued in the next enclosing try statement.( If no match is found, the program thread terminates early).
- The program thread terminates early.
- The exception is ignored.
- None of the above.
5) What happens if multiple catch blocks match the type of thrown object?
- The last one matches the exception is executed.
- The current program thread stops executing.
- The first catch block afterthe try that matches the exception is executed.
- None of the above.
6) The exception thrown by the Scanner class when executing method nextInt, and invalid chars are entered for the int is:
- ArithmeticException
- IndexOutOfBoundsException
- InputMismatchException
- IOException
7) The exception thrown when the program executes a division where the denominator is 0 is:
- IOException
- ArithmeticException
-InputMismatchException
- None of the above
8) The difference between a checked exception and unchecked exception is:
-The compilor verifies that all checked exceptions thrown by each method are caught in the calling code (or declared in a throw clause).
- The JVM verifies that all checked exceptions thrown by each method are caught in the calling code (or declaredin a throw clause).
- Java catches all checked exceptions automatically if the programmer has not done so.
- None of the above.
9) Does declaring a catch of a superclass exception catch all of the subclasses exceptions of that superclass?
- True
- False
