Exam 12: Exception Handling

Match each term with the correct statement below. -Object-oriented techniques to manage errors

____ exceptions are the type that programmers should anticipate and from which programs should be able to recover.

Match each term with the correct statement below. -Constructs a new exception with the specified detail message

What things might a programmer do to cause a potential exception in a program?

Some programmers refer to a catch block as a catch ____.

When you have actions you must perform at the end of a try…catch sequence, you can use a ____ block.

import java.util.*; public class DivisionMistakeCaught3 { public static void main(String[] args) { Scanner input = new Scanner(System.in); int numerator, denominator, result; try { System.out.print("Enter numerator >> "); numerator = input.nextInt(); System.out.print("Enter denominator >> "); denominator = input.nextInt(); result = numerator / denominator; System.out.println(numerator + " / " + denominator + " = " + result); } catch(ArithmeticException mistake) { System.out.println(mistake.getMessage()); } catch(InputMismatchException mistake) { System.out.println("Wrong data type"); } } } Using the above code, describe what will happen if a user enters two usable integers. What will happen if a user enters an invalid noninteger value? What will happen if the user enters 0 for the denominator?

Which method constructor constructs a new exception with the specified detail message and cause?

____ represents the degree to which a system is resilient to stress, maintaining correct functioning.

If you create an object using Java's BigDecimal class, and then perform a division that results in a non-terminating decimal division such as 1/3, but specify that an exact result is needed, a(n) ____________________ is thrown.

The parent class of Error is ____.

public class exceptions { public static void main(String Args[]) { int[] array = new int[3]; try { for(int a=0;a<4;++a) { array[a] = a; } System.out.println(array); } catch(ArrayIndexOutOfBoundsException e) { System.out.println("Out of bounds"); } } } In the above code, the line System.out.println(array); gets skipped when an exception occurs. Write a finally block that will execute, and will execute a System.out.println(array); if there is an exception.

A(n) ____ clause is used in the method header so that applications that use your methods are notified of the potential for an exception.

public static void main(String args[]) { int a, b; try { a = 0; b = 42 / a; System.out.println("This will not be printed."); } catch (ArithmeticException e) { System.out.println("Division by zero."); } System.out.println("After catch statement."); } The program above includes a try block and a catch clause that processes the ArithmeticException generated by the division-by-zero error. Explain how the try and catch blocks operate, and what the output will be following program execution.

What advantage to programmers does the technique of cycling through the methods in the stack offer? Why?

Any ____________________ block might throw an Exception for which you did not provide a catch block.

Match each term with the correct statement below. -A process that is crucial to an organization

The ____ class represents more serious errors from which your program usually cannot recover.

Match each term with the correct statement below. -Constructs a new exception with the specified cause and a detail message of cause.toString()

The keyword catch followed by an Exception type in the method header is used when a method throws an exception that it will not catch but that will be caught by a different method.
