Chapter 9.2, Problem 18STQ
Program Plan Intro
Exception:
- • It is nothing but an undesirable or unexpected event that occurs at run time which interrupts the normal flow of the
program ’s commands. - • Exception handling is a
mechanism that handle runtime errors like “ClassNotFoundException”, “SQLException”, and so on. - • An advantage of exception handling is to maintain a flow of the program.
- • An exception can be handled using “try” and “catch” block.

Suppose the exception class CrazyException is defined as follows: public class CrazyException extends Exception { public CrazyException() { super("Crazy exception thrown!"); System.out.println("Wow, Crazy exception thrown!"); } public CrazyException(String message) { super(message); System.out.println("Wow, crazy exception thrown with "+ "an argument!"); } public void crazyMethod() { System.out.println("Message is " + getMessage()); } } What output would be produced by the following unlikely code? CrazyException exceptionObject = new CrazyException(); System.out.println(exceptionObject.getMessage()); exceptionObject.crazyMethod();
Suppose the exception class TestException is defined as follows:public class TestException extends Exception{public TestException(){super("Test Exception thrown!");System.out.println("Test exception thrown!!");}public TestException(String message){super(message);System.out.println("Test exception thrown with an argument!");}public void testMethod(){System.out.println("Message is " + getMessage());}}What output would be produced by the following code (which is just anexercise and not likely to occur in a program)?TestException exceptionObject = new TestException();System.out.println(exceptionObject.getMessage());exceptionObject.testMethod();The class TestException is on the website that comes with this text.

The class should have a default constructor. If an exception is thrown using zero-argument constructor, getMessage should return "Cor Breach Evacuation Ship!" The class should also define a constructor having a single parameter of type String.

- Defined Exception Handling Exception Handling is used to overcome exceptions that take place during programs’ execution in a systematic manner. For instance, dividing a number by ‘0’ is a mathematical error (not defined). As you learned in class, you can use exception handling to overcome such operations. If you write a code without using exception handling, then the output of division by zero will be shown as infinity which cannot be further processed. Consider the following code: float Division(float num, float den) {return (num / den);} int main() { float numerator = 12.5; float denominator = 0; float result; result = Division(numerator, denominator); cout << "The quotient of 12.5/0 is " << result << endl; }arrow_forwardDefine an exception class called CoreBreachException. The class should have a default constructor. If an exception is thrown using this zero- argument constructor, getMessage should return "Core Breach! Evacuate Ship!" The class should also define a constructor having a single parameter of type String. If an exception is thrown using this constructor, getMessage should return the value that was used as an argument to the constructor.arrow_forwardJAVA programming languagearrow_forward
