A catch block consists of four different elements: the keyword catch, followed by parentheses that contain an exception type and identifier, statements that take action to handle the error condition, an endcatch statement, and a return statement.

When appropriate, specialized ____ classes provide an elegant way for you to handle error situations.

 

Creating multiple methods with the same name, which will act differently and appropriately when used with different types of objects, is known as polymorphism.

____ is the process of creating a new, derived class from a base class.

 

When a variable is declared within a method, it ceases to exist when the method ends.

 

A method’s ____ consists of the method’s statements.

 

What will be the output of the below program? List what will be outputed to the screen and explain your answer.

class Class_name

      main()

           // Declarations

              num index

              num SIZE = 10

              num numbers[SIZE] = 0,0,0,0,0,0,0,0,0,0

            index = 0

            while index < SIZE

                  numbers[index]= index * 10

                  index = index + 1

            endwhile   

            output “The Output is: ”

            while index > 0

                  index = index – 1

                  output numbers[index]

            endwhile

      return

endClass

 

When illegal division by 0 takes place, an Exception object is not created automatically by the object-oriented language application.

 

You can write as many constructors for a class as you want, as long as they all have different ____ lists.

 

Overloaded methods have the same name and parameter lists.

 

When a main() method needs to use another method, it calls, or invokes it.

 

Multiple inheritance is the capability to inherit more than one method from a parent class.

 

A method can be used more than once within a program or in other programs.

 

Global variables are known to the entire class.

 

Methods are sometimes called ____.

 

A ____ reference is an automatically created variable that holds the address of an object and passes it to an instance method whenever the method is called.

 

What is the screen output of the following code segment? Explain the reasoning behind your answer.

Test1 = 70 
Test2 = 80 
Test3 = 84
NumberOfTests = 3 
Average = (Test1 + Test2 + Test3) / NumberOfTests

IF Average >= 90 THEN

   Output “Great job”

   Output “Your average is: ”, Average

ELSE

IF Average >= 80 or Average <=89 THEN 

   Output “Nice work”

   Output “Your average is: “, Average

ELSE

   Output : “Your Average is:”, Average

   Output “, You will do better next time!”

ENDIF
