Back to Question 33

Answer 32

In Java, the scope can be reduced by placing it within a block of code within the method. The scope extends from the point at which it is declared to the end of the block of code in which it is declared.

Back to Question 32

Answer 31

A block of code is defined by enclosing it within curly brackets as shown below

{ ... } .

Answer 30

The scope of a local variable extends from the point at which it is declared to the end of the block of code in which it is declared.

Back to Question 30

Answer 29

In Java, local variables are declared within the body of a method or constructor, or within a block of code contained within the body of a method orconstructor.

Back to Question 29

Answer 28

A member variable is a member of a class ( class variable) or a member of an object instantiated from that class ( instance variable). It must be declared within a class, but not within the body of a method orconstructor of the class.

Back to Question 28

Answer 27

The scope of a variable places it in one of the following four categories:

  • member variable
  • local variable
  • method parameter
  • exception handler parameter

Back to Question 27

Answer 26

The scope of a Java variable is the block of code within which the variable is accessible.

Back to Question 26

Answer 25

The rules for Java variable names are as follows:

  • Must be a legal Java identifier consisting of a series of Unicode characters.
  • Must not be the same as a Java keyword and must not be true or false.
  • Must not be the same as another variable whose declaration appears in the same scope.

Back to Question 25

Answer 24

In Java, a legal identifier is a sequence of Unicode letters and digits of unlimited length. The first character must be a letter. All subsequentcharacters must be letters or numerals from any alphabet that Unicode supports. In addition, the underscore character ( _ ) and the dollar sign ( $ ) are considered letters and may be used as any character including the first one.

Back to Question 24

Answer 23

False. The name of a reference variable evaluates to either null, or to information that can be used to access an object whose reference has been storedin the variable.

Back to Question 23

Answer 22

Later versions of Java support either syntax shown in Listing 1 .

Listing 1 . Listing for Answer 22.
class test{ public static void main(String[]args){ Double var1 = 5.5;double var2 = var1.doubleValue(); System.out.println(var2);double var3 = var1; System.out.println(var3);}//end main }//end class test

Back to Question 22

Answer 21

The proper syntax for early versions of Java is shown below. Note the upper-case D . Also note the instantiation of a new object of type Double .

Double myWrappedData = new Double(5.5);

Later versions of Java support the following syntax with the new object of type Double being instantiated automatically:

Double myWrappedData = 5.5;

Back to Question 21

Answer 20

The proper syntax is shown below. Note the lower-case d .

double myPrimitiveData = 5.5;
