Answer 12

The increment operator may be used with both prefix and postfix notation. Basically, the increment operator causes the value of the variable towhich it is applied to be increased by one.

With prefix notation, the operand appears to the right of the operator (++X) , while with postfix notation, the operand appears to the left of the operator (X++) .

The difference in behavior has to do with the point in the sequence of operations that the increment actually occurs.

With the prefix version, the variable is incremented before it is used to evaluate the larger overall expression in which it appears. With the postfix version, the variable is used to evaluate the larger overall expression and then the variableis incremented.

Answer 11

The symbol for the increment operator is two plus signs with no space between them (++).

Back to Question 11

Answer 10

False: The increment operator is a unary operator.

Back to Question 10

Answer 9

The cast operator is used to purposely convert from one type to another.

Back to Question 9

Answer 8

The plus sign (+) is automatically overloaded in Java. The plus sign can be used to perform arithmetic addition. It can also be used to concatenatestrings. However, the plus sign does more than concatenate strings. It also performs a conversion to String type. When the plus sign is used to concatenate strings and one operand is a string, the other operand is automaticallyconverted to a character string before being concatenated with the existing string.

Answer 7

The operators listed in order are:

  • =
  • !=
  • +
  • (char)

where the cast operator is being used to cast to the type char .

Back to Question 7

Answer 6

Java does not support operator overloading by programmers.

Back to Question 6

Answer 5

For those languages that support it (such as C++) operator overloading means that the programmer can redefine the behavior of an operatorwith respect to objects of a new type defined by that program.

Back to Question 5

Answer 4

Both. As a binary operator, the minus sign causes its right operand to be subtracted from its left operand. As a unary operator, the minus sign causes the algebraic sign of the right operand to be changed.

Back to Question 4

Answer 3

An operator that operates on two operands is called a binary operator.

Back to Question 3

Answer 2

An operator that operates on only one operand is called a unary operator.

Back to Question 2

Answer 1

An operator performs an action on one or two operands.
