Answers

Answer 9

If you don't provide matching parentheses to control the order of evaluation, the order will be determined by the precedence of the operators with theoperations having higher precedence being evaluated first. For example, multiply and divide have higher precedence than add and subtract.

Back to Question 9

Answer 8

You can control the order of evaluation by the use of matching parentheses.

Back to Question 8

Answer 7

False. Java does not support a constant type. However, in Java, it is possible to achieve the same result by declaring and initializing a variable andmaking it final .

Back to Question 7

Answer 6

The syntax for creating a named constant in Java is shown below.

A named constant in Java final float PI = 3.14159;

Back to Question 6

Answer 5

True. Java supports named constants that are constructed using variable declarations with the final keyword.

Back to Question 5

Answer 4

A method call evaluates to the value returned by the method.

Back to Question 4

Answer 3

An expression is a specific combination of operators and operands that evaluates to a particular value. The operands can be variables, constants, ormethod calls.

Back to Question 3

Answer 2
