Answer 16

Question 17

True or false? Java supports two different floating point types:

  • float
  • double

Answer 17

Question 18

True or false? The purpose of the char type is to make it possible to represent the letters of the alphabet, the punctuation characters,and the numeric characters internally in the computer. This is accomplished by assigning a numeric value to each character.

Answer 18

Question 19

True or false? The char type uses a standard character representation known as Unicode to represent up to 65,535 different characters.

Answer 19

Question 20

True or false? In Java, you usually represent a character in your program by surrounding it with quotation marks as shown below:

Answer 20

Question 21

True or false? The boolean type can have three values:

  • true
  • false
  • maybe

Answer 21

Question 22

True or false? Java is an extensible programming language, meaning that there is a core component to the language that is always available. Beyondthe core component, different programmers can extend the language in different ways to meet their individual needs.

Answer 22

Question 23

True or false? As is the case in C++, one of the ways that individual programmers can extend the Java language is to create overloaded operators forthe primitive types.

Answer 23

Question 24

True or false? One of the ways that individual programmers can extend the Java language is to create new types.

Answer 24

Question 25

True or false? The specific Java mechanism that makes it possible for programmers to define new types is a mechanism known as the class definition .
