6.1 Data Types

PRIMITIVE DATA TYPES

NOTES

• Integer data types are 2's complement signed integers.
• Floating point data types are IEEE 754 floats.
• The char type can be represented in your code by a character delimited by ' quotes, such as:

       char the_letter_a='a';
  

• The boolean datatype is rarely used explicitly. Rather, it is normally created by using boolean operators.
• The void data type can only be used in a method declaration. You use it to declare a method that does not return anything. It can't be used for variables - what would they hold?
