Primitive Data Types (Java in a Nutshell)David Flanagan
In other words, any data besides numbers goes into the char data type. Examples: char name = ‘John’ char country = ‘USA’ 8. Boolean: Boolean is the smallest data type in Java, i.e. it is made up of only one bit. Thus, a Boolean data type can have only two values – 0 (...
