The character is not surrounded by apostrophes. It should be: 'W' .

With double quotes, "W", you get a String that contains a single character. This is not the same as a primitive single character. A String is represented as an object and may consist of several hundred bytes. A primitive character data item is always only two bytes.

Primitive Data Type boolean

Another of the primitive data types is the type boolean. It is used to represent a single true/false value. A boolean value can have only one of two values:

true     false

In a Java program, the words true and false always mean these boolean values. The data type boolean is named after George Boole, a nineteenth century mathematician, who discovered that a great many things can be done with true/false values. Although the amount of information in a boolean primitive is logically one bit, for convenience Java uses more than that to represent it.


Would you like a data type named after you someday?

  true     false
