How many primitive data types are there in Java?

• A. 7
• B. 9
• C. 6
• D. 8 (byte, short, int, long, float, double, boolean, char)

Answer: (D)

Java uses a fixed set of primitive types for efficiency and low-level operations. There are eight of them: four integer types (byte, short, int, long), two floating-point types (float, double), one for true/false (boolean), and one for Unicode characters (char). This eight-type set is complete; there aren’t any other primitive types in Java. The count matches the option that lists all eight types explicitly. It’s also helpful to remember that there are wrapper classes (Byte, Short, Integer, Long, Float, Double, Boolean, Character) for use when objects are needed, but these are not primitive. Any other number would miss one of these primitive types.
