Which primitive type is used to represent true/false values in Java?

• A. int
• B. boolean
• C. float
• D. char

Answer: (B)

The primitive type used to represent true/false values in Java is boolean. This type can hold only two possible values: true or false. It is specifically designed for logical operations and conditions, making it an essential part of control flow in programming, such as if statements and loops.

Using boolean allows developers to efficiently manage and evaluate conditions without needing to rely on other data types, which may represent true and false in a more indirect way. For example, integers can be used in conditional expressions (where 0 is often treated as false and any non-zero value as true), but using a boolean type is clearer and more semantically appropriate for indicating logical states.

Other primitive types like int, float, and char do not serve the purpose of representing true/false values and are used for numeric and character data, respectively, making boolean the distinct and correct choice for this question.
