What data type would you use to store a true or false value in Java?

The appropriate data type to store a true or false value in Java is boolean. In Java, the boolean type can hold one of two possible values: true or false. This binary state makes it ideal for representing conditions, controlling the flow of programs with conditional statements such as if statements or loops where decisions need to be made.

In contrast, the int data type is used for storing integer values and cannot directly represent true or false conditions. The char type is intended for single character values and does not relate to boolean logic. The String type is used for sequences of characters, making it suitable for text representations rather than boolean values that indicate a binary state. Thus, when you need to convey a truth value, you should always choose boolean as it is explicitly designed for that purpose.
