What is Boolean false?
false is a primitive and Boolean. FALSE is an object, so they're not really comparable. If you assign false to a Boolean variable, like this: Boolean b = false; Java's auto boxing occurs to convert the primitive into an object, so the false value is lost and you end up with Boolean.
Why is boolean true?
Boolean. TRUE is a reference to an object of the class Boolean, while true is just a value of the primitive boolean type. Classes like Boolean are often called "wrapper classes", and are used when you need an object instead of a primitive type (for example, if you're storing it in a data structure).
What is Boolean example?
Answer: Boolean is a primitive data type that takes either “true” or “false” values. So anything that returns the value “true' or “false” can be considered as a boolean example. Checking some conditions such as “a==b” or “ab” can be considered as boolean examples.
Is 2 True or false?
