What is Variable Class Java?
In Java, a variable class refers to the data types that define the kind of values a variable can hold. These can be divided into two main categories: primitive types (like int
, float
, char
, and boolean
) and reference types (like objects and arrays). Each class manages a specific type of data, providing methods for manipulation. For instance, the Integer
class wraps the primitive int
, offering utility methods. Variable classes are crucial for type safety, memory management, and ensuring that operations performed on variables are appropriate for the data type.
