Types of Variables
Explore the different types of variables in Java, focusing on primitive and reference data types. Learn how these variables store data in memory using stack and heap, and understand key examples such as int, double, and String to build a strong foundation in Java programming.

In the last lesson, we saw how variables in Java have different types, e.g., int, boolean, etc. We can broadly classify these variable types, also called data types, into two categories:
- Primitive data types
- Reference data types
Primitive data types
The variables with primitive data types directly store the data, i.e., the primitive value is stored in memory reserved by a primitive variable. The primitive data type is the most basic data type in Java. There ...
