Data type in Java

DEV CommunityThursday, October 30, 2025 at 9:46:41 AM
Understanding data types in Java is essential for anyone looking to program effectively in this language. Java classifies data types into two main categories: primitive and non-primitive. Primitive data types, such as byte and short, are used to store specific ranges of whole numbers, which is crucial for memory management and performance. This classification helps developers choose the right type for their variables, ensuring efficient code execution and data handling.
