Java Part-19 | Java Data Types (Gujarati)

Data types are divided into two groups:
• Primitive data types - includes byte, short, int, long, float, double, boolean and char
• Non-primitive data types - such as String, Arrays and Classes

Primitive Data Types:
• A primitive data type specifies the size and type of variable values, and it has no additional methods.
• There are eight primitive data types in Java:

Non-Primitive Data Types
• Non-primitive data types are called reference types because they refer to objects.
The main difference between primitive and non-primitive data types are:
• Primitive types are predefined (already defined) in Java. Non-primitive types are created by the programmer and is not defined by Java (except for String).
• Non-primitive types can be used to call methods to perform certain operations, while primitive types cannot.
• A primitive type has always a value, while non-primitive types can be null.
• A primitive type starts with a lowercase letter, while non-primitive types starts with an uppercase letter.
• The size of a primitive type depends on the data type, while non-primitive types have all the same size.
