Java Data Types ?

-The java has Two Type of Data Types.These Are

1. Primitive Data Types
2. Non-Primitive Data Types

• Primitive Data Types: (IT Has Eight Types)

1. byte - Stores small integers from -128 to 127(1 byte).
   Used only when memory optimization actually matters.

2. short - Stores integers from -32,768 to 32,767(2 bytes).
   Almost never used in real Java applications.

3. int - Stores whole numbers within 32-bit range(4 Bytes).
   Default and most commonly used integer type.

4. long - Stores very large whole numbers (64-bit)(8 Bytes).
   Use when int is not sufficient.

5. float - Stores decimal numbers with single precision().
   Not accurate for financial or precise calculations.

6. double - Stores decimal numbers with double precision.
   Default choice for decimal values in Java.

7. char - Stores a single Unicode character.
   Uses 2 bytes and supports international characters.

8. boolean - Stores only true or false.
   Used for conditions and logical decisions.

-Non -Primitive Data Types:

1. String - Stores a sequence of characters as an object.
   Immutable and provides many built-in methods.

2. Array - Stores multiple values of the same type.
   Size is fixed once created.

3. Class - Blueprint used to create objects.
   Contains variables and methods together.

4. Object - Instance of a class stored in heap memory.
   Accessed using reference variables.

5. Interface - Defines method declarations without implementation.
   Used to achieve abstraction and multiple inheritance.

6. Enum - Stores a fixed set of named constants.
   Used for predefined, unchangeable values
