Data Type

• Primitive Data Types:

  • int: Used for integers (e.g., 1, 100, -500).

  • double: Used for floating-point numbers (e.g., 3.14, -0.5, 2.0).

  • char: Used for single characters (e.g., 'A', 'b', '$').

  • boolean: Used for true or false values.

  • long: Used for large integers.

  • float: Used for floating-point numbers with smaller precision than double.

  • short: Used for small integers.

  • byte: Used for very small integers.

• Reference Data Types:

  • Objects: Variables can also reference objects of various classes in Java.

  • Arrays: Variables can hold arrays of any data type.
