data types

Java provides several data types to represent different kinds of values. Here are the commonly used data types in Java:

1. Primitive Data Types:
   • byte: 8-bit integer (-128 to 127)
   • short: 16-bit integer (-32,768 to 32,767)
   • int: 32-bit integer (-2,147,483,648 to 2,147,483,647)
   • long: 64-bit integer (-9,223,372,036,854,775,808 to 9,223,372,036,854,775,807)
   • float: 32-bit floating-point number
   • double: 64-bit floating-point number
   • boolean: represents true or false
   • char: 16-bit Unicode character (0 to 65,535)
2. Reference Data Types:
   • String: represents a sequence of characters
   • Array: represents a collection of elements of the same type
   • Class: represents a class or interface type
   • Interface: represents an interface type
   • Enum: represents an enumeration type
   • Object: represents any type of object
3. Other Data Types:
   • BigInteger: represents arbitrary-precision integers
   • BigDecimal: represents arbitrary-precision floating-point numbers
   • Date: represents a specific moment in time
   • Calendar: provides various calendar-related operations

These are the basic data types in Java, and you can also create your own custom data types using classes and structures.
