Java Data_Types How To Use With Examples
Data-Types: A java Data type specifies the different sizes and values that can be stored in the variable. There are two types of data types in Java Language.
Primitive data types: Primitive data types in java boolean Data Types, char Data Types, byte Data Types, short Data Types, int Data Types, long Data Types, float Data Types, and double Data Types.
Non-primitive data types: A non-primitive data types include Classes, Interfaces, and Arrays.
Classes
Interface
Array
Primitive data types: Primitive data types in java boolean Data Types, char Data Types, byte Data Types, short Data Types, int Data Types, long Data Types, float Data.

Boolean Data Type: The Boolean knowledge kind is employed to store solely 2 potential values.True and False.
This knowledge kind is employed for easy flags that track true/false conditions.
The Boolean knowledge kind specifies one little bit of info, however, its "size" cannot be outlined exactly.
