What Is the Meaning of Primitive Data Type in Java?
In Java, a primitive data type is a basic data type that is predefined by the language and is not an object. The primitive data types in Java are used to store simple values such as numbers, characters, and boolean values.
Numeric Primitive Data Types:
Java provides several numeric primitive data types:
- byte: This data type can store whole numbers from -128 to 127.
- short: It stores whole numbers from -32,768 to 32,767.
- int: It is used to store whole numbers from -2,147,483,648 to 2,147,483,647.
- long: This data type is used for larger whole numbers and can range from -9,223,372,036,854,775,808 to 9,223,372,036,854775807.
- float: It stores fractional numbers with floating-point precision. It has a range of approximately +/-3.40282347E+38F.
- double: This data type is used for storing larger fractional numbers and has a range of approximately +/-1.79769313486231570E+308.
Character Primitive Data Type:
The character primitive data type in Java is called ‘char’. It is used to store a single character or letter enclosed within single quotes (‘). For example: ‘A’, ‘5’, ‘#’, etc.
Boolean Primitive Data Type:
The boolean primitive data type is used to store only two possible values: true or false. It is commonly used for logical operations and conditions.
In summary, primitive data types in Java are the basic building blocks for storing simple values. These include numeric data types such as byte, short, int, long, float, and double; character data type ‘char’; and boolean data type ‘boolean’. Understanding these primitive data types is essential for successfully working with Java programming.
