9/4/2023 0 Comments Java four basic data types![]() ![]() In the example below, a Java application is used to build several primitive data types. long 0L 8 byte Stores integer values from -2 63 to 2 63-1. Object: The object is an instance of a class. Example2: In real world, Alice is an object of the Human class. Example1: Blueprint of the house is class. It can be defined as a logical template that share common properties and methods. int 0 4 byte Stores integer values from -2 31 to 2 31-1. Class: The class is a blueprint (plan) of the instance of a class (object). short 0 2 byte Stores integer values from -32,768 to 32,767. float - stores floating point numbers, with decimals. int - stores integers (whole numbers), without decimals, such as 123 or -123. String values are surrounded by double quotes. In Java, there are different types of variables, for example: String - stores text, such as 'Hello'. byte 0 1 byte Stores integer values from -128 to 127. Variables are containers for storing data values. String values are surrounded by double quotes int - stores integers (whole numbers), without decimals, such as 123 or -123 float - stores floating point numbers, with decimals, such as 19.99 or -19. char ‘\u0000’ 2 byte Stores a single character/letter or ASCII value. In Java, there are different types of variables, for example: String - stores text, such as 'Hello'. Java’s basic data types are detailed in the table below: Data Types Default value Memory Size Description boolean false 1 bit Stores true or false values. Strings, Interfaces, Classes, etc are examples of non-primitive data types.Boolean, char, byte, short, int, long, float, and double are examples of primitive data types.The JDBC driver provides support for the JDBC 4. In Java, there are two sorts of data types, which are listed below: The Microsoft JDBC Driver for SQL Server uses the JDBC basic data types to convert the SQL Server data types to a format that can be understood by the Java programming language, and vice versa. ![]() The operating system allocates memory to a variable based on its data type and determines what can be placed in the reserved memory. String: This is the most commonly used data type in MongoDB to store data, BSON strings are of UTF-8. ![]() Below are the enlisted MongoDB data types: 1. Understanding what data types are accessible and how data is stored, retrieved, and manipulated in a programming language is one of the most crucial aspects of learning any programming language. BSON data format supports various data-types. ![]()
