Java Data Types - W3Schools
A primitive data type specifies the type of a variable and the kind of values it can hold. There are eight primitive data types in Java: Data Type Description; byte: Stores whole numbers from -128 to 127: short: Stores whole numbers from -32,768 to 32,767: int:
Java Primitive Data Types - Online Tutorials Library
Java data types define the type and value range of the data for the different types of variables, constants, method parameters, return types, etc. The data type tells the compiler about the type of data to be stored and the required memory. To store and manipulate different types of data, all variables must have specified data types.
Primitive data type vs. Object data type in Java with Examples
Primitive Data Type: In Java, the primitive data types are the predefined data types of Java. They specify the size and type of any standard values. Java has 8 primitive data types namely byte, short, int, long, float, double, char and boolean. When a primitive data type is stored, it is the stack that the values will be assigned.
Java Data Types And Variables – Explained for Beginners
When passing a primitive data type as a method argument, a copy of the value is passed, while passing a reference data type passes the reference by value. These differences shows how important storage, default values, size, operations, and pass-by-value semantics between reference data types and primitive data types work in Java.

Java Data Types - DataCamp
Java data types are the foundation of data manipulation in Java programming. They define the size and type of values that can be stored in a variable. Java is a statically typed language, meaning every variable must be declared with a data type before use. Java data types are categorized into two main groups: primitive data types and reference ...
What is a Data Type? - W3Schools
In Java, the null keyword can only be assigned to non-primitive data type variables, like strings or arrays. C++ does not have a direct equivalent to null, or None, but the nullptr keyword can be used to indicate that a pointer points to nothing. Binary Values and Data Types. In computers, all data is stored as sequences of 0s and 1s.

The Definitive Guide to Java Data Types to Get You Started - Adeva
In Java, an array is an object used to store a group of values of the same data type. These values can be of primitive or non-primitive data types. In Java arrays: Have fixed length specified during creation. Elements in an array starting at index 0, and second element 1, and so on. Have fast access due to indexing. Syntax:
Java Data Types - W3Schools
Every variable in Java has a data type which tells the compiler what type of variable it as and what type of data it is going to store. Data type specifies the size and type of values. Information is stored in computer memory with different data types. Whenever a variable is declared, it becomes necessary to define a data type that what will be ...

There are three reference data types in Java: class types, interface types, and array types. Primitive types are used to store values, while reference types are used to store references to the values.
Data Types in Java You Need to Know - Udacity
Primitive types are Java’s fundamental data types — integers, floating-point numbers, booleans and characters. Primitive types are limited in the type of data and values they represent, but form the basis for creating more complex user-defined data types. Integers. Integers are a data type used for representing whole numbers, such as 20 or -5.
