Data Types define the type of data which will be stored in the variable or a data structure. In Java, there are two datatypes that are Primitive Data Type and Non Primitive Data Types in Java. Here our main focus will be on the Non Primitive Data Types in Java. So let\u2019s begin with the introduction to Data Type in Java.<\/p>\n
In a programming language, data types are used to define the kind of data that is to be stored in a variable. Java primitive data types are the ones that are predefined by the programming language which in this case is Java. There are in particular two forms of Data types in java:<\/p>\n
Java has a set of data types that are already defined within the language, known as primitive data types. A primitive data type states the size, type of variable values, and no additional methods. There are mainly 8 types of primitive data types in Java:<\/p>\n
Float:<\/strong> Stores the fractional numbers and is capable of storing 6 to 7 decimal digits<\/p>\n Short:<\/strong> Stores numbers from -32,768 to 32,767<\/p>\n Long:<\/strong> Stores numbers from -9,223,372,036,854,775,808 to 9,223,372,036,854,775,807<\/p>\n Int:<\/strong> Stores numbers from -2,147,483,648 to 2,147,483,647<\/p>\n Bytes:<\/strong> Stores numbers from -128 to 127<\/p>\n Double:<\/strong> Stores fractional numbers. Capable of storing 15 decimal digits<\/p>\n Char:<\/strong> Stores a single character\/letter as well as ASCII values<\/p>\n Boolean:<\/strong> Stores only true or false.<\/p>\n Example of Primitive Data Types in Java:<\/strong><\/p>\n Non primitive data types in Java are also known as reference types. Non-primitive data types in Java are not pre-defined by the programming language itself, unlike primitive data types. Instead, they are created by programmers as needed for their programs. The users can effortlessly create and Also can modify this easily. They can store a couple of values and methods to sure certain tasks. Non Primitive data types in Java are not predefined. Non primitive data types in Java are consumer\u2013defined data types.<\/p>\n Whilst we define a variable of non primitive data types in Java, it references a memory place wherein data is saved in the heap memory. That is, it references a memory where an item is clearly located.<\/p>\n Consequently, a non-primitive data type variable is also referred as a referenced data type in Java or an absolute object reference variable.<\/p>\n This object reference variable lives in the stack memory and the object to which it points constantly lives in the heap memory. The stack holds a pointer to the items on the heap. The following are the different types of Non Primitive Data Types in Java.<\/p>\n Class & Objects:<\/strong> Example:<\/strong><\/p>\n\t\t\t\t\t\tint number = 3;\nfloat myfloatnumber = 3.2f;\nchar ch = \u2018A\u2019;\nBoolean flag = false;\nString str = \u201chello\u201d;<\/code><\/pre>\nNon Primitive Data Types in Java<\/h2>\n
\nAll non primitive data types in Java are simply referred as objects which might be created through instantiating a class.<\/p>\nKinds of Non Primitive Data Types<\/h3>\n
\n
\nClass in Java is a user-defined data type. It is designed by the programmer and serves as a template or blueprint for creating data structures. It consists of member variables and methods that define its behavior. An object is an instance of a class, which can access the member variables and methods of the class.<\/p>\n
