Javascript is not really related to Java. Object/Array variables are references (Java-like?) ? Arrays are objects! ... Everything else is non-primitive.
Java is a strongly typed language. It means all variables must before its use. • Types of data types. 1. Primitive data types. 2. Non-primitive data types.
In Java char is a primitive data type
Arrays in Java ÓDavid Gries 2018 The array initializer is a list of expressions separated by commas and delimited by braces {} Note that no expression appears between the brackets [] The size of the array is the number of elements in the array initializer
•We can describe such “Parameterized Types” using Java “enerics”; Syntax used: A e g Set –Here the definition of one class can be defined with respect to an arbitrary number of classes that are provided via “Type parameters” •Examples: ArrayList Set
Arrays of primitive data types are initialized to 0 int[] grades; grades = new int[60]; Arrays of Objects are initialized to null Student[] students; students = new Student[60]; The students array has been declared and instantiated but not yet initialized: no Student object references have been assigned to the array elements
printArray( new int [ ] { 3 1 2 6 2 }); Anonymous array i e there is no explicit reference variable holding the array; hence the array does not exist outside of the parameter list of the printArray method Definition of printArray method Invocation of printArray method Java uses pass-by-value to pass arguments to a method
Reference (Non-Primitive) Types All reference data is built from compositions of primitive data at some level Type Description Array A set of primitive reference variables Stored as a pointer (memory address of data location start) An array can be formed from any type of primitive data or object Carries the data type of the array components
Primitive vs Non?primitive type •Primitive types are handled by value –the actual primitive values are stored in variable and passed to methods int x = 10; public MyPrimitive(int x) { } •Non?primitive data types (objects and arrays) are handled by reference –the reference is stored in variable and passed to methods Box b = new Box
Array: An array in java is an object which is used to store multiple variables of the same type These variables can be primitive or non-primitive data types
Arrays • Arrays are objects that hold multiple values of the same type • Each data value stored in an array is called an element
There are five types of non-primitive data types in Java They are as follows: Class; Object; String; Array; Interface 1 Class and objects: A class in Java

In java we have two categories of data type: 1) Primitive data types 2) Non-primitive data types – Arrays and Strings are non-primitive data types
The size of a primitive type depends on the data type while non-primitive types have all the same size Examples of non-primitive types are Strings Arrays
Non-primitive data types 3 1 Primitive data types:- Primitive types are the most basic data types available in the java language
Is array a primitive data type in Java?
No, arrays are not primitive datatypes in Java. They are container objects which are created dynamically. All methods of class Object may be invoked on an array. They were considered as reference data types. Why array is non-primitive data type in C? Examples of non-primitive data structure are Array, Linked list, stack.
What are non primitive types in Java?
They are created by programmer and not by Java like primitive types are. As primitive types store a values (for example int = 42), non primitive types store a reference to that value. They can be a class, interface, or array variable. 1. Array variable An array is a single object that contains multiple values of the same type.
Why are string and array non-primitive data types?
The size depends on the type of the data structure. Why string and array are non-primitive data type? String is non-primitive because only class can have methods. Primitive can not. And String need many functions to be called upon while processing like substring, indexof, equals, touppercase. What is non-primitive datatype?
