What is the difference between primitive and non-primitive data types?
The main difference between primitive and non-primitive data types are: Primitive types are predefined (already defined) in Java. A primitive type always has a value, while non-primitive types can be null. A primitive type begins with a lowercase letter, while non-primitive types begin with an uppercase letter.

What are non-primitive data types in JS?
JavaScript non-primitive data types
Type of data | Description |
---|---|
Object | represents an instance through which we can access the members |
Training | represents a group of similar values |
RegExp | represents the regular expression |
What is the difference between primitive type and composite data type?
Differences between primitive data types and composite data types. If two variables contain data that is primitive, they are compared by value. This means that if they both contain the same values, they are equal. If two variables contain composite data, they are compared by reference.
What is the difference between JavaScript primitives and objects in the context of how they are stored in memory?
The primitive value is stored directly in the location accessed by the variable. Reference values are objects that are stored on the heap. The reference value stored in the variable location is a pointer to a location in memory where the object is stored.
What are 4 examples of non-primitive data types?
1. Class, object, array, string, and interface are called non-primitive data types in Java. These data types are not predefined in Java. They are created by programmers.
What are non-primitive data types?
Non-primitive data types: these data types are not really defined by the programming language, but are created by the programmer… They are the following:
- boolean data type.
- byte data type.
- char data type.
- short data type.
- int data type
- long data type.
- float data type.
- double data type.
What is a non-primitive data type?
Non-primitive data types are created by the programmer and are not predefined. Since non-primitives are called objects, they can be assigned a null value, which is not a case in the primitive type. Unlike primitive data types, a non-primitive data type must begin with an uppercase letter.
What is non-primitive value?
The data types that are known as primitive values in JavaScript are Number, String, Boolean, Null, Undefined. Objects like functions and arrays are known as non-primitive values. The fundamental difference between primitives and non-primitives is that primitives are immutable and non-primitives are mutable.
What do you mean by primitive data types?
A primitive data type is a data type built into a programming language or one that could be characterized as a basic structure for creating more sophisticated data types.
What is the difference between primitive data type and object?
Let’s see the difference between the primitive data type and the object type in tabular form… Java.
Properties | Primitive data types | Objects |
---|---|---|
when copied | Two different variables are created along with a different assignment (only the values are the same) | Two reference variables are created, but both point to the same object on the heap |
What are the three primitive data types in JavaScript?
In JavaScript, a primitive (value primitive, data type primitive) is data that is not an object and has no methods. There are 7 primitive data types: string, number, bigint, boolean, undefined, symbol, and null.
