Is an array list a primitive data type?

ArrayList accepts only reference types as its element, not primitive datatypes.

What is one difference between a primitive data type and a class data type?

A primitive is a data type which is not an object. int , float , double , long , short , boolean and char are examples of primitive data types. You can’t invoke methods on these data types and they don’t have a high memory footprint, which is their striking difference from classes.

Why array is not a primitive data type?

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.

Can array lists hold different data types?

The ArrayList class implements a growable array of objects. ArrayLists cannot hold primitive data types such as int, double, char, and long (they can hold String since String is an object, and wrapper class objects (Double, Integer). Like an array, it contains components that can be accessed using an integer index.

What is the difference between primitive and complex data types?

The primitive data types are types like string , integer , boolean , etc. that can take a single value. The complex types consist of multiple values grouped together.

What is difference between primitive and composite data type?

If two variables contain data that is primitive they compare by value. This means that if they both contain the same values they are equal. If two variables contain data that is composite they compare by reference. This means that they can only be equal if they refer to the same object.

What are primitive data types and give two examples?

Primitive data types are the basic or fundamental data types used to declare a variable. Examples of primitive data types in Java are byte, short, int, long, float, double, char, boolean.

What is a primitive array?

Arrays of primitives have elements that are initialized to default values. Arrays of objects have the value null in each element.

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. Non-primitive types are created by the programmer and is not defined by Java (except for String ).
