How can we use primitive data types as objects?

Primitive types are not objects in Java , but the term ‘datatype’ isn’t restricted to the primitive types.

In JavaScript, a primitive (primitive value, primitive data type) 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.

The primitive data types are not objects so they do not belong to any class. While storing in data structures which support only objects, it is required to convert the primitive type to object first which we can do by using wrapper classes .

An object of Double is created. An object of Boolean is created. In the above example, we have created variables of primitive types ( int , double , and boolean ). Here, we have used the valueOf() method of the Wrapper class ( Integer , Double , and Boolean ) to convert the primitive types to the objects .
