Question

A class Mixer has been defined to merge two sorted integer arrays in ascending order.
Some of the members of the class are given below:
Classname:Mixer
Data members/instance variables:
int arr[ ]:to store the elements of an array
int n:to store the size of the array
Member functions:
Mixer(int nn):constructor to assign n=nn
void accept():to accept the elements of the array in ascending order without any duplicates
Mixer mix(Mixer A) : to merge the current object array elements with the parameterized array elements and return the resultant object
void display():to display the elements of the array

Specify the class Mixer, giving details of the constructor(int), void accept( ), Mixer mix(Mixer) and void display() . Define the main() function to create an object and call the function accordingly to enable the task.

        int sizeOfSecondArray=sc1.nextInt();
        Mixer Q=new Mixer(sizeOfSecondArray);
        Q.accept();

        Mixer R=P.mix(Q);
        R.display();
