Define a class with following specifications.
Class Name: JoinArray
Member Variables:
size – To store the number of elements.
ar[] – Array to store elements/numbers.
Member Methods:
JoinArray(int n) – Parameterized constructor to initialize member variables.
void getElements() – Accept the elements/numbers using Scanner class.
void doJoin(JoinArray A,JoinArray B) –
To join two arrays into one array.
void displayArray() –
To print the new joined array.
Invoke all the above methods in main() function using object of the class.
