Explanation

In the above program, we created a module Module1 that contains the Main() function. The Main() function is the entry point for the program.

In the Main() function, We created an array list that contains mixed elements that may be integer or string. Here we used the OfType operator to find out the string elements from the array list and then print them on the console screen.
