Write a program to create a file named RandomNums.txt if it does not exist. Write 100 integers created randomly into the file using textI/O. Integers are separated by spaces in the file. Read the data back from the file and display the data in increasing order.
- Next, add a feature to the existing code that finds the number with the highest number of occurrences.
- Write your results to a file.
- Print the output to the console for verification and debugging.
- Use OOP design.
- Use exception handling as necessary.
- Use comments accordingly.
The program must be OOP in design and implement a test class. use of Collections .frequency() to pull number counts

Then ask the user for a third number and do the same. Keep asking for numbers until the person puts in a zero to terminate the program. Close the file. Be sure to use at least 2 functions [main() and total_numbers(number, total)]. Put all inputs and outputs into the main function, with all calculations into the total_numbers function.
