Problem Statement: Write a JAVA program that reads a file named "input.txt" that contains integers separated by whitespace (space, tab, or newline). The program should calculate the sum of all the integers in the file, ignoring any non-numeric values.

Requirements:

The program should define a class named "FileSumCalculator".

The class should have a method named "calculateSum" that takes a file path as a parameter and returns the sum of all the integers in the file. The method should handle any exceptions that might occur during the file reading and sum calculation.

The program should print the sum of all the integers in the file to the console.

Examples:

If the contents of the "input.txt" file are:

1 2 3

4

five

6 7

The program should print:

Sum: 23
