In the labs11.assignment2 package, create the FileIO class with the following elements:
 A public method that reads text from the file text.txt and prints that text to the console.
 A public method that receives two strings as its input parameters, and writes them to the file text2.txt
(each string in a separate row).
 A public method that writes the following numbers: 45,56,67,78 in the file numbers.out; each number
should be written in a separate row.
 A public method that reads all numbers from the numbers.out file and prints their sum to the screen (pay
attention to the fact that each number is in a separate row).
Create the TestFileIO class in the labs11.assignment2 package. In the main method of this class, create an object
of the FileIO class and call its methods.
