public final static void main(String args []) {

// 1. Add comments that describes the class, along with each attribute and operation.

// 2. Add appropriate 'private' and 'public' modifiers to each of the attributes and methods.

// 3. Within this main method, create a new instance of the Logger class (called 'log')

// 4. Call each of the available methods several times on the 'log' instance.

// 5. Add a method called displayLog(), that outputs all of the messages stored within the log. hint: use a for loop.

// 6. Add a method called displayStats(), that outputs information about how many errors, warnings and information messages are stored.

// 7. Add code to this main methods that calls the newly added methods and shows that they work as expected.
