Create a Java class named Person with a constructor, utilizing getter and setter methods to manage its attributes. Define a class Person with attributes name $($a String$),$ age $($an int$),$ and email $($a String$).$ Implement getter and setter methods for each attribute to encapsulate the data. Write a method named displayInfo that prints the details of the person in a formatted manner. In a separate class PersonTest, write a main method to instantiate at least two Person objects. Use the setter methods to set the values of the attributes for each object, then call their displayInfo methods to demonstrate their functionality. Be sure to include comments in your code to explain your implementation, and follow Java best practices for naming and formatting.
