Question 2

Important things to note about constructors?

Answer 2

Note that the constructor name must match the class name, and it cannot have a return type (like void).

All classes have constructors by default: if you do not create a class constructor yourself, Java creates one for you. However, then you are not able to set initial values for object attributes.
