Electrons are negatively charged, protons are positively charged, and neutrons have no charge. In an object oriented programming language of your choice, write a definition for an atom class that contains: fields for storing the numbers of protons, neutrons and electrons with appropriate visibility; setter and getter methods for manipulating these fields, ensuring that the minimum value for electrons and protons is 1, and the minimum value for neutrons is 0; a constructor that initializes new objects of atom to be the smallest element (Hydrogen), for which the number of protons is 1, the number of neutrons is 0, and the number of electrons is 1.

In addition, the class should have the following constructor and other methods: Constructor: The constructor should accept the car’s year >model and make as parameters. These values should be assigned to the object’s yearand make fields. The constructor should also assign 0 to the speed field. Accessors: design appropriate accessor methods to get the values stored in an object’s year, make, and speed fields. accelerate: the accelerate method should add 5 to the speed field each time it is called. brake: the brake method should subtract 5 from the speed field each time it is called.
