Implement the class Vaccine so that it contains: ✓ 3 private instance variables: name of type String, doses of type integer which records the number of doses taken, and isAuthorized which is Boolean and indicates if the vaccine is proven safe or not. ✓ A default constructor which sets the numeric instance variable to zero and the String instance variable to null. ✓ A constructor with 3 parameters which sets the 3 instance variables to the corresponding values passed. ✓ Implement an accessor method for each of the 3 instance variables that will return the value of the instance variable. For example, the getX() method for the instance variable name must be called getName(). Implement a mutator method for each instance variable that will assign to the instance variable the value passed. For example, the setX() method for the instance variable type must be called setName(). ✓ An equals method: two objects of type Vaccine are equal if all the attributes of both objects have the same values. ✓ A Boolean method bothAuthorized which returns true if both vaccines are Authorized and false otherwise. ✓ A toString function must also be provided to return the vaccine information in the following format: The Vaccine of name <name> has <doses> dose(s) and is Authorized is <isAuthorized> Where <name>, <doses> and <isAuthorized> are the contents of the instance variables. If you correctly implemented all the above, running the main method will result in your program displaying exactly as in the boxes below. Your program should work for any values entered. REMEMBER in the output: is a space, → is a tab and J is a new line. Text in green is user input. The only formatting you are concerned with is the one generated by the toString method (in blue) the rest is already set in the main method which you are not to change.
