N.B. Parking office methods in the class definition like register, getcustomer and addcharge have already been implemented, we just need an additional getPermitIds(Customer) method as mentioned above Explain your code in a few words Important- We have a method to return a collection of permit ids (getPermitIds), what we need is a method to return the collection of permit ids for a specific customer (getPermitIds(Customer))Write a Java program with least two classes.

The method isSolvable() willbe called in the main, if it returns true display the calculated values for x and y by calling getX()and getY(). If the call to isSolvable() returns false, display a message that “the equation has nosolution”. Write a Java program that prompts the user to enter a, b, c, d, e, and f and displays the result. After the valuesfor a through f are entered, create a LinearEquation object. Check to seeIf ad - bc is 0, report that “The equation has no solution”, otherwise print out the values for x and y.Create a Java project that shows the benefits of using generic types besides the examples from the activity.

Group of answer choices 1. None of the above options are correct. 2. Comparable is an interface, while comparators is an abstract class. 3. Implementing Comparable allows the implementing class to compare instances of itself to other objects, while the Comparator interface is implemented by an auxiliary class that compares two objects of a given type. 4. Comparable guarantees that you can check for equality, while Comparator guarantees that you can order the items.Implement all the classes using Java programming language from the given UML Class diagram. Note: This problem requires you to submit just two classes: Person.java, User.java, Coach.java. Do NOT include "public static void main()" method inside all of these classes.
