I have 3 classes in java (Movie class, Rental class and Customer class) Please write a test class in java to test these classes. Thanks

********************

import java.util.* ;

public class Movie {

public static final int CHILDRENS = 2; public static final int REGULAR = 0; public static final int NEW_RELEASE = 1;

private String _title; private int _priceCode;

public Movie(String title, int priceCode) { _title = title; _priceCode = priceCode; }

public int getPriceCode() { return _priceCode; }

public void setPriceCode (int arg) { _priceCode = arg; }

public String getTitle() { return _title; } }

***************************************

public class Rental {

private Movie _movie; private int _daysRented;

public Rental(Movie movie, int daysRented) { _movie = movie; _daysRented = daysRented; }
