Write a Java class that implements the concept of Coins, assuming the following attributes (variables): number of quarters, number of dimes, number of nickels, and number of pennies. Include two constructors (non-argument constructor that assigns 1 to each coin, and another constructor that takes necessary arguments to create an object), needed getter and setter methods, method toString (to print coins objects in a meaningful way), and method equals (to compare two coins objects based on number of coins). Also include the following methods:

- (4 pts) A method to return the amount of money in dollars notation (e.g., $0.41 if you have one coin of each)

- (1 pt) Write a test program (client class) to test all methods in the class.
