Implement Following Methods Properties Change Jar Class Properties Need Four Instance Vari Q43881295
In Java, 
Implement the following methods and properties in Change Jar class. For properties, you will need four instance variables: quarters (integer), dimes (integer), nickels (integer), pennies (integer). There are no dollars bills (or dollar coins) in this Change Jar. For methods, you will need to implement the following (include any setters or getters that are needed). Unless otherwise stated, you can assume the input has no errors for step 2 (i.e., a valid set of numbers) contained within (later steps this does not apply). • public ChangeJar() Default constructor that sets the Change Jar to zero. public ChangeJar (double amount) A constructor that initializes the instance variables with the provided value converted to quarters, dimes, nickels, and pennies. For example, if amount was 1.34 then you would have 5 quarters, 1 nickel, 4 pennies. Page • public Changejar (ChangeJar other) A constructor that initializes the instance variables with the other ChangeJar parameter. public ChangeJar (String amount) A constructor that accepts a string as a parameter with the provided value converted to quarters, dimes, nickels, and pennies. For example, if amount was “1.34″ then you would have 5 quarters, 1 nickel, 4 pennies. More examples: o “1.3” is 5 quarters, 1 nickel o “1.34” is 5 quarters, 1 nickel, 4 pennies O “0.34” is 34 cents; 1 quarter, 1 nickel, 4 pennies O “0.04” is 4 cents o “500.” is not allowed, instead “500.0” is used. public boolean equals (Object other) A method that returns true if “this” Change Jar object is exactly the same (in terms of the amount in the Change Jar) as the other object (Note: you must cast the other object as a Change Jar object). public static boolean equals (ChangeJar jari, ChangeJar jar2) A static method that returns true if Change Jar object jarl is exactly the same (in terms of amount in the Change Jar) as if Change Jar object jar2. public int compareTo (ChangeJar other) A method that returns 1 if “this” Change Jar object is greater than (based upon the total in the ChargeJar) the other Change Jar object; returns -1 if the “this” Change Jar object is less than the other Change Jar; returns 0 if the “this” Change Jar object is equal to the other ChangeJar object. public static int compareTo (ChangeJar jari, Change Jar jar2) A method that returns 1 if Change Jar object jarl is greater (in terms of the amount in the Change Jar) than ChangeJar object jar2; returns -1 if the Change Jar object jarl is less than Change Jar jar2; returns 0 if the Change Jar object jarl is equal to ChangeJar object jar2. public void subtract(int quarters, int dimes, int nickels, int pennies) A method that subtracts the parameters from the “this” ChangeJar object. You may assume all of the parameter are positive. public void subtract (Changejar other) A method that subtracts Change Jar other to the “this” Change Jar object. (For step 2 there are no worries about errors) public void dec (). A method that decrements the “this” ChangeJar by 1 penny. public void add (int quarters, int dimes, int nickels, int pennies) A method that adds the parameters from the “this” ChangeJar object. You may assume all of the parameter are positive. • public void add (Changejar other) A method that add ChangeJar other to the “this” Change Jar object. • public void inc() A method that increments the “this” ChangeJar by 1 penny. public String toString() Method that returns a string that represents a ChangeJar with the following format: “10 quarters, 1 dime, 0 nickels, 1 penny”. Be sure to use proper pluralization. For example, 1 penny or 2 pennies. Show transcribed image text Implement the following methods and properties in Change Jar class.
