A Weight.java class that has three private variables, two private methods, and four public methods, and a Project.java class that has three private methods. The goal of this assignment is to perform calculations using
Weight objects (instances of Weight class).
Weight Class
Weight class should have three private variables, two private methods, and four public methods.
Variables
Hint: How should/can you access these private variables?
1. A private constant variable called OUNCES_IN_A_POUND defines the number of
ounces in a pound (16).
2. A private variable called pounds with a data type of integer.
3. A private variable called ounces with a data type of double.
Methods
1. A public parameterized constructor, which initializes the private variables.
public Weight (int pounds, double ounces){
// implementation
}
2. A private instance method called toOunces with a return type of double. This method
has no parameters and should return the total number of ounces. For full credit, reuse this method
across other methods when possible.
3. A private instance method called normalize with a return type of void. This method has
no parameters and should ensure that the number of ounces is less than the number of ounces in a
pound. For full credit, reuse this method across other methods when possible.
4. A public instance method called lessThan with a return type of boolean. This method
should accept a Weight object as a parameter and determine if the object is greater or less than
the initialized values.
public boolean lessThan (Weight weight){
// implementation
}
5. A public instance method called addTo with a return type of void. This method should
accept a Weight object as a parameter and add the object's weight values to the initialized
values.
public void addTo (Weight weight){
// implementation
}
6. A public instance method called toString with a return type of String. This method has
no parameters and should have the following format:
x pounds and y ounces
where x is the number of pounds and y is the number of ounces. Ounces should be
displayed with two decimal places.
Project1 Class
Project1 class should have three private methods and one public method.
Methods
1. A private class method named findMinimum with a return type of Weight. This method
should accept three Weight objects as parameters and compare each Weight object's
weight values to find the minimum. The Weight object with the minimum weight value
should be returned and then printed using toString in the following format:
The minimum weight is x pounds and y ounces
where x is the number of pounds and y the number of ounces. Ounces should be
displayed with two decimal places.
2. A private class method named findMaximum with a return type of Weight. This method
should accept three Weight objects as parameters and compare each Weight object's weight
values to find the maximum. The Weight object with the maximum weight value should be
returned and then printed using toString in the following format:
The maximum weight is x pounds and y ounces
where x is the number of pounds and y the number of ounces. Ounces should be
displayed with two decimal places.

3. A private class method named findAverage with a return type of Weight. This method
should accept three Weight objects as parameters and calculate the average weight value. A new
Weight object with the average weight values should be returned and then printed using toString
in the following format:
The average weight is x pounds and y ounces
where x is the number of pounds and y the number of ounces. Ounces should be
displayed with two decimal places.

 

4. A public method named main with a return type of void. This method should exercise the
correct functionality of findMinimum, findMaximum and findAverage by creating three
Weight objects using the hardcoded values below:
Weight weight1 = new Weight(11, 3);
Weight weight2 = new Weight(7, 20); // Hint: normalize method should be
used to translate into 8 pounds and 4 ounces
Weight weight3 = new Weight(14, 6);
