Create a directory for this exercise. In that directory, create a file named Weight.java. In this file, create a class named Weight, containing a program that converts a weight in kilograms into the equivalent weight in old-fashioned Imperial units of pounds and ounces.

Your program should allow the weight in kilograms to be input by the user as a floating-point value, and it should represent this value internally using the double type. It should convert this value into numbers of pounds and ounces, using an int variable to represent the number of pounds and a double variable to represent the number of ounces. The program should display the converted weight in a single line of output. The number of ounces should be displayed with 1 decimal place of accuracy.

Here is an example of what the user should see when running the program from a terminal window:

$ java Weight
Enter weight in kilograms: 1.8
Equivalent imperial weight is 3 lb 15.5 oz

Note that the output uses the standard abbreviations for pounds and ounces: ’lb’ and ‘oz’.

Tips

• Use the Scanner class to handle input of the weight in kg – see Section 2.4.6 of Eck’s book or the API documentation for examples.

• Use a single call to System.out.printf() to output the result. Remember that this works in a similar way to C’s printf() function.

• Follow a two-step approach, in which the weight is converted first into a total number of ounces. You can easily google the required conversion formula for this. The second step is to break down the total number of ounces into a whole number of pounds and the remaining number of ounces, noting that there are 16 ounces in a pound. You’ll find the % operator useful here.
