Test 1

This grade will be calculated as 25% of the lecture test 1.

You are permitted the use of pre-written notes, previous labs and the textbook. You

are NOT permitted the help of the Lab TA or the Internet. Any cheating will result

in a report Academic Integrity Violation and an ‘F’ in the course.

Document your code with inline comments and javadoc comments. This is a majot

portion of your grade.

Read this entire document before starting to write code.

Write and test a Java project that satisfies the following requirements:

Create a measurement converter project that can convert between grams, ounces, pounds

and kilograms.

The constants for conversion are:

        1 ounce = 28.35 grams

       16 ounces = 1 pound

        1 kg = 1000 grams

Write a class definition file named WeightConverter that has these fields:

weightInOunces

weightInPounds

weightInGrams

weightInKiloGrams

The class also needs the three constant fields for the conversions as listed above.

Write the following methods:

Two constructor methods:

The default constructor sets all the field values to zero except the constant. The constant

is set using the conversion given above.

The overloaded constructor accepts a value for the weight of an item in pounds and

calculates the values for the remaining three fields.

Write four set( ) methods that allows the user to change any measure (setOunces,

setPounds, setGrams, setKiloGrams) The set methods must ensure all the fields are

consistent.

Write four get( ) methods. One get method for each of the four fields (not including the

constants.

Write a driver class that has the main( ) method.  This main method should provide the

following utility:

Create an instance of the WeightConverter class using the default values.

Write a loop that allows the user to reset any of the measures. Ask the user to enter which

measure to change, read in the value and call the appropriate set method. Then print the

value of each of the four fields. This process continues until the user indicates he/she

wants to quit.  

Once the loop exits, print a Goodbye message.

You will be graded on:

The code must compile.

The code must be well documented. Document each method and use the conventions for

naming fields, constants, local variables, constants and class names as well as javadoc

comments.

The code must give correct results in the output.

When done:

• Submit the two .java source code files to Moodle. Be sure your submissions have

been uploaded correctly. This is your responsibility.

• Give this requirements sheet back to your Lab TA. If you do not give the sheet back

you will earn a zero on this test.

• Shut down the computer.
