I have a 3 part problem for my computer science class that I am completely lost on.

This is the first part:

• Write a Temperature class that has two instance variables: a temperature value (a floating-point number) and a character for the scale, either C for Celsius or F for Fahrenheit. The class should have four constructor methods: one for each instance variable (assume zero degrees if no value is specified and Celsius if no scale is specified), one with two parameters for the two instance variables, and a no-argument constructor (set to zero degrees Celsius).

  Include the following: (1) two accessor methods to return the temperature-one to return the degrees Celsius, the other to return the degrees Fahrenheit-use the following formulas to write the two methods, and round to the nearest tenth of a degree:

  DegreesC = 5(degreesF - 32)/9 DegreesF = (9(degreesC)/5) + 32; 

  (2) three mutator methods: one to set the value, one to set the scale (F or C), and one to set both; and (4) a suitable toString method. Then write a driver program (or programs) that tests all the methods. Be sure to use each of the constructors, and to test at least the following temperature equalities: 0.0 degrees C = 32.0 degrees F, -40.0 degrees C = -40.0 degrees F, and 100.0 degrees C = 212.0 degrees F.

This is the second part of the question:

• In that Temperature assignment, you have implemented two formulas to convert between Celsius and Fahrenheit. Now, you will implement your solution in Java Swing.
• You are free to design any meaning GUI interface.
• You have to use JTextField as input and it only received valid double as input -- provide very simple Exception Handling. You are free to design what to do with invalid input.

This is the third part to the question

• Reorganize
  1. Temperature conversion in /model folder
  2. UI in /view folder
  3. Driver.java to start the program
• Additionally
  1. Temperature conversion as static method
  2. Use only inner classes for JButton Actions (no more ActionListener)
  3. Use metal look and feel
