Create a GUI in java that converts between Fahrenheit and Celcius Antemperatures. GUI should look like this: If I enter a number in the Fahr box, click F $->$ C$,$ the Centigrade is displayed. If I enter a value in Cent, the Fahrenheit is displayed when clicking C F$.$ So the boxes represent both inputs and outputs depending on the button clicked. If a box is clicked and no proper value is in the ionput box, an Error should be displayed. Do the conversion logic in a separate "business logic" class. The class called "TemperatureConversion" should just have $1$ private field. It should provide the following methods: toCentigrade$()$ toFahrenheit$()$ getValue$()$ No setters are necessary and have only one constructor. The internal field would take on different meanings depending on whether toCentigrade or toFahrenheit is called. If toCentigrade is called, then assume the internal value is in Fahrenheit. If toFanhrenheit is called, assume the value in in Centigrade. The getValue just returns the internal field.
