Project 2<\/strong><\/p>\n

\u00a0<\/p>\n

Description:<\/h2>\n

Using GUIGreet.java<\/a> as a model, create a Java stand-alone GUI program that displays a Fahrenheit to Celsius temperature conversion table in an AWT Frame<\/code> or a swing JFrame<\/code>.\u00a0 The table should run from 0\u00a0degrees Fahrenheit to 250\u00a0degrees Fahrenheit, in steps of 10 degrees.\u00a0 Round the Celsius temperature values to the nearest integer.<\/p>\n

Display any temperatures below the freezing point of water (32o Fahrenheit) in blue and any temperatures above the boiling point of water (212o Fahrenheit) in red (the rest in black).<\/p>\n

The formula to use is:<\/p>\n

Degrees Celsius = ( 5 \u00f7 9 ) \u00d7 ( Degrees Fahrenheit – 32 Degrees )<\/p>\n

See TempConv.jar<\/a> model solution for a sample chart; just download and double-click to run.\u00a0<\/p>\n

Other Requirements:<\/h2>\n

You must turn in a stand-alone AWT or swing program, not an Applet<\/code> or JApplet<\/code> nor a JavaFx program.\u00a0 You must meet all the requirements from the description above.\u00a0 If you include any creative extras, be sure your program still performs the basic chart as described above.\u00a0 Creative extras are extras<\/em>, and you are not free to modify the project requirements.<\/p>\n

It is not acceptable<\/strong> to pre-compute each Celsius value, and just have many \u201cg.drawString()<\/code>\u201d statements.\u00a0 You need to use Java to calculate each value using the correct formula, and use various control structures.<\/p>\n
