In java Se8 i am trying to write a program convert temperature between celsius, fahrenheit and kelvin, but i am stuck at how to return the proper result without chage the frame, and I cnould not figure out how to use those three settemp method.

Answer 1

t.setTemp (10.1, "Kelvin"); System. out.println (t.getTemp ()"K")//283.25 System.out.println ("10.1K"); t. setScale ("E"); t.setTemp (10.1, 'F); System. out.println (t)//50.18F System.out.println ("10.1F") t. setScale ("K"); t.setTemp (10.1, 'K'); System. out.println (t)//50.18F System.out.println("10.1K") Sample Output: D: \Program Files\Java\jdkl.8.0_40\bin>javac Temperature.java D:\Program Files\ Java\jdkl.8.0_40\bin>java Temperature 10.1C 50.18F 10.1F 283.1K 10.1K 50.18F 10.1F 283.11K 10.1K D:\Program Files\Java\jdkl.8.0_40\bin>
