Temperature converter java code

For instance, it converts C to F. It converts F to 0 C. My conversion formulas are right. Can anyone give me some clues? I tried declaring the floats in the class outside the main, but it didn't help. Stack Overflow for Teams — Collaborate and share knowledge with a private group.

Map Classes. But you're presenting your code here to get advice how to improve your programming skills, so here are a few remarks. Take them as a hint where to go from here, as soon as you feel ready for the "next level". Your main method contains both aspects in one piece of code, even within the same line e. Make it a habit to separate tasks that can be named individually into methods of their own:.

With separate methods, it will be easier to later change your program to e. Your current program always forces the user to do exactly one C-to-F and then one F-to-C conversion. This will rarely both be needed at the same time. I'd either ask the user at the beginning for the conversion he wants, or make it two different programs. By the way, doing so will be easier if the different tasks have been separated. Combine variable declaration and value assignment.

You wrote double fahrenheit, celsius; and later e. This way, when reading your program maybe half a year later , you immediately see at the same place that celsius is a double number coming from some input. Using two separate characters does the job in a more robust way. Sign up to join this community. The best answers are voted up and rise to the top.
