Temperature conversion program

Our goal is to create a temperature conversion program, and I've set up the input portion of this program for us already:

public class TemperatureConverter { 
    public static void main(String[] args) { 
        Scanner reader = new Scanner(System.in); 
        char inputType; 
        char outputType; 
        float inputValue; 
        float returnValue; 
         
        System.out.print("Input type (F/C/K): "); 
        inputType = reader.next().charAt(0); 
        System.out.print("Output type (F/C/K): "); 
        outputType = reader.next().charAt(0); 
        System.out.print("Temperature: "); 
        inputValue = reader.nextFloat(); 
    } 
} 

So far, this program takes three pieces of information from the user. The first is the temperature type: F for Fahrenheit, C for Celsius, and K for Kelvin. Then it takes another ...
