     Put a

     System.out.println(arg0.getActionCommand());-

     in your method, and supposedly you will see that it is not "C" when using the Celsius button.

     Generally, look at the console to see if there are any error messages around.

     Another idea: You are using two double variables temps and temp1, parsing the instrings into both of them, and setting then one of them to the result. Why so complicated?

     In general, I would recommend to not use the getActionCommand() method, but to give each button an own ActionListener. You can use an anonymous class for this. As both cases do almost the same, use two subclasses of a inner (or even local) class here:

     abstract class ConversionListener implement ActionListener { DecimalFormat formatter = new DecimalFormat("#,###,###.##");- public void actionPerformed(ActionEvent e) { String input = temp.getText(); if (input.equals("")) { input = "0"; temp.setText(input); } double number = Double.parseDouble(input); results.setText(formatter.format(convert(number))); } /** to implement by subclasses */ abstract double convert(double number);}celsiusToFahrenheit.addActionListener(new ConversionListener() { double convert(double celsius) { return number * 9 / 5 + 32; }});fahrenheitToCelsius.addActionListener(new ConversionListener() { double convert(double fahrenheit) { return (fahrenheit - 32) / 9 * 5; }});-

     Do it as follows:

     public void actionPerformed(ActionEvent ae) { double t = Double.parseDouble(tfInput.getText().trim()); Object source = ae.getSource(); // test for exit button if (source == jbExit) { System.exit(0); } else if (source == jbC2F) { tfOutput.setText(String.valueOf(t * 9.0 / 5.0 + 32.0)); } else if (source == jbF2C) { tfOutput.setText(String.valueOf((t - 32.0) * 5.0 / 9.0)); }}

     Here's a solution that doesn't use type casting. 9/5 in the first method is integer division, resulting in

     -40 * 1 + 32 = 8

     Rewrite the return expression as (temp * 9 / 5 ) + 32 (remove the parentheses around 9/5. This will force temp * 9 first and then division by 5 after.

   • Celsius to Fahnrenheit and Fahrenheit to Celsius using 3 methods

     float output = ftoC(input); // I'm kind of confused as to why she told me to put the variable inside of the (); -

     This is so you can pass the variable to the function ftoC.

     System.out.println(ftoC(input)); //Same here with the variables :(-

     Same as above. How else will the data get to the function or method?

     public static float ftoC(float f) //This is a method line, but why is float f inside the parenthesis?

     Because you have to tell the program what your data type is so it knows how to lay it out in memory. Otherwise, it has no idea how big you want your data type to be in memory. Also, if you were to pass an int to a method that expects float, the program would exhibit different behavior.

   How to convert Celsius temperature to Fahrenheit?

   • To convert a Celsius temperature to Fahrenheit or vice versa, it is not necessary to store the temperature value. Rather, a conversion method could take the Celsius (or Fahrenheit) temperature as a parameter, perform the conversion, and return the result. Therefore, the Temperature class does not need any instance variables.

   The methods will use the standard conversion formulas: F = 9/5 C + 32 and C = 5/9 (F - 32). Each of these methods should have a single parameter to store the temperature value that is being converted. Because we want to be able to handle temperatures such as 98.6, we should use real-number data for the methods' parameters.
