operator cannot be applied to java.lang.string int

[Lucian Cyd]

I dunno what to do. I get the following error:
operator cannot be applied to java.lang.strin g int

public void actionPerformed(ActionEvent e)
		{
			

		
		if(e.getActionCommand().equals("Celsius"))
		{
		
		
		C = JOptionPane.showInputDialog("Enter temperature here: ");
		
		a1 =Double.parseDouble(C);
			
		Can = (C *9/5) + 32;
			
			JOptionPane.showMessageDialog(null, + Can + "Fahrenheit.");
			
		}

C is a string and you are trying to multiply it with 9 and divide by 5. You can not perform arithmetic operations on Strings.

I guess it should be

Can = (al *9/5) + 32;
