    Default How to convert char to string by using method invocation?

    public class MethodCall5
     
    {
     
    	public static void main(String[] args)
     
    	{
     
    		MethodCall5 f = new MethodCall5();
    		char q = f.g("Good");
     
    		System.out.println(q);
     
    	}
     
     
    	public char g(char output)
     
    	{
     
    		return output;
     
    	}
     
    }

    I received an error state that "actual argument String cannot be converted to char by method invocation conversion". How can I fix the error? Thank you..

    Hello Akirien!

    The g method's signature indicates that it takes a char parameter. But in your main method you invoke g passing it a String ("Good"). You need to pass it a char parameter to fix the error.
    If you actually want it to take a String parameter then you need to 'say' it in the g's signature.

    Hope it helps.
