How to convert char to string by using method invocation?

**Akirien** · August 25th, 2012, 11:20 PM

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.
