Connecting view button to player! help

Question

hi! I have posted my codes for Client and ClientChoice.
in the actionlistener event of the ClientChoice(gui) have i have called the Client class where the player is found and where connection is made to the server. the error i get is that the .class of the Client is:
mainCl(java.lang.String[]) in Client cannot be applied to (java.lang.String,java.lang.String)          cl.mainCl(a,b);
can anyone help me ! am i doing the right thing or someway else plz help me......i have a week on that and i'm being late. here are the code:

Answer 1

You are passing two String objects to a method that accepts an String array.
try this to get rid of one error.
Client cl = new Client(a, b);
String[] c = {a,b};
Client.mainCl(c);
