You are getting that error because the class Control doesn't have a 
method named setText. You probably want to declare controls as follows:

private Text[char[]] controls; // Use associative array

(and probably use another name instead of controls)

 
 I play with and put in 
 
 }
 
   void setText(char[] text)
 { 
   setText(text);//dont understand why this does not cause infinite loop?
 }

When you defined that method, did you invoke it? If not, that's why you 
didn't get infinite loops. But you should, if you invoke it.

 
   void setText(char[] name, char[]text)
   {
 //   name.setText(text);
   }
 }
 
 with layout in shell above compiles and runs giving 9 text boxes with right
text.
 
 Question   When setText(name,text ) is called Why does setText(text) not cause
infinit loop?

That's a different question. setText(name, text) and setText(text) are 
different methods: two methods are considered the same if they have the 
same name, same formal arguments, and same return type.

 It calls itself seems so
 I tried to put in 'override' but would not compile

Because setText(char[] name, char[] text) is not a method of Object (the 
class your Box is inheriting from). It wouldn't work either if you 
extended from Text, because Text has the method setText(char[] text), 
which is a different method than setText(char[] name, char[] text).

Ok file posted too but did not show only pasted contents direct here.

setText(name text)  calls (invokes) setText(text) which is method of Text. Box
creates many Text objects , each has a setText(text) method .

Notice setText(text) calls itself ?

Aah... I didn't know it was Ty Tower. But maybe you are right because of 
the extra spaces before dots and commas...

Whether you are Ty Tower or not, I'd recommend you to read some OOP book
