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

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 ?

 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)

   void setText(char[] text)

   setText(text);//dont understand why this does not cause infinite loop?
 }

didn't get infinite loops. But you should, if you invoke it.
   void setText(char[] name, char[]text)
   {
 //   name.setText(text);
   }
 }

 Question   When setText(name,text ) is called Why does setText(text) not cause

different methods: two methods are considered the same if they have the same name, same formal arguments, and same return type.

Could you please point where in the pasted code is that call? I can't see it. I can see it, thought, separated from the rest of the code (after you wrote "I play with and put in"). Can you paste the modified main method, then?

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 or tutorial.
