I want a TextField to display a value of char variable. But it look like I must to move that value to string variable first. And a secont thing I don't know how to make a TextField to display a value of variable, not just a named text in the quotation-marks. When I try to discribe my TextField in one place, the variable is unknown. In another place I can't add the TextField to container. In line "add(tf);) an "add" gets marked red :(

Should read APIs along with work ...

>>>>But it look like I must to move that value to string variable first

setText method takes only String. so u are correct.Conver the char to String.(not too difficult...isnt it...Goood boy :-) )
http://java.sun.com/j2se/1.3/docs/api/java/awt/TextField.html#setText(java.lang.String)

>>>And a secont thing I don't know how to make a TextField to display a value of variable, not just a named text in the quotation-marks

What u are doing and what u want to do?? a code snippet might help us to understand...

and check where u are declaring ur textfield and where u are adding it to container.

Like in init() method (just for example)

if u have

TextField tf = new TextField();

Then use...

ur container.add(tf); will work in init method only.
