The error message is this: it is not possible to find the symbol symbol: gettext method () location: txttela variable of type Jtextfield There are several errors, but it is the same. What I understand is that the gettext () and settext () method is missing in the jtextfield txttela variable, but I’m not able to do it, someone can answer for genteleza.
The error message is this:
cannot find symbol symbol: methodgettext() location: variable txttela of type jtextfield
the code is this:
