swing - How to add text to a single text field from many buttons ?? -- Java -
as can read title, need set text of jtextfield pressing buttons.. , buttons should disappear when clicked(which did method 'setvisible'), when delete letter button must appear again..
but focus on "how add text single text field many buttons".. each button when pressed must add letter,
the code did far// note : i'm working on netbeans ide
