    Hello All, Good day! I'm new in Java and Hopefully you can help me with my first post :)

    I have a form with text fields (txt_field1, txt_field2, txt_field3) radiobutton (rad_btn1, rad_btn2) and button (btn_save, btn_cancel)

    I just want, when the user input a data in txt_field1,txt_field2,txt_field3, choose rad_btn1 and click btn_save, it will save in a file prompting "Please enter file name to save" and then it will message "File has been successfully created".


    Is This A Good Question/Topic? 0
