in here can specify path , file name. want same thing "save png" button. have no idea how that. can please help? in advance.

you can use jfilechooser 

                string suggesteddir = ".";             string extension = ".png";             jfilechooser filechooser = new jfilechooser(suggesteddir);             jframe choose = new jframe();             choose.settitle("save ...");              int status = filechooser.showsavedialog(choose);             if (status == jfilechooser.approve_option)              {                  try                  {                     file selectedfile = filechooser.getselectedfile();                     string newfile = selectedfile.getcanonicalpath();                     if (!newfile.endswith(extension)) {                         newfile=newfile + extension;                     }                      imageio.write(img, "png", new file(newfile)); //write img file                  } catch (ioexception ex) {                     ex.printstacktrace();                  }             }
