penjelasan dari source code diatas: program diatas dimulai dengan dengan membuat nama kelas yaitu class login selanjutnya mendesain jframe untuk menu login pertama kali, nah jframe nya nanti dibuat berisi nama pengguna dan kata sandi anda dapat mendesain jframe nya sesuai keinginan anda dengan fitur pallete setelah itu selanjutnya anda mengedit nya dengan klik kanan lalu edit text dan setalah itu klik kanan selanjutnya kita memasukkan program untuk jframe tadi program diatas memakai array untuk menyimpan data nama pengguna dan kata sandi atau password, nama pengguna dan password disini dapat anda atur sendiri sesuka hati anda contoh nya saya membuat nama pengguna: yohana dan kata sandi: 2002, perhatikan dengan teliti penggunaan huruf kapital atau tidak yang anda pakai karna itu sangat berpengaruh. nah selanjutnya saya akan menjelaskan source code untuk jframe nya ada dua text box yaitu masuk dan keluar didalam texst box masuk dimasukkan kodingan sebagaimaana contoh source code diatas selanjutnya text box keluar juga dimasukkan source code seperti diatas jika anda menekan text box keluar maka akan muncul dialog box "apakah anda yakin keluar?" (gambar akan saya tampilkan dibawah) selanjutnya jika anda menekan text box masuk maka anda akan langsung terganti ke menu jframe beranda lalu akan muncul selamat datang yohana.
berikut adalah hasil dari program diatas:
sekian penjelasan program diatas, jika ada penjelasan yang kurang dimengerti saya mohon maaf terimakasih;) (btw warna teksnya emang biru hehe)
