LAPORAN MEMBUAT LOGIN, KALKULATOR,SERTA GAME PADA NETBEANS

erikut adalah cara-cara membuat login pada netbeans versi8.2

A.Membuat login

1.. Buka Aplikasi Netbeans

Pertama, buka terlebih dahulu Netbeans anda.

2. Buat Project Baru

Buat project baru, kemudian pilih Java > Java Application lalu simpan. Setelah itu, beri nama Project anda tersebut.

3. Buat Class Koneksi

Buatlah Class untuk mengkoneksikan program anda tersebut dengan database MySql. Berikut sintaks defaultnya :

4. Buat Desain Form Login

Buatlah desain form Login pada umumnya dan sesuaikan dengan field database tadi. Buat 2 kolom untuk username dan password serta satu button login nya.

Kolom username buat saja menggunakan jTextField.

Kolom Password buat saja dengan jPasswordField agar password yang di ketikkan tidak terlihat.

Tombol login dengan JButton.

5. Buat Codenya

Buat code di tombol Login yang telah anda buat tadi. Caranya, klik dua kali tombol/button Login, kemudian letakkan code di situ. Anda juga bisa Klik kanan pada button Login > Events > Action > ActionPerformed.

Letakkan Sintaks untuk Login berikut :

// Tombol Login

String user = jTextField1.getText();

String password = jPasswordField1.getText();

String cekuser = null;

String cekpassword = null;

try {

Connection Connect = Koneksi.getKoneksi();

Statement st = (Statement) Connect.createStatement();

String query = "SELECT * FROM akun WHERE username = '"+user+"' AND password = '"+password+"'";

ResultSet rs = st.executeQuery(query);

while(rs.next()){

cekuser = rs.getString("username");

cekpassword = rs.getString("password");

}

rs.close();

st.close();

} catch (SQLException e){

System.out.print("Terjadi Error");

}

if(cekuser == null && cekpassword== null){

String pesan = "Username Atau Password Salah";

JOptionPane.showMessageDialog(null,pesan,"Message",

JOptionPane.INFORMATION_MESSAGE);

} else {

String pesan1 = "Login Berhasil";

JOptionPane.showMessageDialog(null,pesan1,"Message",

JOptionPane.INFORMATION_MESSAGE);

new Home() .setVisible(true);

dispose();

}

5. Save Lalu Jalankan Programnya

Sebelum menjalankan programnya, masukkan secara manual Username dan Password terlebih dahulu di tabel database yang telah dibuat tadi. isikan bebas saja, kemudian save.

Jika sudah, klik kanan file anda dan Run File.

dan hasil akhir nya akan seperti ini:

Download file

B.Membuat kalkulator

Untuk membuat kalkulator ikuti langkah-langkah berikut

Buka aplikasi Netbeans

Pilih menu file – new project

Pilih kategori java – java application

Masukan nama project, misalnya : KalkulatorGUI

Klik next maka project berhasil dibuat.

Selanjutnya pada project tersebut, klik kanan pilih new

Kemudian masukan nama class lalu klik finish.

Gambar diatas merupakan antar muka aplikasi menggunakan Jframe Form. Selanjutnya kita memilih beberapa komponen SWING untuk di drag kedalam layout aplikasi.

Komponen yang kita gunakan adalah label, button, text field dan combo box. label berfungsi untuk memberi keterangan/petunjuk pada isian form, text field sebagai form isian dan button sebagai tombol untuk memproses nilai yang dimasukan pada text field, nantinya pada komponen button kita menambahkan event actionPerformed sebagai reaksi yang dilakukan saat pengguna mengklik button tersebut.

Selain itu juga kita menggunakan combobox untuk pemilihan operasi yang ingin dikerjakan baik perkalian, pembagian, penjmlahan ataupun pengurangan. Kalian juga bisa memodifikasi dengan menambahkan operasi lainnya seperti modulus (sisa pembagian) dan eksponen (perpangkatan).

Tahap berikut kita mengatur tata letak dan desain pada aplikasinya, Secara sederhana saya membuat desain seperti berikut:

dan untuk kode nya:

Tambahkan code berikut di dalam fungsi tersebut.

if (operasi.getSelectedItem().toString().equalsIgnoreCase("Perkalian")){

int a=Integer.parseInt(bil1.getText());

int b=Integer.parseInt(bil2.getText());

int jumlah=a*b;

hasil.setText (Integer.toString (jumlah));

}

if (operasi.getSelectedItem().toString().equalsIgnoreCase("Pembagian")){

int a=Integer.parseInt(bil1.getText());

int b=Integer.parseInt(bil2.getText());

int jumlah=a/b;

hasil.setText (Integer.toString (jumlah));

}

if (operasi.getSelectedItem().toString().equalsIgnoreCase("Penjumlahan")){

int a=Integer.parseInt(bil1.getText());

int b=Integer.parseInt(bil2.getText());

int jumlah=a+b;

hasil.setText (Integer.toString (jumlah));

}

if (operasi.getSelectedItem().toString().equalsIgnoreCase("Pengurangan")){

int a=Integer.parseInt(bil1.getText());

int b=Integer.parseInt(bil2.getText());

int jumlah=a-b;

hasil.setText (Integer.toString (jumlah));

}

Dan hasil akhir nya adalah:

Download file

c.Membuat game pada netbeans

untuk membuat game langkah pertama adalah membuat project baru

Setelah itu masuk ke tampilan baru dan klik new package pada projects

Lalu buat class baru dengan cara klik new pada projects terbaru tadi lalu klik java class

Komponen yang kita gunakan adalah label, button, text field dan combo box. label berfungsi untuk memberi keterangan/petunjuk pada isian form, text field sebagai form isian dan button sebagai tombol untuk memproses hasil yang dimasukan pada text field, nantinya pada komponen button kita menambahkan event actionPerformed sebagai reaksi yang dilakukan saat pengguna mengklik button tersebut.

Atur kotak nya sesuai dengan keinginan dan saya membuat nya seperti ini:

Dan untuk coding nya:

TUTORIAL MEMBUAT LOGIN ,KALKULATOR, GAME

Berikut adalah cara-cara membuat login pada netbeans versi8.2

A.Membuat login

1.. Buka Aplikasi Netbeans

Pertama, buka terlebih dahulu Netbeans anda.

2. Buat Project Baru

Buat project baru, kemudian pilih Java > Java Application lalu simpan. Setelah itu, beri nama Project anda tersebut.

3. Buat Class Koneksi

Buatlah Class untuk mengkoneksikan program anda tersebut dengan database MySql. Berikut sintaks defaultnya :

public class Koneksi {

private static Connection Connect;

public static Connection getKoneksi(){

if(Connect == null){

try{

String url = "jdbc:mysql://localhost:3306/user";

String username = "root";

String password = "";

DriverManager.registerDriver(new com.mysql.jdbc.Driver());

Connect = DriverManager.getConnection(url, username,password);

System.out.println("Koneksi Berhasil");

}catch(SQLException e){

System.out.println("Koneksi Gagal");

}

} return Connect;

}

4. Buat Desain Form Login

Buatlah desain form Login pada umumnya dan sesuaikan dengan field database tadi. Buat 2 kolom untuk username dan password serta satu button login nya.

Kolom username buat saja menggunakan jTextField.

Kolom Password buat saja dengan jPasswordField agar password yang di ketikkan tidak terlihat.

Tombol login dengan JButton.

5. Buat Codenya

Letakkan Sintaks untuk Login berikut :

// Tombol Login

String user = jTextField1.getText();

String password = jPasswordField1.getText();

String cekuser = null;

String cekpassword = null;

try {

Connection Connect = Koneksi.getKoneksi();

Statement st = (Statement) Connect.createStatement();

String query = "SELECT * FROM akun WHERE username = '"+user+"' AND password = '"+password+"'";

ResultSet rs = st.executeQuery(query);

while(rs.next()){

cekuser = rs.getString("username");

cekpassword = rs.getString("password");

}

rs.close();

st.close();

} catch (SQLException e){

System.out.print("Terjadi Error");

}

if(cekuser == null && cekpassword== null){

String pesan = "Username Atau Password Salah";

JOptionPane.showMessageDialog(null,pesan,"Message",

JOptionPane.INFORMATION_MESSAGE);

} else {

String pesan1 = "Login Berhasil";

JOptionPane.showMessageDialog(null,pesan1,"Message",

JOptionPane.INFORMATION_MESSAGE);

new Home() .setVisible(true);

dispose();

}

5. Save Lalu Jalankan Programnya

Sebelum menjalankan programnya, masukkan secara manual Username dan Password terlebih dahulu di tabel database yang telah dibuat tadi. isikan bebas saja, kemudian save.

Jika sudah, klik kanan file anda dan Run File.

dan hasil akhir nya akan seperti ini:

B.Membuat kalkulator

Untuk membuat kalkulator ikuti langkah-langkah berikut

Buka aplikasi Netbeans

Pilih menu file – new project

Pilih kategori java – java application

Masukan nama project, misalnya : KalkulatorGUI

Klik next maka project berhasil dibuat.

Selanjutnya pada project tersebut, klik kanan pilih new

Kemudian masukan nama class lalu klik finish.

Gambar diatas merupakan antar muka aplikasi menggunakan Jframe Form. Selanjutnya kita memilih beberapa komponen SWING untuk di drag kedalam layout aplikasi.

Tahap berikut kita mengatur tata letak dan desain pada aplikasinya, Secara sederhana saya membuat desain seperti berikut:

dan untuk kode nya:

Tambahkan code berikut di dalam fungsi tersebut.

if (operasi.getSelectedItem().toString().equalsIgnoreCase("Perkalian")){

int a=Integer.parseInt(bil1.getText());

int b=Integer.parseInt(bil2.getText());

int jumlah=a*b;

hasil.setText (Integer.toString (jumlah));

}

if (operasi.getSelectedItem().toString().equalsIgnoreCase("Pembagian")){

int a=Integer.parseInt(bil1.getText());

int b=Integer.parseInt(bil2.getText());

int jumlah=a/b;

hasil.setText (Integer.toString (jumlah));

}

if (operasi.getSelectedItem().toString().equalsIgnoreCase("Penjumlahan")){

int a=Integer.parseInt(bil1.getText());

int b=Integer.parseInt(bil2.getText());

int jumlah=a+b;

hasil.setText (Integer.toString (jumlah));

}

if (operasi.getSelectedItem().toString().equalsIgnoreCase("Pengurangan")){

int a=Integer.parseInt(bil1.getText());

int b=Integer.parseInt(bil2.getText());

int jumlah=a-b;

hasil.setText (Integer.toString (jumlah));

}

Dan hasil akhir nya adalah:
