1. Buat project baru dan beri nama. Misal
UAS_ArifRamdani_171011400897
2. Buat new java class kemudian masukkan source berikut untuk menyambungkan ke database.
package uasariframdani_171011400897;
import com.mysql.cj.jdbc.MysqlDataSource;
import java.sql.Connection;
import java.sql.SQLException;
import java.util.logging.Level;
import java.util.logging.Logger;
/**
*
* @Arif Ramdani 171011400897
*/
public class Test {
public Connection createConnection(){
Connection connection = null;
MysqlDataSource sql = new MysqlDataSource();
sql.setServerName("localhost");
sql.setPortNumber(3306);
sql.setUser("root");
sql.setPassword("");
sql.setDatabaseName("datawarga");
try {
connection = sql.getConnection();
} catch (SQLException ex) {
Logger.getLogger(Test.class.getName()).log(Level.SEVERE, null, ex);
}
return connection;
}
}
3, Buat JFrame dan masukkan source seperti berikut:
