There are following six steps involved in building a JDBC application −
import java.sql.*;
public class SimpleJDBCProgramExample {
static final String DB_URL = "jdbc:mysql://localhost/testdb";
static final String USER = "guest";
static final String PASS = "guest123";
static final String QUERY = "SELECT id, first, last, age FROM Employees";
public static void main(String[] args) {
Connection conn = null;
Statement stmt = null;
ResultSet rs = null;
try {
conn = DriverManager.getConnection(DB_URL, USER, PASS);
stmt = conn.createStatement();
rs = stmt.executeQuery(QUERY);
while (rs.next()) {
System.out.print("ID: " + rs.getInt("id"));
System.out.print(", Age: " + rs.getInt("age"));
System.out.print(", First: " + rs.getString("first"));
System.out.println(", Last: " + rs.getString("last"));
}
} catch (SQLException e) {
e.printStackTrace();
}
try {
conn.close();
stmt.close();
rs.close();
} catch (Exception e) {
e.printStackTrace();
}
}
}
